How to use GeoJSON for Chad
- geojson.io — drag the file into a browser window and see the features on the map right away, clicking to inspect properties.
- QGIS (free) — Layer → Add Vector Layer, choose the .geojson.
- Leaflet / Mapbox GL JS / OpenLayers — put the file next to your project and hook it up: in Leaflet that is L.geoJSON(data).addTo(map), in Mapbox GL a source of type geojson.

FAQ: GeoJSON for Chad
Can I open GeoJSON in a browser?
Yes, on geojson.io or any web app with Leaflet/Mapbox.
Is GeoJSON a free format?
Yes — the format itself is open (RFC 7946), and exporting to it on OSM2CDR is free. There is only one limitation, a technical one: 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.
