Extension:EPSG

The EPSG extension allows the conversion of coordinates to various coordinate systems using the EPSG Geodetic Parameter Dataset.

This extension is a MediaWiki front end for the conversion done by epsg.io.

Common EPSG codes
Other codes can be found on epsg.org, epsg.io and other sites.
 * EPSG:4326 - WGS 84, latitude/longitude coordinate system based on the Earth's center of mass, used by the Global Positioning System among others.
 * EPSG:3857 - Web Mercator projection used for display by many web-based mapping tools, including Google Maps and OpenStreetMap.
 * EPSG:7789 - International Terrestrial Reference Frame 2014 (ITRF2014), an Earth-fixed system that is independent of continental drift.
 * EPSG:7415 - Amersfoort / RD New + NAP height

Usage
Default coordinate reference system is EPSG:4326 - WGS 84.
 * - Conversion from coordinates x,y,z to an other coordinate reference system
 * - Conversion from other coordinate reference system to WGS84 Latitude, Longitude, Height
 * - Conversion from WGS84 Latitude, Longitude, Height to an other coordinate reference system

All give the same values, approximately: 120701,487525,-43


 * gives, approximately: 4.88351, 52.3745, 0
 * gives, approximately: 52.3745, 4.88351, 0

The extension is not dependent, but works best with the Semantic MediaWiki, Maps and Arrays extensions.

Planned features

 * The possibility of using a self-hosted server with code from https://github.com/maptiler/epsg.io.
 * Special page "EPSGTest" (Special:EPSGTest) provided by this extension to give an overview of example use cases and their expected results.
