Extension:EPSG/de-formal

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.

There is a special page "EPSGTest" (Special:EPSGTest) provided by this extension to give an overview of example use cases and their expected results.

Configuration
Optionally, you can set the base URL used for the conversion.

You can use a server that runs the code from github.com/maptiler/epsg.io.
