osm-extract extracts features from OpenStreetMap PBF files as GeoJSON.
- Reads
.osm.pbffiles from local disk, no need to run an Overpass API server. - Preserves OpenStreetMap tags as GeoJSON properties.
- Extremely fast, thanks to
github.com/paulmach/osm. - Optionally polygonizes ways and relations, thanks to GEOS.
- Optionally unions all features into a single feature.
