osm-lump-ways group OSM ways based on topology & shared tagsAnswer questions about OSM data like:
- “What's the longest Main Street?”
- “How far can I drive on unpaved roads in this region?”
- “How long is the M1 motorway?”
- “Are these rivers connected?”
- “What's the river drainage basins?”
Generate river drainage basins
osm-lump-ways -i path/to/region-latest.osm.pbf -o region-rivers.geojson -f waterway=river
To group based on the river's name:
osm-lump-ways -i path/to/region-latest.osm.pbf -o region-rivers.geojson -f waterway=river -g name
To find long streets and assemble them into connected (Multi)LineStrings:
osm-lump-ways -i path/to/region-latest.osm.pbf -o region-rivers.geojson -f highway -g name
cargo install osm-lump-ways
OSM linear features (eg roads, rivers, walls) are stored as way
object. The OSM tagging
model often requires one feature to
be mapped as many different ways. osm-lump-ways will assemble them all together.
