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
- 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
Other codes can be found on epsg.org, epsg.io and other sites.
使用法
{{#epsg:x,y,z|source coordinate reference system|target coordinate reference system}}
- Conversion from coordinates x,y,z to an other coordinate reference system{{#epsg_2wgs84:x,y,z|source coordinate reference system}}
- Conversion from other coordinate reference system to WGS84 Latitude, Longitude, Height{{#wgs84_2epsg:latitude , longitude , height|target coordinate reference system}}
- Conversion from WGS84 Latitude, Longitude, Height to an other coordinate reference system
Default coordinate reference system is EPSG:4326 - WGS 84.
{{#epsg:4.88352559,52.37453253,0||7415}}
{{#epsg:4.88352559,52.37453253,0|4326|7415}}
{{#epsg:4.88352559,52.37453253||7415}}
{{#epsg:4.88352559,52.37453253|4326|7415}}
{{#wgs84_2epsg:52.37453253,4.88352559,0|7415}}
{{#wgs84_2epsg:52.37453253,4.88352559|7415}}
All give the same values, approximately: 120701,487525,-43
{{#epsg:120701,487525,-43|7415}}
gives, approximately: 4.88351, 52.3745, 0{{#epsg_2wgs84:120701,487525,-43|7415}}
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.
インストール
- Downloadして、ファイルを
extensions/
フォルダー内のEPSG
という名前のディレクトリ内に配置します。 - 以下のコードを LocalSettings.php ファイルの末尾に追加します:
wfLoadExtension( 'EPSG' );
- 完了 – ウィキの「Special:Version」に移動して、拡張機能が正しくインストールされたことを確認します。
設定
Optionally, you can set the base URL used for the conversion.
$wgEPSG_URL= ''; default: "https://epsg.io/trans"
You can use a server that runs the code from github.com/maptiler/epsg.io.
