What the file carries

The GeoJSON file for Manono: the whole map comes as a single file, the file is plain text and opens in any editor, all features lie in one collection, and the source layer name stays in the _layer field, OpenStreetMap tags are kept as feature attributes.

File size

The expected size of the GeoJSON file for Manono is about 921 KB; the exact size depends on the chosen layers and area.

GeoJSON file passport

Estimated from the place's OSM data; exact figures are in the file after the build.

Layers: 2
Features by geometry type (estimated): points 1, lines ≈ 0, polygons 413
Most common tags of the place: building=residential 346, building=religious 8, convenience 1

Losses: nothing to lose.

Build recipe: GeoJSON (RFC 7946): one FeatureCollection for all layers, WGS 84 (EPSG:4326), 6 decimal places in coordinates, frame 2.4 × 2.3 km, geometry not simplified; OSM tags → properties.

How to use GeoJSON for Manono

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 Manono

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.
