The current GeoJSON spec. [1] mentions in the abstract, as last of its containing three sentences: "GeoJSON uses a geographic coordinate reference system, World Geodetic System 1984, and units of decimal degrees.".
[2] contains an update which says "2008 geojson.org GeoJSON supported alternative coordinate reference systems other than ESPG:4326, but this capability was removed in the current GeoJSON standard." So, it seems, that QGIS is actually following the 2008 spec. and probably should be updated. => Someone files an issue? --Stefan 1] https://tools.ietf.org/html/rfc7946 [2] https://macwright.org/2015/03/23/geojson-second-bite 2017-11-22 21:37 GMT+01:00 C Hamilton <[email protected]>: > I don't know, but if that it the case then QGIS is exporting GeoJSON wrong. > For example if you have a layer that is say EPSG:3857 and export the points > to a GeoJSON file, you will find a crs tag specifying 3857 and the > coordinates are in 3857.
