FAQ: GeoJSON for Dédé

Can I open GeoJSON in a browser?

Yes, on geojson.io or any web app with Leaflet/Mapbox.

How much does a GeoJSON export cost?

The format itself is open (RFC 7946). Export is priced per map area, the same for every format; you see the price before paying. A technical rule also applies: the larger the area, the coarser the detail, so that the file stays a workable size.

Can I load GeoJSON into PostGIS?

Yes, via ogr2ogr or directly with SQL functions like ST_GeomFromGeoJSON.

How do I split the export back into layers?

All the layers arrive in one FeatureCollection, but every feature has a service property _layer — roads, buildings, water, green_areas and so on. Filtering on that field in QGIS, Leaflet or GeoPandas splits the file into separate layers in a single line.

Which projection do the coordinates arrive in?

WGS84 (EPSG:4326) — plain latitude and longitude, as the GeoJSON specification requires. Nothing needs reprojecting for the web or for GIS; if your project is run in a metric system, the conversion is done on the QGIS or PostGIS side.
