Leaflet GeoJSON

From Maps for MediaWiki

Maps supports working with GeoJSON since version 6.

Since GeoJSON is an open standard, there are many tools that allow you to create an consume GeoJson. A simple online visual map editor that outputs GeoJSON is geojson.io.

GeoJSON files

{{#display_map: center=Berlin
 | geojson = https://raw.githubusercontent.com/leakyMirror/map-of-europe/master/GeoJSON/europe.geojson
}}

In-wiki GeoJSON

Since version 6.0, you can store your GeoJSON in wiki pages that are in the GeoJson namespace. For instance GeoJson:Berlin. You can use this GeoJSON in the #display_map parser function via the geojson parameter, by giving it the page name. The GeoJSON stored in a page can be used by as many maps as you like.

{{#display_map: center=Berlin | geojson=Berlin}}

The pages in the GeoJson namespace make sure they contain valid JSON. Once saved, the pages show a preview of the GeoJSON on a Leaflet map.

Visual editor

Since version 6.7 pages in the GeoJson namespace contain a visual map editor. The editor is only shown to those with permissions to edit the page.

Since version 7.13 the editor is also shown on regular maps that use GeoJson.

Semantic MediaWiki integration

Since Maps version 7.16 there is experimental SMW integration that stores GeoJson data as SubObjects. Contact Jeroen De Dauw for more information.

Limitations

As of version 7.16:

You can hire Jeroen De Dauw (creator of Maps) to work on the above via Professional.Wiki.
