By contrast, 15 | the GNU General Public License is intended to guarantee your freedom to 16 | share and change all versions of a program--to make sure it remains free 17 | software for all its users. We, the Free Software Foundation, use the 18 | GNU General Public License for most of our software; it applies also to 19 | any other work released this way by its authors. You can apply it to 20 | your programs, too. 21 | 22 | When we speak of free software, we are referring to freedom, not 23 | price. Our General Public Licenses are designed to make sure that you 24 | have the freedom to distribute copies of free software (and charge for 25 | them if you wish), that you receive source code or can get it if you 26 | want it, that you can change the software or use pieces of it in new 27 | free programs, and that you know you can do these things. 28 | 29 | To protect your rights, we need to prevent others from denying you 30 | these rights or asking you to surrender the rights. Therefore, you have 31 | certain responsibilities if you distribute copies of the software, or if 32 | you modify it: responsibilities to respect the freedom of others. 33 | 34 | For example, if you distribute copies of such a program, whether 35 | gratis or for a fee, you must pass on to the recipients the same 36 | freedoms that you received. You must make sure that they, too, receive 37 | or can get the source code. And you must show them these terms so they 38 | know their rights. 39 | 40 | Developers that use the GNU GPL protect your rights with two steps: 41 | (1) assert copyright on the software, and (2) offer you this License 42 | giving you legal permission to copy, distribute and/or modify it. 43 | 44 | For the developers' and authors' protection, the GPL clearly explains 45 | that there is no warranty for this free software. For both users' and 46 | authors' sake, the GPL requires that modified versions be marked as 47 | changed, so that their problems will not be attributed erroneously to 48 | authors of previous versions. 49 | 50 | Some devices are designed to deny users access to install or run 51 | modified versions of the software inside them, although the manufacturer 52 | can do so. This is fundamentally incompatible with the aim of 53 | protecting users' freedom to change the software. The systematic 54 | pattern of such abuse occurs in the area of products for individuals to 55 | use, which is precisely where it is most unacceptable. Therefore, we 56 | have designed this version of the GPL to prohibit the practice for those 57 | products. If such problems arise substantially in other domains, we 58 | stand ready to extend this provision to those domains in future versions 59 | of the GPL, as needed to protect the freedom of users. 60 | 61 | Finally, every program is threatened constantly by software patents. 62 | States should not allow patents to restrict development and use of 63 | software on general-purpose computers, but in those that do, we wish to 64 | avoid the special danger that patents applied to a free program could 65 | make it effectively proprietary. To prevent this, the GPL assures that 66 | patents cannot be used to render the program non-free. 67 | 68 | The precise terms and conditions for copying, distribution and 69 | modification follow. 70 | 71 | TERMS AND CONDITIONS 72 | 73 | 0. Definitions. 74 | 75 | "This License" refers to version 3 of the GNU General Public License. 76 | 77 | "Copyright" also means copyright-like laws that apply to other kinds of 78 | works, such as semiconductor masks. 79 | 80 | "The Program" refers to any copyrightable work licensed under this 81 | License. Each licensee is addressed as "you". "Licensees" and 82 | "recipients" may be individuals or organizations. 83 | 84 | To "modify" a work means to copy from or adapt all or part of the work 85 | in a fashion requiring copyright permission, other than the making of an 86 | exact copy. The resulting work is called a "modified version" of the 87 | earlier work or a work "based on" the earlier work. 88 | 89 | A "covered work" means either the unmodified Program or a work based 90 | on the Program. 91 | 92 | To "propagate" a work means to do anything with it that, without 93 | permission, would make you directly or secondarily liable for 94 | infringement under applicable copyright law, except executing it on a 95 | computer or modifying a private copy. Propagation includes copying, 96 | distribution (with or without modification), making available to the 97 | public, and in some countries other activities as well. 98 | 99 | To "convey" a work means any kind of propagation that enables other 100 | parties to make or receive copies. Mere interaction with a user through 101 | a computer network, with no transfer of a copy, is not conveying. 102 | 103 | An interactive user interface displays "Appropriate Legal Notices" 104 | to the extent that it includes a convenient and prominently visible 105 | feature that (1) displays an appropriate copyright notice, and (2) 106 | tells the user that there is no warranty for the work (except to the 107 | extent that warranties are provided), that licensees may convey the 108 | work under this License, and how to view a copy of this License. If 109 | the interface presents a list of user commands or options, such as a 110 | menu, a prominent item in the list meets this criterion. 111 | 112 | 1. Source Code. 113 | 114 | The "source code" for a work means the preferred form of the work 115 | for making modifications to it. "Object code" means any non-source 116 | form of a work. 117 | 118 | A "Standard Interface" means an interface that either is an official 119 | standard defined by a recognized standards body, or, in the case of 120 | interfaces specified for a particular programming language, one that 121 | is widely used among developers working in that language. 122 | 123 | The "System Libraries" of an executable work include anything, other 124 | than the work as a whole, that (a) is included in the normal form of 125 | packaging a Major Component, but which is not part of that Major 126 | Component, and (b) serves only to enable use of the work with that 127 | Major Component, or to implement a Standard Interface for which an 128 | implementation is available to the public in source code form. A 129 | "Major Component", in this context, means a major essential component 130 | (kernel, window system, and so on) of the specific operating system 131 | (if any) on which the executable work runs, or a compiler used to 132 | produce the work, or an object code interpreter used to run it. 133 | 134 | The "Corresponding Source" for a work in object code form means all 135 | the source code needed to generate, install, and (for an executable 136 | work) run the object code and to modify the work, including scripts to 137 | control those activities. However, it does not include the work's 138 | System Libraries, or general-purpose tools or generally available free 139 | programs which are used unmodified in performing those activities but 140 | which are not part of the work. For example, Corresponding Source 141 | includes interface definition files associated with source files for 142 | the work, and the source code for shared libraries and dynamically 143 | linked subprograms that the work is specifically designed to require, 144 | such as by intimate data communication or control flow between those 145 | subprograms and other parts of the work. 146 | 147 | The Corresponding Source need not include anything that users 148 | can regenerate automatically from other parts of the Corresponding 149 | Source. 150 | 151 | The Corresponding Source for a work in source code form is that 152 | same work. 153 | 154 | 2. Basic Permissions. 155 | 156 | All rights granted under this License are granted for the term of 157 | copyright on the Program, and are irrevocable provided the stated 158 | conditions are met. This License explicitly affirms your unlimited 159 | permission to run the unmodified Program. The output from running a 160 | covered work is covered by this License only if the output, given its 161 | content, constitutes a covered work. This License acknowledges your 162 | rights of fair use or other equivalent, as provided by copyright law. 163 | 164 | You may make, run and propagate covered works that you do not 165 | convey, without conditions so long as your license otherwise remains 166 | in force. You may convey covered works to others for the sole purpose 167 | of having them make modifications exclusively for you, or provide you 168 | with facilities for running those works, provided that you comply with 169 | the terms of this License in conveying all material for which you do 170 | not control copyright. Those thus making or running the covered works 171 | for you must do so exclusively on your behalf, under your direction 172 | and control, on terms that prohibit them from making any copies of 173 | your copyrighted material outside their relationship with you. 174 | 175 | Conveying under any other circumstances is permitted solely under 176 | the conditions stated below. Sublicensing is not allowed; section 10 177 | makes it unnecessary. 178 | 179 | 3. Protecting Users' Legal Rights From Anti-Circumvention Law. 180 | 181 | No covered work shall be deemed part of an effective technological 182 | measure under any applicable law fulfilling obligations under article 183 | 11 of the WIPO copyright treaty adopted on 20 December 1996, or 184 | similar laws prohibiting or restricting circumvention of such 185 | measures. 186 | 187 | When you convey a covered work, you waive any legal power to forbid 188 | circumvention of technological measures to the extent such circumvention 189 | is effected by exercising rights under this License with respect to 190 | the covered work, and you disclaim any intention to limit operation or 191 | modification of the work as a means of enforcing, against the work's 192 | users, your or third parties' legal rights to forbid circumvention of 193 | technological measures. 194 | 195 | 4. Conveying Verbatim Copies. 196 | 197 | You may convey verbatim copies of the Program's source code as you 198 | receive it, in any medium, provided that you conspicuously and 199 | appropriately publish on each copy an appropriate copyright notice; 200 | keep intact all notices stating that this License and any 201 | non-permissive terms added in accord with section 7 apply to the code; 202 | keep intact all notices of the absence of any warranty; and give all 203 | recipients a copy of this License along with the Program. 204 | 205 | You may charge any price or no price for each copy that you convey, 206 | and you may offer support or warranty protection for a fee. 207 | 208 | 5. Conveying Modified Source Versions. 209 | 210 | You may convey a work based on the Program, or the modifications to 211 | produce it from the Program, in the form of source code under the 212 | terms of section 4, provided that you also meet all of these conditions: 213 | 214 | a) The work must carry prominent notices stating that you modified 215 | it, and giving a relevant date. 216 | 217 | b) The work must carry prominent notices stating that it is 218 | released under this License and any conditions added under section 219 | 7. This requirement modifies the requirement in section 4 to 220 | "keep intact all notices". 221 | 222 | c) You must license the entire work, as a whole, under this 223 | License to anyone who comes into possession of a copy. This 224 | License will therefore apply, along with any applicable section 7 225 | additional terms, to the whole of the work, and all its parts, 226 | regardless of how they are packaged. This License gives no 227 | permission to license the work in any other way, but it does not 228 | invalidate such permission if you have separately received it. 229 | 230 | d) If the work has interactive user interfaces, each must display 231 | Appropriate Legal Notices; however, if the Program has interactive 232 | interfaces that do not display Appropriate Legal Notices, your 233 | work need not make them do so. 234 | 235 | A compilation of a covered work with other separate and independent 236 | works, which are not by their nature extensions of the covered work, 237 | and which are not combined with it such as to form a larger program, 238 | in or on a volume of a storage or distribution medium, is called an 239 | "aggregate" if the compilation and its resulting copyright are not 240 | used to limit the access or legal rights of the compilation's users 241 | beyond what the individual works permit. Inclusion of a covered work 242 | in an aggregate does not cause this License to apply to the other 243 | parts of the aggregate. 244 | 245 | 6. Conveying Non-Source Forms. 246 | 247 | You may convey a covered work in object code form under the terms 248 | of sections 4 and 5, provided that you also convey the 249 | machine-readable Corresponding Source under the terms of this License, 250 | in one of these ways: 251 | 252 | a) Convey the object code in, or embodied in, a physical product 253 | (including a physical distribution medium), accompanied by the 254 | Corresponding Source fixed on a durable physical medium 255 | customarily used for software interchange. 256 | 257 | b) Convey the object code in, or embodied in, a physical product 258 | (including a physical distribution medium), accompanied by a 259 | written offer, valid for at least three years and valid for as 260 | long as you offer spare parts or customer support for that product 261 | model, to give anyone who possesses the object code either (1) a 262 | copy of the Corresponding Source for all the software in the 263 | product that is covered by this License, on a durable physical 264 | medium customarily used for software interchange, for a price no 265 | more than your reasonable cost of physically performing this 266 | conveying of source, or (2) access to copy the 267 | Corresponding Source from a network server at no charge. 268 | 269 | c) Convey individual copies of the object code with a copy of the 270 | written offer to provide the Corresponding Source. This 271 | alternative is allowed only occasionally and noncommercially, and 272 | only if you received the object code with such an offer, in accord 273 | with subsection 6b. 274 | 275 | d) Convey the object code by offering access from a designated 276 | place (gratis or for a charge), and offer equivalent access to the 277 | Corresponding Source in the same way through the same place at no 278 | further charge. You need not require recipients to copy the 279 | Corresponding Source along with the object code. If the place to 280 | copy the object code is a network server, the Corresponding Source 281 | may be on a different server (operated by you or a third party) 282 | that supports equivalent copying facilities, provided you maintain 283 | clear directions next to the object code saying where to find the 284 | Corresponding Source. Regardless of what server hosts the 285 | Corresponding Source, you remain obligated to ensure that it is 286 | available for as long as needed to satisfy these requirements. 287 | 288 | e) Convey the object code using peer-to-peer transmission, provided 289 | you inform other peers where the object code and Corresponding 290 | Source of the work are being offered to the general public at no 291 | charge under subsection 6d. 292 | 293 | A separable portion of the object code, whose source code is excluded 294 | from the Corresponding Source as a System Library, need not be 295 | included in conveying the object code work. 296 | 297 | A "User Product" is either (1) a "consumer product", which means any 298 | tangible personal property which is normally used for personal, family, 299 | or household purposes, or (2) anything designed or sold for incorporation 300 | into a dwelling. In determining whether a product is a consumer product, 301 | doubtful cases shall be resolved in favor of coverage. For a particular 302 | product received by a particular user, "normally used" refers to a 303 | typical or common use of that class of product, regardless of the status 304 | of the particular user or of the way in which the particular user 305 | actually uses, or expects or is expected to use, the product. A product 306 | is a consumer product regardless of whether the product has substantial 307 | commercial, industrial or non-consumer uses, unless such uses represent 308 | the only significant mode of use of the product. 309 | 310 | "Installation Information" for a User Product means any methods, 311 | procedures, authorization keys, or other information required to install 312 | and execute modified versions of a covered work in that User Product from 313 | a modified version of its Corresponding Source. The information must 314 | suffice to ensure that the continued functioning of the modified object 315 | code is in no case prevented or interfered with solely because 316 | modification has been made. 317 | 318 | If you convey an object code work under this section in, or with, or 319 | specifically for use in, a User Product, and the conveying occurs as 320 | part of a transaction in which the right of possession and use of the 321 | User Product is transferred to the recipient in perpetuity or for a 322 | fixed term (regardless of how the transaction is characterized), the 323 | Corresponding Source conveyed under this section must be accompanied 324 | by the Installation Information. But this requirement does not apply 325 | if neither you nor any third party retains the ability to install 326 | modified object code on the User Product (for example, the work has 327 | been installed in ROM). 328 | 329 | The requirement to provide Installation Information does not include a 330 | requirement to continue to provide support service, warranty, or updates 331 | for a work that has been modified or installed by the recipient, or for 332 | the User Product in which it has been modified or installed. Access to a 333 | network may be denied when the modification itself materially and 334 | adversely affects the operation of the network or violates the rules and 335 | protocols for communication across the network. 336 | 337 | Corresponding Source conveyed, and Installation Information provided, 338 | in accord with this section must be in a format that is publicly 339 | documented (and with an implementation available to the public in 340 | source code form), and must require no special password or key for 341 | unpacking, reading or copying. 342 | 343 | 7. Additional Terms. 344 | 345 | "Additional permissions" are terms that supplement the terms of this 346 | License by making exceptions from one or more of its conditions. 347 | Additional permissions that are applicable to the entire Program shall 348 | be treated as though they were included in this License, to the extent 349 | that they are valid under applicable law. If additional permissions 350 | apply only to part of the Program, that part may be used separately 351 | under those permissions, but the entire Program remains governed by 352 | this License without regard to the additional permissions. 353 | 354 | When you convey a copy of a covered work, you may at your option 355 | remove any additional permissions from that copy, or from any part of 356 | it. (Additional permissions may be written to require their own 357 | removal in certain cases when you modify the work.) You may place 358 | additional permissions on material, added by you to a covered work, 359 | for which you have or can give appropriate copyright permission. 360 | 361 | Notwithstanding any other provision of this License, for material you 362 | add to a covered work, you may (if authorized by the copyright holders of 363 | that material) supplement the terms of this License with terms: 364 | 365 | a) Disclaiming warranty or limiting liability differently from the 366 | terms of sections 15 and 16 of this License; or 367 | 368 | b) Requiring preservation of specified reasonable legal notices or 369 | author attributions in that material or in the Appropriate Legal 370 | Notices displayed by works containing it; or 371 | 372 | c) Prohibiting misrepresentation of the origin of that material, or 373 | requiring that modified versions of such material be marked in 374 | reasonable ways as different from the original version; or 375 | 376 | d) Limiting the use for publicity purposes of names of licensors or 377 | authors of the material; or 378 | 379 | e) Declining to grant rights under trademark law for use of some 380 | trade names, trademarks, or service marks; or 381 | 382 | f) Requiring indemnification of licensors and authors of that 383 | material by anyone who conveys the material (or modified versions of 384 | it) with contractual assumptions of liability to the recipient, for 385 | any liability that these contractual assumptions directly impose on 386 | those licensors and authors. 387 | 388 | All other non-permissive additional terms are considered "further 389 | restrictions" within the meaning of section 10. If the Program as you 390 | received it, or any part of it, contains a notice stating that it is 391 | governed by this License along with a term that is a further 392 | restriction, you may remove that term. If a license document contains 393 | a further restriction but permits relicensing or conveying under this 394 | License, you may add to a covered work material governed by the terms 395 | of that license document, provided that the further restriction does 396 | not survive such relicensing or conveying. 397 | 398 | If you add terms to a covered work in accord with this section, you 399 | must place, in the relevant source files, a statement of the 400 | additional terms that apply to those files, or a notice indicating 401 | where to find the applicable terms. 402 | 403 | Additional terms, permissive or non-permissive, may be stated in the 404 | form of a separately written license, or stated as exceptions; 405 | the above requirements apply either way. 406 | 407 | 8. Termination. 408 | 409 | You may not propagate or modify a covered work except as expressly 410 | provided under this License. Any attempt otherwise to propagate or 411 | modify it is void, and will automatically terminate your rights under 412 | this License (including any patent licenses granted under the third 413 | paragraph of section 11). 414 | 415 | However, if you cease all violation of this License, then your 416 | license from a particular copyright holder is reinstated (a) 417 | provisionally, unless and until the copyright holder explicitly and 418 | finally terminates your license, and (b) permanently, if the copyright 419 | holder fails to notify you of the violation by some reasonable means 420 | prior to 60 days after the cessation. 421 | 422 | Moreover, your license from a particular copyright holder is 423 | reinstated permanently if the copyright holder notifies you of the 424 | violation by some reasonable means, this is the first time you have 425 | received notice of violation of this License (for any work) from that 426 | copyright holder, and you cure the violation prior to 30 days after 427 | your receipt of the notice. 428 | 429 | Termination of your rights under this section does not terminate the 430 | licenses of parties who have received copies or rights from you under 431 | this License. If your rights have been terminated and not permanently 432 | reinstated, you do not qualify to receive new licenses for the same 433 | material under section 10. 434 | 435 | 9. Acceptance Not Required for Having Copies. 436 | 437 | You are not required to accept this License in order to receive or 438 | run a copy of the Program. Ancillary propagation of a covered work 439 | occurring solely as a consequence of using peer-to-peer transmission 440 | to receive a copy likewise does not require acceptance. However, 441 | nothing other than this License grants you permission to propagate or 442 | modify any covered work. These actions infringe copyright if you do 443 | not accept this License. Therefore, by modifying or propagating a 444 | covered work, you indicate your acceptance of this License to do so. 445 | 446 | 10. Automatic Licensing of Downstream Recipients. 447 | 448 | Each time you convey a covered work, the recipient automatically 449 | receives a license from the original licensors, to run, modify and 450 | propagate that work, subject to this License. You are not responsible 451 | for enforcing compliance by third parties with this License. 452 | 453 | An "entity transaction" is a transaction transferring control of an 454 | organization, or substantially all assets of one, or subdividing an 455 | organization, or merging organizations. If propagation of a covered 456 | work results from an entity transaction, each party to that 457 | transaction who receives a copy of the work also receives whatever 458 | licenses to the work the party's predecessor in interest had or could 459 | give under the previous paragraph, plus a right to possession of the 460 | Corresponding Source of the work from the predecessor in interest, if 461 | the predecessor has it or can get it with reasonable efforts. 462 | 463 | You may not impose any further restrictions on the exercise of the 464 | rights granted or affirmed under this License. For example, you may 465 | not impose a license fee, royalty, or other charge for exercise of 466 | rights granted under this License, and you may not initiate litigation 467 | (including a cross-claim or counterclaim in a lawsuit) alleging that 468 | any patent claim is infringed by making, using, selling, offering for 469 | sale, or importing the Program or any portion of it. 470 | 471 | 11. Patents. 472 | 473 | A "contributor" is a copyright holder who authorizes use under this 474 | License of the Program or a work on which the Program is based. The 475 | work thus licensed is called the contributor's "contributor version". 476 | 477 | A contributor's "essential patent claims" are all patent claims 478 | owned or controlled by the contributor, whether already acquired or 479 | hereafter acquired, that would be infringed by some manner, permitted 480 | by this License, of making, using, or selling its contributor version, 481 | but do not include claims that would be infringed only as a 482 | consequence of further modification of the contributor version. For 483 | purposes of this definition, "control" includes the right to grant 484 | patent sublicenses in a manner consistent with the requirements of 485 | this License. 486 | 487 | Each contributor grants you a non-exclusive, worldwide, royalty-free 488 | patent license under the contributor's essential patent claims, to 489 | make, use, sell, offer for sale, import and otherwise run, modify and 490 | propagate the contents of its contributor version. 491 | 492 | In the following three paragraphs, a "patent license" is any express 493 | agreement or commitment, however denominated, not to enforce a patent 494 | (such as an express permission to practice a patent or covenant not to 495 | sue for patent infringement). To "grant" such a patent license to a 496 | party means to make such an agreement or commitment not to enforce a 497 | patent against the party. 498 | 499 | If you convey a covered work, knowingly relying on a patent license, 500 | and the Corresponding Source of the work is not available for anyone 501 | to copy, free of charge and under the terms of this License, through a 502 | publicly available network server or other readily accessible means, 503 | then you must either (1) cause the Corresponding Source to be so 504 | available, or (2) arrange to deprive yourself of the benefit of the 505 | patent license for this particular work, or (3) arrange, in a manner 506 | consistent with the requirements of this License, to extend the patent 507 | license to downstream recipients. "Knowingly relying" means you have 508 | actual knowledge that, but for the patent license, your conveying the 509 | covered work in a country, or your recipient's use of the covered work 510 | in a country, would infringe one or more identifiable patents in that 511 | country that you have reason to believe are valid. 512 | 513 | If, pursuant to or in connection with a single transaction or 514 | arrangement, you convey, or propagate by procuring conveyance of, a 515 | covered work, and grant a patent license to some of the parties 516 | receiving the covered work authorizing them to use, propagate, modify 517 | or convey a specific copy of the covered work, then the patent license 518 | you grant is automatically extended to all recipients of the covered 519 | work and works based on it. 520 | 521 | A patent license is "discriminatory" if it does not include within 522 | the scope of its coverage, prohibits the exercise of, or is 523 | conditioned on the non-exercise of one or more of the rights that are 524 | specifically granted under this License. You may not convey a covered 525 | work if you are a party to an arrangement with a third party that is 526 | in the business of distributing software, under which you make payment 527 | to the third party based on the extent of your activity of conveying 528 | the work, and under which the third party grants, to any of the 529 | parties who would receive the covered work from you, a discriminatory 530 | patent license (a) in connection with copies of the covered work 531 | conveyed by you (or copies made from those copies), or (b) primarily 532 | for and in connection with specific products or compilations that 533 | contain the covered work, unless you entered into that arrangement, 534 | or that patent license was granted, prior to 28 March 2007. 535 | 536 | Nothing in this License shall be construed as excluding or limiting 537 | any implied license or other defenses to infringement that may 538 | otherwise be available to you under applicable patent law. 539 | 540 | 12. No Surrender of Others' Freedom. 541 | 542 | If conditions are imposed on you (whether by court order, agreement or 543 | otherwise) that contradict the conditions of this License, they do not 544 | excuse you from the conditions of this License. If you cannot convey a 545 | covered work so as to satisfy simultaneously your obligations under this 546 | License and any other pertinent obligations, then as a consequence you may 547 | not convey it at all. For example, if you agree to terms that obligate you 548 | to collect a royalty for further conveying from those to whom you convey 549 | the Program, the only way you could satisfy both those terms and this 550 | License would be to refrain entirely from conveying the Program. 551 | 552 | 13. Use with the GNU Affero General Public License. 553 | 554 | Notwithstanding any other provision of this License, you have 555 | permission to link or combine any covered work with a work licensed 556 | under version 3 of the GNU Affero General Public License into a single 557 | combined work, and to convey the resulting work. The terms of this 558 | License will continue to apply to the part which is the covered work, 559 | but the special requirements of the GNU Affero General Public License, 560 | section 13, concerning interaction through a network will apply to the 561 | combination as such. 562 | 563 | 14. Revised Versions of this License. 564 | 565 | The Free Software Foundation may publish revised and/or new versions of 566 | the GNU General Public License from time to time. Such new versions will 567 | be similar in spirit to the present version, but may differ in detail to 568 | address new problems or concerns. 569 | 570 | Each version is given a distinguishing version number. If the 571 | Program specifies that a certain numbered version of the GNU General 572 | Public License "or any later version" applies to it, you have the 573 | option of following the terms and conditions either of that numbered 574 | version or of any later version published by the Free Software 575 | Foundation. If the Program does not specify a version number of the 576 | GNU General Public License, you may choose any version ever published 577 | by the Free Software Foundation. 578 | 579 | If the Program specifies that a proxy can decide which future 580 | versions of the GNU General Public License can be used, that proxy's 581 | public statement of acceptance of a version permanently authorizes you 582 | to choose that version for the Program. 583 | 584 | Later license versions may give you additional or different 585 | permissions. However, no additional obligations are imposed on any 586 | author or copyright holder as a result of your choosing to follow a 587 | later version. 588 | 589 | 15. Disclaimer of Warranty. 590 | 591 | THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY 592 | APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT 593 | HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY 594 | OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, 595 | THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR 596 | PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM 597 | IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF 598 | ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 599 | 600 | 16. Limitation of Liability. 601 | 602 | IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 603 | WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS 604 | THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY 605 | GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE 606 | USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF 607 | DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD 608 | PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), 609 | EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF 610 | SUCH DAMAGES. 611 | 612 | 17. Interpretation of Sections 15 and 16. 613 | 614 | If the disclaimer of warranty and limitation of liability provided 615 | above cannot be given local legal effect according to their terms, 616 | reviewing courts shall apply local law that most closely approximates 617 | an absolute waiver of all civil liability in connection with the 618 | Program, unless a warranty or assumption of liability accompanies a 619 | copy of the Program in return for a fee. 620 | 621 | END OF TERMS AND CONDITIONS 622 | 623 | How to Apply These Terms to Your New Programs 624 | 625 | If you develop a new program, and you want it to be of the greatest 626 | possible use to the public, the best way to achieve this is to make it 627 | free software which everyone can redistribute and change under these terms. 628 | 629 | To do so, attach the following notices to the program. It is safest 630 | to attach them to the start of each source file to most effectively 631 | state the exclusion of warranty; and each file should have at least 632 | the "copyright" line and a pointer to where the full notice is found. 633 | 634 | 635 | Copyright (C) 636 | 637 | This program is free software: you can redistribute it and/or modify 638 | it under the terms of the GNU General Public License as published by 639 | the Free Software Foundation, either version 3 of the License, or 640 | (at your option) any later version. 641 | 642 | This program is distributed in the hope that it will be useful, 643 | but WITHOUT ANY WARRANTY; without even the implied warranty of 644 | MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the 645 | GNU General Public License for more details. 646 | 647 | You should have received a copy of the GNU General Public License 648 | along with this program. If not, see . 649 | 650 | Also add information on how to contact you by electronic and paper mail. 651 | 652 | If the program does terminal interaction, make it output a short 653 | notice like this when it starts in an interactive mode: 654 | 655 | Copyright (C) 656 | This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. 657 | This is free software, and you are welcome to redistribute it 658 | under certain conditions; type `show c' for details. 659 | 660 | The hypothetical commands `show w' and `show c' should show the appropriate 661 | parts of the General Public License. Of course, your program's commands 662 | might be different; for a GUI interface, you would use an "about box". 663 | 664 | You should also get your employer (if you work as a programmer) or school, 665 | if any, to sign a "copyright disclaimer" for the program, if necessary. 666 | For more information on this, and how to apply and follow the GNU GPL, see 667 | . 668 | 669 | The GNU General Public License does not permit incorporating your program 670 | into proprietary programs. If your program is a subroutine library, you 671 | may consider it more useful to permit linking proprietary applications with 672 | the library. If this is what you want to do, use the GNU Lesser General 673 | Public License instead of this License. But first, please read 674 | . 675 | -------------------------------------------------------------------------------- /README.md: -------------------------------------------------------------------------------- 1 | 2 | # OSMData 3 | 4 | The [OpenStreetMap project](https://www.openstreetmap.org/) collects an amazing 5 | amount of geodata and makes it available to the world for free. But the raw 6 | OpenStreetMap data is hard to use. This repository contains scripts to set up 7 | a server that processes some OSM data and brings it into a format for easier 8 | use. 9 | 10 | Currently these scripts can be used to derive 11 | 12 | * Coastline data (in the form of linestrings or land or water polygons for the 13 | worlds land masses or oceans). 14 | * Antarctic icesheet data. 15 | 16 | datasets from OSM data. 17 | 18 | The icesheet scripts are based on https://github.com/imagico/icesheet_proc. 19 | 20 | ## Public server 21 | 22 | A server running this code and offering the results for download to the general 23 | public is at https://osmdata.openstreetmap.de/ . 24 | 25 | ## Overview 26 | 27 | The scripts are intended to work in the [Hetzner 28 | Cloud](https://www.hetzner.com/cloud). But it should be possible to port 29 | them to other cloud providers. 30 | 31 | One server runs all the time as webserver and "master of ceremonies". It will 32 | start other servers regularly to update a planet file and do the data 33 | processing. The results are then copied back to the master server and are 34 | available for download from there. 35 | 36 | ## Setting up a master server 37 | 38 | See [the master README](master/README.md) on how to set up a master server. 39 | 40 | ## License 41 | 42 | Unless otherwise mentioned everything in the repository is available under 43 | the GNU GENERAL PUBLIC LICENSE Version 3. See the file COPYING for the 44 | complete text of the license. 45 | 46 | -------------------------------------------------------------------------------- /master/README.md: -------------------------------------------------------------------------------- 1 | 2 | # Setup of Master Server 3 | 4 | The files in this directory are used to set up the master server. You will 5 | need an [Hetzner cloud](https://www.hetzner.com/cloud) account and the 6 | [hcloud command line tool](https://github.com/hetznercloud/cli). 7 | 8 | Here are the steps needed to install the master server: 9 | 10 | * Go to the [Hetzner Cloud console](https://console.hetzner.cloud/) and log 11 | in. 12 | * Add a new project. 13 | * Add one or more of your ssh public keys. Name one `admin`. 14 | * Add a new API token to the project. Put the API token somewhere safe. 15 | * Create a hcloud context on your own machine: `hcloud context create osmdata`. 16 | It will ask you for the token you have just created. 17 | * Create a new cloud server. (You can use the `--ssh-key` option multiple 18 | times if you have several keys to add.) On your own machine run: 19 | 20 | ``` 21 | hcloud server create \ 22 | --name osmdata \ 23 | --location nbg1 \ 24 | --type cx11 \ 25 | --image debian-12 \ 26 | --ssh-key admin 27 | ``` 28 | 29 | This uses the cheapest cloud server they have which costs 4.51 EUR per month. 30 | 31 | * Still on your own machine, create a new volume: 32 | 33 | ``` 34 | hcloud volume create \ 35 | --name planet \ 36 | --size 120 \ 37 | --server osmdata \ 38 | --format ext4 \ 39 | --automount 40 | ``` 41 | 42 | * You should now be able to log into the master server as root (`hcloud server 43 | ssh osmdata`) and see a volume mounted somewhere under `/mnt`. 44 | * Copy the script `init.sh` to the new server and run it as `root` user: 45 | 46 | ``` 47 | IP=`hcloud server describe -o 'format={{.PublicNet.IPv4.IP}}' osmdata` 48 | echo $IP 49 | scp osmdata/master/init.sh root@$IP:/tmp/ 50 | ssh -t root@$IP /tmp/init.sh 51 | ``` 52 | 53 | The script will ask for the Hetzner cloud token at some point which you have to 54 | enter. The `-t` option on the `ssh` command is important, otherwise it can't 55 | ask for the token. 56 | 57 | * If his script runs through without errors, you are done with the update of 58 | the master server and you can now log in as the `robot` user: 59 | 60 | ``` 61 | hcloud server ssh -u robot osmdata 62 | ``` 63 | 64 | # Operation 65 | 66 | On the master server, you have a script `/usr/local/bin/run-update.sh` which 67 | can be run as `robot` user to do an update run. The first time this is run, it 68 | will download a complete planet and update it using the hourly replication 69 | files. Further runs will update from the planet of the last run. This will also 70 | run the data processing and put the results into `/data/new/`. 71 | 72 | After testing this you might want to create a cronjob for it. 73 | 74 | See the comments at the beginning of the `run-update.sh` script for some 75 | options. 76 | 77 | 78 | # Notes 79 | 80 | * The init script installs the `certbot` software for setting up LetsEncrypt 81 | certificates, but doesn't actually use it. You have to do the TLS setup 82 | manually if you want it. For this call 83 | `certbot certonly --webroot -w /var/lib/letsencrypt/webroot/ -d osmdata.openstreetmap.de`. 84 | After that you can activate the SSL web site: `a2ensite 000-default-ssl.conf`. 85 | * While testing you might want to run the update script in 86 | [tmux](https://github.com/tmux/tmux), because it will run for a few hours. 87 | `tmux` is already installed on the system. 88 | 89 | -------------------------------------------------------------------------------- /master/acme-challenge.conf: -------------------------------------------------------------------------------- 1 | Alias "/.well-known/acme-challenge/" "/var/lib/letsencrypt/webroot/.well-known/acme-challenge/" 2 | 3 | AllowOverride None 4 | Options None 5 | Require all granted 6 | 7 | -------------------------------------------------------------------------------- /master/apache-ssl.conf: -------------------------------------------------------------------------------- 1 | 2 | 3 | ServerName osmdata.openstreetmap.de 4 | ServerAdmin webmaster@localhost 5 | DocumentRoot /srv/www/osmdata 6 | 7 | Header always set X-Frame-Options "DENY" 8 | Header always set X-XSS-Protection "1;

The coastline in OpenStreetMap is often broken. The update process will try 5 | to repair it, but this does not always work. If the OSM data can't be repaired 6 | automatically, the data here will not be updated.

Coastline data sets

7 | 8 |

In OpenStreetMap the primary division of the earth surface into land and 9 | water is mapped through ways tagged with natural=coastline. For 10 | rendering a map however you usually need land or water polygons representing 11 | continents and islands in the former or oceans in the latter case.

12 | 13 |

Assembling these polygons from the coastline ways in OpenStreetMap is done 14 | with a specialized processing tool (OSMCoastline). Learn more about the coastline 16 | processing...

17 | 18 |

The results of this can be downloaded here.

Coastlines

11 | 12 |

Linestrings for coastlines. Long linestrings are split into smaller chunks 13 | (with no more than 100 points) that are easier and faster to work with.

14 | 15 |

Description

16 | 17 |

The data has been derived from OpenStreetMap ways tagged with 18 | natural=coastline. Some errors in the OSM data are repaired in the 19 | process. Learn more about the coastline processing...

20 | 21 |

This dataset can be used together with the land or water 23 | polygons.

24 | 25 |

Variants

26 | 27 |
    28 |
  • The data is available in WGS84 29 | and Mercator 30 | projection.

Antarctic icesheet outlines

11 | 12 |

Linestrings for the outlines of the ice covered parts of the Antarctic that 13 | are not explicitly mapped as glaciers in OpenStreetMap. Linestrings are split 14 | into smaller chunks (no more than 200 km length in projected coordinates) that 15 | are easier and faster to work with.

16 | 17 |

Description

18 | 19 |

These files are based on the OpenStreetMap data of land ice in the Antarctic 20 | south of -60 degrees latitude which according to the OSM mapping 22 | conventions for the Antarctic is not represented by polygons. You need the 23 | data here to properly render glaciers in the Antarctic in a map without special 24 | local adaptations to your map style. Learn more 25 | about the Antarctic Icesheet processing...

26 | 27 |

The icesheet outlines in particular are needed if you render glaciers with 28 | explicitly drawn outlines, otherwise you only need the Antarctic icesheet polygons.

30 | 31 |

Attributes

32 | 33 |

The files contain an ice_edge attribute which can have three 34 | different values with the following meaning:

35 | 36 |
    37 |
  • ice_ocean indicates outline segments separating ice from ocean
    • 38 |
  • ice_land indicates outline segments separating ice from ice free land
    • 39 |
  • ice_ice indicates outline segments separating implicit ice areas from glaciers explicitly mapped in OpenStreetMap
    • 40 |
41 | 42 |

Using this data

43 | 44 |

To use this data in an OpenStreetMap based map download the shapefile below, 45 | include it as a separate layer in your map style and render features with 46 | ice_edge=ice_ocean and ice_edge=ice_land with the same 47 | styling as used for glacier outlines.

24 | 25 |

Like in case of the Land Polygons these 26 | are split into smaller polygons for easier use.

Using this data

29 | 30 |

To use this data in an OpenStreetMap based map download the shapefile below, 31 | include it as a separate layer in your map style and render it with the same 32 | fill color/pattern as used for glacier polygons. If your map style renders 33 | glaciers with an outline you also need the Antarctic icesheet outlines.

Antarctic icesheet datasets

7 | 8 |

In the Antarctic, south of -60 degrees latitude, glaciation is not explicitly 10 | mapped in OpenStreetMap to avoid huge polygons that are difficult to 11 | handle. Instead it is assumed that all land areas that are not explicitly 12 | mapped otherwise are covered by ice. This needs to be taken into consideration 13 | when interpreting the OpenStreetMap data like for rendering a map. The data 14 | here was created to make this easier. 15 | Learn more about the Antarctic Icesheet processing...

Land polygons

11 | 12 |

Polygons for all land areas in the world, ie. continents and islands. Optionally, 13 | large polygons are split into smaller overlapping chunks that are easier and faster 14 | to work with.

15 | 16 |

Description

17 | 18 |

The data has been derived from OpenStreetMap ways tagged with 19 | natural=coastline. Ways are assembled into polygons and then 20 | split. Some errors in the OSM data are repaired in the process. 21 | Learn more about the coastline processing...

22 | 23 |

Where polygons have been split they overlap slightly to help avoiding 24 | rendering artefacts at the seams.

25 | 26 |

Variants

    29 |
  • Large polygons are available as complete polygons or split into 30 | smaller polygons.

Waterbodies Data Sets

7 | 8 |

Apart from the coastline OpenStreetMap contains a 9 | lot of other data on surface waterbodies like lakes, rivers and reservoirs. In 10 | OpenStreetMap data based maps these are typically rendered from a rendering 11 | database that also contains most of the other data used in the map.

12 | 13 |

For the coarse scales (low zoom levels) this data is however too detailed 14 | and voluminous to be rendered efficiently. We offer a compact version of this 15 | data reduced significantly in volume and complexity which still produces 16 | results very close to those with the full detail data when rendered in plain 17 | color without outlines. 18 | Learn more about the waterbody processing...

The OpenStreetMap project 12 | collects an amazing amount of geodata and makes it available to the world for 13 | free. But the raw OpenStreetMap data is hard to use. On this web site you'll 14 | find some of that data pre-processed and formatted for easier use.

15 | 16 |

Pre-processing includes removing or fixing of wrong data and assembling of 17 | different parts of the data into a usable whole. The data is formatted into Shapefiles for easy use in the usual 19 | GIS applications.

20 | 21 |

The following data sets are available from this site:

Downloading

7 | 8 |

All data is available for free download. Use the [Download] buttons on 9 | the data pages. Files can be quite large (up to several 10 | hundred megabytes), so make sure to only download what you need.

11 | 12 |

All downloads are compressed in zip archives.

13 | 14 | 15 |

Recurring downloads

16 | 17 |

Updated data is usally available once a day. Some data is updated less often 18 | if it doesn't change much. You can use automation to re-download new versions 19 | of the data, but please use the If-Modified-Since header. This will 20 | make sure that data is only downloaded if it actually changed.

21 | 22 |

Use the curl program for downloading, it supports 23 | the -z, --time-cond option. You can set it up easily so that 24 | it will only re-download a file if it has changed.

25 | 26 |

If you abuse this service and download the date more often than necessary, 27 | we might suspend the service without notice!

Data formats

7 | 8 |

Most data available on this site currently uses the popular Shapefile 9 | format. Other formats might be added in the future.

10 | 11 |

Shapefile

 12 | 13 |

This is a popular format for GIS data. Each layer consists of a set of 14 | files. For easy download all the files are packed into a zip archive. The 15 | archive contains the following files:

16 | 17 | 18 | 19 | 20 | 21 | 22 | 23 | 24 |
LAYER.shpFeature geometries
LAYER.shxFeature geometry index
LAYER.dbfFeature attributes
LAYER.prjProjection used
LAYER.cpgCode page for character encoding
README.txtInformation about this layer
25 | 26 |

All string attributes use the Unicode UTF-8 character encoding, the same as 27 | the OpenStreetMap data.

28 | 29 |

See the Wikipedia for 31 | more details about this format.

32 | 33 | {% comment %} 34 |

GeoTIFF raster image

 35 | 36 |

Raster data is currently made available in GeoTIFF format with Deflate compression.

37 | 38 |

See the GeoTIFF standard page 39 | for more details about this format.

All of the data on this site is derived from the original OpenStreetMap data and is available 22 | under open licenses. See the license page for 23 | more details.

24 | 25 |

Because the data is directly derived from OpenStreetMap data, errors in OSM 26 | data will appear in this data, too. Don't ask us to fix those errors, you can 27 | do that in OpenStreetMap yourself.

28 | 29 |

You can get the original OpenStreetMap data from the official download site at 30 | planet.openstreetmap.org.

Projections/Spatial reference systems

7 | 8 |

Data available on this site is in one of these two projections/spatial 9 | reference systems.

10 | 11 |

WGS84 (EPSG 4326)

 12 | 13 |

OpenStreetMap uses the WGS84 spatial reference system used by the Global 14 | Positioning System (GPS). It uses geographic coordinates between -180° and 180° 15 | longitude and -90° and 90° latitude. So this is the "native" OSM format.

16 | 17 |

This is the right choice for you if you need geographical 18 | coordinates or want to transform the coordinates into some other spatial 19 | reference system or projection.

20 | 21 |

Mercator (EPSG 3857)

 22 | 23 |

Most tiled web maps (such as the standard OSM maps and Google Maps) use this 24 | Mercator projection.

25 | 26 |

The map area of such maps is a square with x and y coordiates both between 27 | -20,037,508.34 and 20,037,508.34 meters. As a result data north of about 85.1° 28 | and south of about -85.1° latitude can not be shown and has been cut off.

29 | 30 |

The correct EPSG code for this data is 3857 and this is what the data files 31 | show. Before this code was allocated, other codes such as 900913 were used. If 32 | your software does not understand the 3857 code you might need to upgrade. See 33 | this page 34 | for all the details.

35 | 36 |

This is the right choice for you if you are creating tiled web 37 | maps.

Coastline processing

7 | 8 | 9 |

The coastline in OSM

10 | 11 |

The coastline is handled somewhat differently than most other features in 12 | OSM. To mark it ways with the tag natural=coastline are used. Those 13 | ways need to connect end-to-end to form an unbroken line around every island 14 | and every continent. And the land always has to be on the left side, the water 15 | on the right side of those ways. For details see the 16 | OSM wiki. 18 | 19 | 20 |

Processing with OSMCoastline

21 | 22 |

The world is big and all the coastlines together are very very long. So 23 | there is a lot of data. And chances are that at any moment someone somewhere 24 | is updating the coastline. And that is not always easy to do, and errors happen. 25 | But we need one unbroken line to form proper (multi)polygons of land masses 26 | (or the sea). Specifically for this task we have developed the OSMCoastline program. It assembles 28 | all the data, applies some fixes if necessary and creates the data you see on 29 | this site. For more of the inner workings refer to the OSMCoastline 30 | documentation or have a look at these blog 32 | posts. OSMCoastline has many parameters and options and you can run it 33 | yourself to create specialized output if what you see on this site is not 34 | enough for your use case.

35 | 36 | 37 |

Finding and fixing errors

38 | 39 |

As the OSMCoastline program runs to create the coastline, it will report any 40 | errors in the coastline it finds. This information is then sent on to the 41 | Coastline view of the 43 | Geofabrik OSM Inspector. You can help fixing the OSM data by checking 44 | that site and correcting any errors you see. Thanks to all the OSM users who 45 | do this!

46 | 47 |

If you can't find an error shown by the OSM Inspector in your 48 | OSM editor, chances are somebody else was faster and has already fixed it!

Information on generalization

7 | 8 | 9 | 10 |

Most OpenStreetMap-based maps are rendered from exactly the same data on all 11 | scales. This means that at low zoom levels there is usually way too much 12 | geometric detail which produces a lot of noise and blurriness in the results by 13 | rendering details that cannot be properly represented at the map scale and 14 | resolution used.

15 | 16 |

The process of adapting the detailed map data as it has been surveyed to the 17 | target map scale and resolution is called cartographic generalization. 18 | This is neglected in most digital zoomable maps. Key to good quality 19 | generalization and ultimately clear and well readable maps is the elimination 20 | of unimportant details that cannot be properly shown and at the same time 21 | selection and emphasis of key elements. This is not to be confused with mere 22 | geometric simplification which is just one element of generalization and which 23 | is widely used in digital map production.

24 | 25 |

Generalized coastlines

26 | 27 |

We provide a generalized version of the 28 | OpenStreetMap coastlines for use in web 29 | maps in Mercator projection. The coastline is usually the most important 30 | element of maps at the lowest zoom levels so generalization is most important 31 | here.

32 | 33 |

The technique used is a raster-based process implemented in the coastline_gen tool. It 35 | ensures that straits and land bridges are properly represented at the low 36 | resolutions. Different levels of generalization are produced for the different 37 | zoom levels up to z=8.

38 | 39 |

40 | 41 | 42 | 43 | 44 |

45 | 46 |

After the original coastline data processing two further steps are used:

47 | 48 |
    49 |
  • Any lakes tagged natural=coastline will be removed.
    • 50 |
  • Some marine coastal water areas, primarily at the mouths of rivers, that 51 | are not included in the coastline in OpenStreetMap are added based on the 52 | maritime=yes tag.
    • 53 |
54 | 55 |

Rendering example

Antarctic icesheet processing

7 | 8 | 9 | 10 |

Land in the Antarctic is more than 90 percent covered by ice. It was 11 | therefore decided some time 13 | ago in OpenStreetMap that the ice cover in general is not to be explicitly 14 | mapped and instead it is assumed that all land (as mapped by the coastline) is ice-covered south of 60 16 | degrees southern latitude unless it is explicitly mapped otherwise.

17 | 18 |

This convention simplifies mapping a lot but it also produces some 19 | difficulties for data users since they need to take this into account if they 20 | want to correctly interpret the OpenStreetMap data.

21 | 22 |

If you render a map displaying glaciers and icesheets based on OpenStreetMap 23 | data you can either modify the rendering style locally in the Antarctic to take 24 | care of the different tagging rules or you use the Antarctic icesheet data provided here in 26 | addition to the normal glacier polygons from OpenStreetMap.

27 | 28 |

The icesheet data here essentially contains a set of polygons and 29 | corresponding outlines of the ice-covered areas not explicitly mapped.

30 | 31 |

This is generated by processing the land polygon data and the landcover 32 | mapping of the area from OpenStreetMap with 33 | spatialite. 34 | The processing scripts are available on github as Open 36 | Source.

37 | 38 |

More detailed information can be found 39 | in this blog post.

Rendering example

Here a rendering example from the OpenStreetMap standard style, on the left 44 | without the icesheet polygons, on the right with them - rendered using the same 45 | styling as for normal glaciers.

Processing

7 | 8 |

OpenStreetMap data in its raw form is often hard to use. The goal of this 9 | site is to give you access to pre-processed OSM data in a convenient form. But 10 | we can not create the data in every form that might be needed, so we give you 11 | the background information and the software to do it yourself.

12 | 13 | 14 |

Coastlines

15 |

Coastlines are recorded in OSM using the tag natural=coastline. 16 | Our coastline processing finds all ways with that tag and stitches them 17 | together while correcting small errors.

18 | 19 | 20 | 21 |

Icesheet

22 |

Antarctic icesheets are handled specially: Instead of tagging the ice 23 | sheets, the area in the Antarctic that does not contain any ice is 24 | tagged. Our processing takes this into account when creating icesheet 25 | outlines and polygons.

26 | 27 | 28 | {% comment %} 29 | 30 | 31 |

Generalization

32 |

OpenStreetMap data is amazingly detailed. But for small scale maps (small 33 | zoom levels) this detail is not needed, or worse, cluttering up the map. Our 34 | generalized data removes the detail for nicer looking overview maps.

35 | 36 | 37 | 38 |

Waterbodies

39 |

Waterbody data in OpenStreetMap has a very large volume so for rendering 40 | small scale maps (small zoom levels) we offer a reduced, more compact version 41 | of this that allows rendering the global waterbodies in an efficient way 42 | at these scales.

43 | 44 | 45 | {% endcomment %} 46 | 47 | 48 |

Software

All the software we base our processing on is Open Source. Feel free 50 | to use it, learn from it, and change it.

Waterbody reduction

7 | 8 |

Inland waterbodies in OpenStreetMap are mapped with a variety of tags 9 | producing a fairly large volume of data - more then 5GB of data in usual GIS 10 | formats for the polygon data alone. Since there is no objective measure of 11 | importance for these different features there is no easy way to filter from 12 | this large volume of data only those features that are relevant for rendering 13 | maps at coarse scales.

14 | 15 |

Therefore most OpenStreetMap based maps render water at the low zoom levels 16 | either from other data sources or using questionable filtering techniques that 17 | often lead to low quality results.

18 | 19 |

The reduced waterbody data we offer here is generated from the full set of 20 | waterbody data in OpenStreetMap and reduces this in volume without subjective 21 | decisions that affect the rendering results in undesirable ways. This is done 22 | by rasterizing the data at high resolution and generating a supersampled low 23 | resolution raster mask from it. This raster mask is made available as raster 24 | images and converted back to a very compact polygon representation which is 25 | made available as well.

26 | 27 |

This approach comes with a number of limitations that need to be kept in 28 | mind when using this data:

29 | 30 |
    31 |
  • The files are only suited for rendering in the resolution they are 32 | produced for. Rendering either in a higher or lower resolution will 33 | produce suboptimal results.
    • 34 |
  • The polygon version does not have any topological similarity with the 35 | original data as you might expect. The rivers for example do not form a 36 | continuous geometry.
    • 37 |
  • The styling you can use with these files is somewhat limited. You cannot 38 | render the polygons with an outline for example. Using fill patterns or edge 39 | color gradients should however work.
    • 40 |
  • The process does not perform any 41 | geometric generalization.
    • 42 |
43 | 44 |

Technically the reduction process is implemented with Osmium and GDAL. The polygon representation is produced 47 | using a custom vectorization 48 | tool.
