It is written entirely in PHP and 2 | can therefore run on shared hosts. It can read and write a wide variety of formats (WKT, WKB, GeoJSON, 3 | KML, GPX, GeoRSS). It works with all Simple-Feature geometries (Point, LineString, Polygon, GeometryCollection etc.) 4 | and can be used to get centroids, bounding-boxes, area, and a wide variety of other useful information. 5 | 6 | geoPHP also helpfully wraps the GEOS php extension so that applications can get a transparent performance 7 | increase when GEOS is installed on the server. When GEOS is installed, geoPHP also becomes 8 | fully compliant with the OpenGIS® Implementation Standard for Geographic information. This means that 9 | you get the full-set of openGIS functions in PHP like Union, IsWithin, Touches etc. 10 | 11 | Applications get a useful "core-set" of geometry operations that work in all environments, and an "extended-set" 12 | of operations for environments that have GEOS installed. As time and resources allow we will be porting as much as 13 | possible to native PHP to enable more operations on hosts without GEOS. 14 | 15 | See the 'getting started' section below for references and examples of everything that geoPHP can do. 16 | 17 | This project is currently looking for co-maintainers. If you think you can help out, please send me a 18 | message. Forks are also welcome, please issue pull requests and I will merge them into the main branch. 19 | 20 | Getting Started 21 | ----------------------- 22 | 23 | * The lastest stable version can always be downloaded at: 24 | * Read the API Reference at: 25 | * Examples 26 | * Using geoPHP as a GIS format converter: 27 | * Other Interesting Links: 28 | * Learn about GEOS integration at: 29 | 30 | Example usage 31 | ------------------------------------------------- 32 | 33 | include_once('geoPHP.inc'); 34 | 35 | // Polygon WKT example 36 | $polygon = geoPHP::load('POLYGON((1 1,5 1,5 5,1 5,1 1),(2 2,2 3,3 3,3 2,2 2))','wkt'); 37 | $area = $polygon->getArea(); 38 | $centroid = $polygon->getCentroid(); 39 | $centX = $centroid->getX(); 40 | $centY = $centroid->getY(); 41 | 42 | print "This polygon has an area of ".$area." and a centroid with X=".$centX." and Y=".$centY; 43 | 44 | // MultiPoint json example 45 | print "
