What's in it
- Data offered docs-verified
- buildings · roads · amenities (POI) · waterways (rivers, lakes, canals, reservoirs) · green spaces (parks, forests, farmland, grass, meadow) · railways (rail, subway, tram, stations, platforms) · raw OSM data download via Overpass QL · OSM to GeoJSON conversion
- Coverage llm-inferred
- Global (per ENTRY regions); DOCS examples are Tokyo-only
- Formats docs-verified
- GeoJSON (.geojson/.json file output) · JSON (raw Overpass output via download_osm_data) · XML (raw Overpass output via download_osm_data)
- Access docs-verified
- Local install (npm install, then npm start or register with Claude Code as an MCP server); free; queries public Overpass API; server code under MIT licence; OSM data licence not stated in DOCS
Useful for
- Use cases llm-inferred
- FRA baseline: watercourses and waterbodies within a site bounding box via get_waterways · BNG habitat baseline screening: green spaces (forest, meadow, grass, farmland) as desk-based land-cover context · Site context mapping: roads and railways for access and noise-source screening · Drainage strategy: building footprints in a catchment bounding box for a rough impermeable-area estimate
- Audience llm-inferred
- flood consultants · hydrologists · drainage engineers · ecologists · planners · GIS analysts
Limitations
- Constraints docs-verified
- DOCS recommend use only for education, research and non-profit purposes; commercial consultancy use needs checking against OSM and Overpass usage terms · Recommended bounding box 0.005° × 0.005° or smaller (about 500 m); maximum 0.001 square degrees to avoid timeouts; building queries are costlier than road queries · DOCS recommend no more than 1 request per second; results cached for 15 minutes (TTL) · Depends on public Overpass API servers with a 3-server fallback; availability not guaranteed · DOCS examples and performance figures are Tokyo-only; UK coverage and data quality not documented · Last changelog entry is v1.1.0 dated 2025-07-08; maintenance activity uncertain as of 2026-10 · ENTRY tools field lists input_path, output_path and query, which are parameter names, not tool names · OSM attribution and ODbL obligations not addressed in DOCS
