If you want to help out, log into [OSGeo Weblate](https://weblate.osgeo.org/projects/postgis-workshop/). 23 | 24 | If you don't already have an OSGeo account, [you can get one here](https://id.osgeo.org/ldap/create). An OSGeo account will allow you to participate in translating both the PostGIS workshop and PostGIS documentation as well is several other [OSGeo projects](https://www.osgeo.org/projects/). 25 | 26 | 27 | Translation status 28 | 29 | 30 | ## Building the Workshop Content 31 | 32 | * Install Sphinx: http://www.sphinx-doc.org/en/1.8/usage/installation.html 33 | * python3 -m venv ~/pw-env 34 | * source ~/pw-env/bin/activate 35 | * Go to the source directory: `cd postgis-intro/sources/en/` 36 | * Build the HTML: `make html` 37 | * Check the outputs: `cd ../../doc/en` 38 | 39 | If you get an error about TemplateNotFound('sphinxdoc/layout.html') then 40 | Try doing below (for python3, might need to use pip3 instead of pip): 41 | `pip install sphinx-rtd-theme` 42 | 43 | ##

Small databases will float up entirely into RAM cache, and get away from physical disk limitations, but for large databases, access to the physical disk will be a limiting stop in disk access speed. 7 | 8 | Data is written to disk opportunistically, so there is not necessarily any correlation between the order data is stored on the disk and the way it will be accessed or organized by applications. 9 | 10 | .. image:: ./screenshots/clustering1.jpg 11 | :class: inline 12 | 13 | One way to speed up access to data is to ensure that records which is likely to be retrieved together in the same result set are located in similar physical locations on the hard disk platters. This is called "clustering". 14 | 15 | The right clustering scheme to use can be tricky, but a general rule applies: indexes define a natural ordering scheme for data which is similar to the access pattern that will be used in retrieving the data. 16 | 17 | .. image:: ./screenshots/clustering2.jpg 18 | :class: inline 19 | 20 | Because of this, ordering the data on the disk in the same order as the index can provide a speed advantage in some cases. 21 | 22 | Clustering on the R-Tree 23 | ------------------------ 24 | 25 | Spatial data tends to be accessed in spatially correlated windows: think of the map window in a web or desktop application. All the data in the windows has similar location value (or it wouldn't be in the window!) 26 | 27 | So, clustering based on a spatial index makes sense for spatial data that is going to be accessed with spatial queries: similar things tend to have similar locations. 28 | 29 | Let's cluster our ``nyc_census_blocks`` based on their spatial index: 30 | 31 | .. code-block:: sql 32 | 33 | -- Cluster the blocks based on their spatial index 34 | CLUSTER nyc_census_blocks USING nyc_census_blocks_geom_idx; 35 | 36 | The command re-writes the ``nyc_census_blocks`` in the order defined by the spatial index ``nyc_census_blocks_geom_gist``. Can you perceive a speed difference? Maybe not, because the original data may have already had some pre-existing spatial ordering (this is not uncommon in GIS data sets). 37 | 38 | Disk Versus Memory/SSD 39 | ---------------------- 40 | 41 | Most modern databases are run using SSD storage, which is much faster at random access than old spinning magnetic media. Also, most modern databases are running on top of data which is small enough to fit into the RAM of the database server, and ends up there as the operating system "virtual filesystem" caches it. 42 | 43 | Is clustering still necessary? 44 | 45 | Surprisingly, yes. Keeping records that are "near each other" in space "near each other" in memory increases the odds that related records will move up the servers "memory cache hierarchy" together, and thus make memory accesses faster. 46 | 47 | .. image:: ./screenshots/clustering5.png 48 | :class: inline 49 | 50 | System RAM is not the fastest memory on a modern computer. There are several levels of cache between system RAM and the actual CPU, and the underlying operating system and processor will move data up and down the cache hierarchy in blocks. If the block getting moved up happens to include the piece of data the system will need next... that's a big win. Correlating the memory structure with the spatial structure is a way in increase the odds of that win happening. 51 | 52 | Does Index Structure Matter? 53 | ---------------------------- 54 | 55 | In theory, yes. In practice, no really. As long as the index is a "pretty good" spatial decomposition of the data, the main determinant of performance will be the order of the actual table tuples. 56 | 57 | The difference between "no index" and "index" is generally huge and highly measurable. The difference between "mediocre index" and "great index" usually takes quite careful measurement to discern, and can be very sensitive to the workload being tested. 58 | 59 | 60 | Function List 61 | ------------- 62 | 63 | `CLUSTER `_: Re-orders the data in a table to match the ordering in the index. 64 | -------------------------------------------------------------------------------- /postgis-intro/sources/en/creating_db.rst: -------------------------------------------------------------------------------- 1 | .. _creating_db: 2 | 3 | Creating a Spatial Database 4 | =========================== 5 | 6 | PgAdmin 7 | ------- 8 | 9 | PostgreSQL has a number of administrative front-ends. The primary one is `psql `_, a command-line tool for entering SQL queries. Another popular PostgreSQL front-end is the free and open source graphical tool `pgAdmin `_. All queries done in pgAdmin can also be done on the command line with ``psql``. 10 | pgAdmin also includes a geometry viewer you can use to spatial view PostGIS queries. 11 | 12 | #. Find pgAdmin and start it up. 13 | 14 | .. image:: ./screenshots/pgadmin_01.png 15 | :class: inline 16 | 17 | #. If this is the first time you have run pgAdmin, you probably don't have any servers configured. Right click the ``Servers`` item in the Browser panel. 18 | 19 | We'll name our server **PostGIS**. In the Connection tab, enter the ``Host name/address``. If you're working with a local PostgreSQL install, you'll be able to use ``localhost``. If you're using a cloud service, you should be able to retrieve the host name from your account. 20 | 21 | Leave **Port** set at ``5432``, and both **Maintenance database** and **Username** as ``postgres``. The **Password** should be what you specified with a local install or with your cloud service. 22 | 23 | .. image:: ./screenshots/pgadmin_02a.png 24 | :class: inline 25 | 26 | Creating a Database 27 | ------------------- 28 | 29 | #. Open the Databases tree item and have a look at the available databases. The ``postgres`` database is the user database for the default postgres user and is not too interesting to us. 30 | 31 | #. Right-click on the ``Databases`` item and select ``New Database``. 32 | 33 | .. image:: ./screenshots/pgadmin_02.png 34 | :class: inline 35 | 36 | #.

The difference is due to the linear stroking of the edges of the buffer. The buffer has a finite number of edges. Increasing the number of edges in the buffer will get the value closer to pi, but it will always be smaller due to the linearization. 95 | 96 | * **The Brooklyn neighborhoods of ‘Park Slope’ and ‘Carroll Gardens’ are going to war!

Note that the area of the intersection is in square meters because we are still working in UTM 18 (EPSG:26918). 117 | 118 | :: 119 | 120 | 180990.964207547 121 | 122 | -------------------------------------------------------------------------------- /postgis-intro/sources/en/index.rst: -------------------------------------------------------------------------------- 1 | ..

PostgreSQL for Windows and MacOS either include PostGIS or have an easy way to add it on. 9 | * There are instructions below on how to install `PgAdmin `_. PgAdmin is a graphical database explorer and SQL editor which provides a "user facing" interface to the database engine that does all the work. 10 | 11 | For always up-to-date directions on installing PostgreSQL, go to the `PostgreSQL download page `_ and select the operating system you are using. 12 | 13 | 14 | PostgreSQL for Microsoft Windows 15 | -------------------------------- 16 | 17 | For a Windows install: 18 | 19 | #. Go to the `Windows PostgreSQL download page `_. 20 | 21 | #. Select the latest version of PostgreSQL and save the installer to disk. 22 | 23 | #. Run the installer and accept the defaults. 24 | 25 | #. Find and run the "StackBuilder" program that was installed with the database. 26 | 27 | #. Select the "Spatial Extensions" section and choose latest "PostGIS ..Bundle" option. 28 | 29 | .. image:: ./screenshots/install_windows_01.png 30 | :class: inline 31 | 32 | #.

| 6 | Here's a reminder of the functions we saw in the last section. They should be useful for the exercises! 7 | 8 | * :command:`sum(expression)` aggregate to return a sum for a set of records 9 | * :command:`count(expression)` aggregate to return the size of a set of records 10 | * :command:`ST_Contains(geometry A, geometry B)` returns true if geometry A contains geometry B 11 | * :command:`ST_Crosses(geometry A, geometry B)` returns true if geometry A crosses geometry B 12 | * :command:`ST_Disjoint(geometry A , geometry B)` returns true if the geometries do not "spatially intersect" 13 | * :command:`ST_Distance(geometry A, geometry B)` returns the minimum distance between geometry A and geometry B 14 | * :command:`ST_DWithin(geometry A, geometry B, radius)` returns true if geometry A is radius distance or less from geometry B 15 | * :command:`ST_Equals(geometry A, geometry B)` returns true if geometry A is the same as geometry B 16 | * :command:`ST_Intersects(geometry A, geometry B)` returns true if geometry A intersects geometry B 17 | * :command:`ST_Overlaps(geometry A, geometry B)` returns true if geometry A and geometry B share space, but are not completely contained by each other. 18 | * :command:`ST_Touches(geometry A, geometry B)` returns true if the boundary of geometry A touches geometry B 19 | * :command:`ST_Within(geometry A, geometry B)` returns true if geometry A is within geometry B 20 | 21 | Also remember the tables we have available: 22 | 23 | * ``nyc_census_blocks`` 24 | 25 | * blkid, popn_total, boroname, geom 26 | 27 | * ``nyc_streets`` 28 | 29 | * name, type, geom 30 | 31 | * ``nyc_subway_stations`` 32 | 33 | * name, geom 34 | 35 | * ``nyc_neighborhoods`` 36 | 37 | * name, boroname, geom 38 | 39 | Exercises 40 | --------- 41 | 42 | * **What is the geometry value for the street named 'Atlantic Commons'?** 43 | 44 | .. code-block:: sql 45 | 46 | SELECT ST_AsText(geom) 47 | FROM nyc_streets 48 | WHERE name = 'Atlantic Commons'; 49 | 50 | :: 51 | 52 | MULTILINESTRING((586781.701577724 4504202.15314339,586863.51964484 4504215.9881701)) 53 | 54 | * **What neighborhood and borough is Atlantic Commons in?** 55 | 56 | .. code-block:: sql 57 | 58 | SELECT name, boroname 59 | FROM nyc_neighborhoods 60 | WHERE ST_Intersects( 61 | geom, 62 | ST_GeomFromText('LINESTRING(586782 4504202,586864 4504216)', 26918) 63 | ); 64 | 65 | :: 66 | 67 | name | boroname 68 | ------------+---------- 69 | Fort Green | Brooklyn 70 | 71 | .. note:: 72 | 73 | "Hey, why did you change from a 'MULTILINESTRING' to a 'LINESTRING'?" Spatially they describe the same shape, so going from a single-item multi-geometry to a singleton saves a few keystrokes. 74 | 75 | More importantly, we also rounded the coordinates to make them easier to read, which does actually change results: we couldn't use the ST_Touches() predicate to find out which roads join Atlantic Commons, because the coordinates are not exactly the same anymore.

1 | .. _welcome: 2 | 3 | Welcome 4 | ******* 5 | 6 | Workshop Conventions 7 | ==================== 8 | 9 | These sections conform to a number of conventions to make it easier to follow the conversation. This section gives a brief overview of what to expect in the way of typographic conventions, as well as a short overview of the structure of each workbook. 10 | 11 | Directions 12 | ---------- 13 | 14 | Directions for you, the workshop attendee, will be noted by **bold** font. 15 | 16 | For example: 17 | 18 | Click **Next** to continue. 19 | 20 | Code 21 | ---- 22 | 23 | SQL query examples will be displayed in an offset box 24 | 25 | .. code-block:: sql 26 | 27 | SELECT postgis_full_version(); 28 | 29 | These examples can be entered into the query window or command line interface. 30 | 31 | Notes 32 | ----- 33 | 34 | Notes are used to provide information that is useful but not critical to the overall understanding of the topic. 35 | 36 | .. note:: If you haven't eaten an apple today, the doctor may be on the way. 37 | 38 | Functions 39 | --------- 40 | 41 | Where function names are defined in the text, they will be rendered in a :command:`bold` font. 42 | 43 | For example: 44 | 45 | :command:`ST_Touches(geometry A, geometry B)` returns TRUE if either of the geometries' boundaries intersect 46 | 47 | Files, Tables and Column Names 48 | ------------------------------ 49 | 50 | File names, paths, table names and column names will be shown in ``fixed-width`` font. 51 | 52 | For example: 53 | 54 | Select the ``name`` column in the ``nyc_streets`` table. 55 | 56 | Menus and Form elements 57 | ----------------------- 58 | 59 | Menus/submenus and form elements such as fields or check boxes and other on-screen artifacts are displayed in *italics*. 60 | 61 | For example: 62 | 63 | Click on the *File > New* menu. Check the box that says *Confirm*. 64 | 65 | Workflow 66 | -------- 67 | 68 | Sections are designed to be progressive. Each section will start with the assumption that you have completed and understood the previous section in the series and will build on that knowledge. A single section will progress through a handful of ideas and provide working examples wherever possible. At the end of a section, where appropriate, we have included a handful of exercises to allow you to try out the ideas we've presented. In some cases the section will include "Things To Try". These tasks contain more complex problems than the exercises and is designed to challenge participants with advanced knowledge. 69 | -------------------------------------------------------------------------------- /postgis-intro/sources/jp/Makefile: -------------------------------------------------------------------------------- 1 | # Makefile for Sphinx documentation 2 | # 3 | 4 | # You can set these variables from the command line. 5 | SPHINXOPTS = 6 | SPHINXBUILD = sphinx-build 7 | PAPER = 8 | 9 | # Internal variables. 10 | DOC = ../../doc/jp 11 | PAPEROPT_a4 = -D latex_paper_size=a4 12 | PAPEROPT_letter = -D latex_paper_size=letter 13 | ALLSPHINXOPTS = -d $(DOC)/.build/doctrees $(PAPEROPT_$(PAPER)) $(SPHINXOPTS) . 14 | 15 | .PHONY: help clean html web pickle htmlhelp latex changes linkcheck 16 | 17 | help: 18 | @echo "Please use \`make ' where is one of" 19 | @echo " html to make standalone HTML files" 20 | @echo " pickle to make pickle files (usable by e.g. sphinx-web)" 21 | @echo " htmlhelp to make HTML files and a HTML help project" 22 | @echo " latex to make LaTeX files, you can set PAPER=a4 or PAPER=letter" 23 | @echo " changes to make an overview over all changed/added/deprecated items" 24 | @echo " linkcheck to check all external links for integrity" 25 | 26 | clean: 27 | -rm -rf $(DOC) 28 | 29 | html: 30 | mkdir -p ../../doc $(DOC) $(DOC)/.build/doctrees 31 | $(SPHINXBUILD) -b html $(ALLSPHINXOPTS) $(DOC) 32 | @echo 33 | @echo "Build finished.

ジオメトリを取り扱う際に等値を判別するのはややこしくなりがちです。PostGISは、透明性のためには下記の定義が用いたれますが、異なるレベルの等値を判別する目的の3種類の関数をサポートしています。これらの関数を描くためには、次のようなポリゴンを用います。 10 | 11 | .. image:: ./equality/polygon-table.png 12 | 13 | これらのポリゴンは、以下のコマンドを用いてロードされます。 14 | 15 | .. code-block:: sql 16 | 17 | CREATE TABLE polygons (name varchar, poly geometry); 18 | 19 | INSERT INTO polygons VALUES 20 | ('Polygon 1', 'POLYGON((-1 1.732,1 1.732,2 0,1 -1.732, 21 | -1 -1.732,-2 0,-1 1.732))'), 22 | ('Polygon 2', 'POLYGON((-1 1.732,-2 0,-1 -1.732,1 -1.732, 23 | 2 0,1 1.732,-1 1.732))'), 24 | ('Polygon 3', 'POLYGON((1 -1.732,2 0,1 1.732,-1 1.732, 25 | -2 0,-1 -1.732,1 -1.732))'), 26 | ('Polygon 4', 'POLYGON((-1 1.732,0 1.732, 1 1.732,1.5 0.866, 27 | 2 0,1.5 -0.866,1 -1.732,0 -1.732,-1 -1.732,-1.5 -0.866, 28 | -2 0,-1.5 0.866,-1 1.732))'), 29 | ('Polygon 5', 'POLYGON((-2 -1.732,2 -1.732,2 1.732, 30 | -2 1.732,-2 -1.732))'); 31 | 32 | SELECT Populate_Geometry_Columns(); 33 | 34 | .. image:: ./equality/start13.png 35 | 36 | 完全等値 37 | ^^^^^^^^^^^^^ 38 | 39 | 完全等値は、二つのポリゴンについて、位置が同じであることを確認するために、頂点を順に比較することで決定されます。以下の例は、この手法が有効性においてどう制限されることがあるかを示してます。 40 | 41 | .. code-block:: sql 42 | 43 | SELECT a.name, b.name, CASE WHEN ST_OrderingEquals(a.poly, b.poly) 44 | THEN 'Exactly Equal' ELSE 'Not Exactly Equal' end 45 | FROM polygons as a, polygons as b; 46 | 47 | .. image:: ./equality/start14.png 48 | 49 | この例では、ポリゴンはそれぞれ自身に等しいのみで、その他の外見は同等なポリゴン（Polygon 1から3の例）とは等しくありません。Polygon 1,2,3の場合、頂点は位置は同一ですが、順序が異なっています。Polygon 4はPolygon 1と同等でなくなるような、六角形の辺の上に同一線上で冗長な頂点があります。 50 | 51 | 空間等値 52 | ^^^^^^^^^^^^^^^ 53 | 54 | 上で見たように、完全等値はジオメトリの空間的性質を考慮しません。ジオメトリの空間的な等値あるいは等価を試すために、`ST_Equals`と適切に名付けられた関数があります。 55 | 56 | .. code-block:: sql 57 | 58 | SELECT a.name, b.name, CASE WHEN ST_Equals(a.poly, b.poly) 59 | THEN 'Spatially Equal' ELSE 'Not Equal' end 60 | FROM polygons as a, polygons as b; 61 | 62 | .. image:: ./equality/start15.png 63 | 64 | これらの結果は、等値の直感的な理解に合致しています。Polygon 1から4は同じ領域を閉じているため等値と見なされます。ポリゴンが描かれる方向、ポリゴンを定義するための始点、点の数は、ここではいずれも重要ではありません。重要なことは、ポリゴンが同じ空間を含んでいると言うことです。 65 | 66 | 等値境界 67 | ^^^^^^^^^^^^ 68 | 69 | 完全等値は最悪の場合、等値を判別するためにジオメトリのすべての頂点を比較することを必要とします。これは時間がかかりますし、ジオメトリの膨大な数の比較を行うには適切でないこともあります。スピーディな比較をするためには、等値境界演算子の、`=`が用意されています。この演算子はバウンディングボックス（矩形）上のみで、ジオメトリが同じ二次元の範囲を専有している（しかし同じ空間の必要はありません）ことを確認しながら動作します。 70 | 71 | .. code-block:: sql 72 | 73 | SELECT a.name, b.name, CASE WHEN a.poly = b.poly 74 | THEN 'Equal Bounds' ELSE 'Non-equal Bounds' end 75 | FROM polygons as a, polygons as b; 76 | 77 | .. image:: ./equality/start17.png 78 | 79 | ご覧のように、すべての空間的に等値なジオメトリは等値な境界を持ちます。残念ながら、Polygon 5も、この試験では等値を返します。なぜならそれは同一のバウンディングボックスをその他のジオメトリとして共有しているからです。では、これは使い物になるのでしょうか。この答えは後ほど詳しく説明しますが、手短に答えますと、この演算子によって、データの結合やフィルタリングを行う際に、膨大な比較セットを管理しやすいブロックに低減するという、空間インデックスの利用が可能となります。 80 |

``nyc_census_blocks`` を使って以下の問いに答えてください。（答えがわかっても声に出しちゃだめですよ。） 7 | 8 | 演習を始める前に、役に立つ情報を整理しておきましょう。 9 | まずは`データについて`の章の``nyc_census_blocks``テーブルの定義です。 10 | 11 | .. list-table:: 12 | :widths: 20 80 13 | 14 | * - **blkid** 15 | - すべての統計**block**を一意に特定するための15桁のコード 例：360050001009000 16 | * - **popn_total** 17 | - その統計ブロックの合計人口 18 | * - **popn_white** 19 | - その統計ブロックの「白人」と自己認識する人口 20 | * - **popn_black** 21 | - その統計ブロックの「黒人」と自己認識する人口 22 | * - **popn_nativ** 23 | - その統計ブロックの「アメリカ原住民」と自己認識する人口 24 | * - **popn_asian** 25 | - その統計ブロックの「アジア民族」と自己認識する人口 26 | * - **popn_other** 27 | - その統計ブロックのその他の民族と自己認識する人口 28 | * - **hous_total** 29 | - その統計ブロックの世帯数 30 | * - **hous_own** 31 | - その統計ブロックの持ち家数 32 | * - **hous_rent** 33 | - その統計ブロックの借家数 34 | * - **boroname** 35 | - ニューヨークの区名（Manhattan, The Bronx, Brooklyn, Staten Island, Queens） 36 | * - **the_geom** 37 | - その統計ブロックのポリゴン境界 38 | 39 | 40 | もうひとつは、よく使われる便利な集約関数です。 41 | 42 | * avg() - レコードの値の平均値を返します 43 | * sum() - レコードの値の合計値を返します 44 | * count() - レコードの数を返します 45 | 46 | さて問題です。 47 | 48 | * **"ニューヨーク市の人口は何人でしょうか？"** 49 | 50 | .. code-block:: sql 51 | 52 | SELECT Sum(popn_total) AS population 53 | FROM

**AS** 句を使って ``population`` というわかりやすい名称に置き換えています。 62 | 63 | * **"ブロンクス区（The Bronx）の人口は何人でしょうか？"** 64 | 65 | .. code-block:: sql 66 | 67 | SELECT Sum(popn_total) AS population 68 | FROM

-------------------------------------------------------------------------------- /postgis-intro/sources/jp/welcome.rst: -------------------------------------------------------------------------------- 1 | .. _welcome: 2 | 3 | ようこそ 4 | ******* 5 | 6 | OpenGeoについて 7 | ============= 8 | 9 | `OpenGeo `_ は、世界中の政府・自治体およびその他の団体へオープンソースソフトウェア導入の成功事例を提供しています。 10 | 11 | * 充分な吟味とサポートの上に統合化された企業向けオープンソースソリューションを提供し、開かれた政府を支援しています。 12 | * PostGIS, GeoServer, GeoWebCache, GeoExt, OpenLayersの主要開発者を擁し、オープンソースコミュニティーをサポートしています。 13 | * MassGIS, Tri-Met, Landgate, Google, The Work Bank, Open Geospatialコンソーシアムといったクライアントへのコンサルティングサービスにおいて8年の実績を持ちます。 14 | * オープンでアクセスしやすい情報は変革を後押しすると考えます。OpenGeoの目標は、広く一般にアクセスでき、また、必要とされている環境で利用できるようにすることで、地理空間情報をもっとオープンにすることです。 15 | * 私たちの市場の成功こそが私たちの業績の価値を証明するものであることから、クライアントの要望を満たすとともに、さらにその上をいくソフトウェアを構築するよう尽力しています。 16 | 17 | OpenGeoは、 `OpenPlans `_ の地理空間部門であり、ニューヨークにおいて、記事やオープンソースソフトウェアを通じ、コミュニティーへ参加・情報提供を行う501(c)(3)非営利団体です。 18 | 19 | ワークショップにおける記述ルール 20 | ==================== 21 | 22 | 各章は、いくつかの記述ルールに従って書かれています。このセクションで、書式の概要と各ワークブックの大まかな構成を簡単に説明します。 23 | 24 | 操作 25 | ---------- 26 | 27 | ワークショップ参加者に実行してもらう操作は、**太字** フォントで表わします。 28 | 29 | 例: 30 | 31 | **Next** をクリックして次へ進みます 32 | 33 | コード 34 | ---- 35 | 36 | SQLクエリーのサンプルは、以下のような囲みで表わします。 37 | 38 | .. code-block:: sql 39 | 40 | SELECT postgis_full_version(); 41 | 42 | これらのサンプルはクエリーウィンドやコマンドラインで入力します。 43 | 44 | note 45 | ----- 46 | 47 | note（補足）は、有用な情報を提供するものでありますが、トピックの全体的理解に必須ではない場合に用います。 48 | 49 | .. note:: もし今日リンゴを食べていないならば、病気になるかもしれない。 50 | 51 | 関数 52 | --------- 53 | 54 | 文中に定義されている関数名は、 :command:`太字` フォントで表わします。 55 | 56 | 例: 57 | 58 | :command:`ST_Touches(geometry A, geometry B)` は、両ジオメトリの境界が交差するときにTRUEを返します。 59 | 60 | ファイル名、テーブル名、フィールド名 61 | ------------------------------ 62 | 63 | ファイル名、パス、テーブル名、フィールド名は、 ``固定幅`` フォントで表わします。 64 | 65 | 66 | 例: 67 | 68 | ``nyc_streets`` テーブルの ``name`` フィールドを選択してください。 69 | 70 | メニューとフォーム要素 71 | ----------------------- 72 | 73 | フィールドまたはチェックボックスといったメニューおよびサブメニュー、フォームの構成要素は、*斜体*で表わします。 74 | 75 | 例: 76 | 77 | *File > New* メニューをクリックしてください。 *Confirm* と書かれたチェックボックスをクリックしてください。 78 | 79 | ワークフロー 80 | -------- 81 | 82 | 各章は順次進行していく形をとっています。前の章を完了し理解したものとして、次の章を進めていきます。いずれの章も、いくつかアイディアを通し、また、できるだけ実行サンプルを示しながら進めていきます。各章の最後には、提供したアイディアを試すことができるよういくつかの演習を含めています。一部の章では、"課題"を設けています。これらは演習で扱ったものよりさらに複雑な問題が含まれており、もっと学びたいという上級者用に作られています。 83 | -------------------------------------------------------------------------------- /postgis-intro/sources/locale/README: -------------------------------------------------------------------------------- 1 | Translation files for the postgis-intro workshop 2 | 3 | Compilation of the files require the ``pip install sphinx-intl`` python3. 4 | 5 | To build localized refer to the README.md in root. 6 | 7 | Using Weblate 8 | --------------- 9 | 10 | Weblate web-ui for translation is at: 11 | https://weblate.osgeo.org/projects/postgis-workshop/ 12 | 13 | There is a web-hook `https://weblate.osgeo.org/hooks/github/` defined in https://github.com/postgis/postgis-workshops/settings/hooks that pushes changes to weblate. 14 | 15 | Weblate does require that the pot files be kept up to date. 16 | To do so: 17 | 18 | ``` 19 | #if using python virtual env 20 | python3 -m venv ~/pw-env 21 | 22 | cd postgis-intro/sources/en 23 | make pot 24 | #test the translations 25 | LANG=ja make html-translation 26 | LANG=sv make html-translation 27 | LANG=de make html-translation 28 | LANG=es make html-translation 29 | LANG=it make html-translation 30 | git add . 31 | git commit -m "Update pots" 32 | git push 33 | ``` 34 | 35 | The github account osgeoweblate has commit rights to this repo. 36 | Any translations that pass approval in the weblate https://weblate.osgeo.org/projects/postgis-workshop/ get pushed and automatically committed. 37 | 38 | The postgis.net, has a cronjob that runs every 5 minutes or so checking for updates and runs this script `/var/www/postgis_workshop_update.sh` if any changes. This builds the main english and all the translations. If new translations are added, then this script needs to be updated to build them. 39 | 40 | Respective docs currently set to build are as follows: 41 | 42 | * English: https://postgis.net/workshops/en/postgis-intro/ 43 | * German: https://postgis.net/workshops/de/postgis-intro/ 44 | * Japanese: https://postgis.net/workshops/ja/postgis-intro/ 45 | * Swedish: https://postgis.net/workshops/sv/postgis-intro/ 46 | * Italian: https://postgis.net/workshops/it/postgis-intro/ 47 | * Spanish: https://postgis.net/workshops/es/postgis-intro/ 48 | -------------------------------------------------------------------------------- /postgis-intro/sources/locale/de/LC_MESSAGES/about_data.mo: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/postgis/postgis-workshops/ac1e67a2a6a14f4bca9319422df92be3520c5569/postgis-intro/sources/locale/de/LC_MESSAGES/about_data.mo -------------------------------------------------------------------------------- /postgis-intro/sources/locale/de/LC_MESSAGES/geography_exercises.po: -------------------------------------------------------------------------------- 1 | # SOME DESCRIPTIVE TITLE. 2 | # Copyright (C) 2012, Paul Ramsey | Mark Leslie 3 | # This file is distributed under the same license as the Introduction to 4 | # PostGIS package. 5 | # FIRST AUTHOR , 2021. 6 | # 7 | #, fuzzy 8 | msgid "" 9 | msgstr "" 10 | "Project-Id-Version: Introduction to PostGIS 1.0\n" 11 | "Report-Msgid-Bugs-To: \n" 12 | "POT-Creation-Date: 2023-01-07 21:46-0500\n" 13 | "PO-Revision-Date: YEAR-MO-DA HO:MI+ZONE\n" 14 | "Last-Translator: FULL NAME \n" 15 | "Language-Team: LANGUAGE \n" 16 | "Language: \n" 17 | "MIME-Version: 1.0\n" 18 | "Content-Type: text/plain; charset=UTF-8\n" 19 | "Content-Transfer-Encoding: 8bit\n" 20 | "Generated-By: Babel 2.9.1\n" 21 | 22 | #: ../../en/geography_exercises.rst:4 23 | msgid "Geography Exercises" 24 | msgstr "" 25 | 26 | #: ../../en/geography_exercises.rst:6 27 | msgid "" 28 | "Here's a reminder of all the functions we have seen so far.
