7 tools

• list_boundary_type_codes

  Returns every valid UK boundary type code mapped to its human-readable label. Call this before using any tool that accepts a `boundary_type` or `boundary_types` argument so you know which codes are legal. Passing an unlisted code to another tool raises a ValueError. Boundary ty

• search_boundaries_by_name

  Search for UK administrative boundaries by name (case-insensitive partial match). Use this to discover boundaries when you have a place name but not a code. Returns lightweight metadata only — no geometry. If you need to display or analyse the boundary shape, call get_boundary_g

• find_boundaries_at_point

  Find all UK administrative boundaries that geographically contain a coordinate point. Use this to answer "what county/borough/ward is this location in?" for a latitude/longitude. Returns lightweight metadata only — no geometry. If you need to display a boundary shape, call get_b

• get_boundary_by_code

  Look up metadata for a single UK boundary by its ONS census code. No geometry. Use this when you already have a census code (e.g. from search_boundaries_by_name() or find_boundaries_at_point()) and need structured metadata such as area size or type label. If you also need the bo

• get_boundary_geojson_by_code

  Fetch the full GeoJSON geometry for a UK boundary by its ONS census code. Returns a GeoJSON Feature object (WGS-84 / EPSG:4326) suitable for rendering on a map or performing geometric analysis. The geometry can be large — county and ceremonial county polygons are especially heav

• get_boundary_geojson_simplified

  Fetch simplified GeoJSON for a boundary by its ONS census code. Safe to embed directly in generated HTML map files. At the default tolerance (0.0001°) a constituency polygon shrinks from ~4,000 vertices to ~200–400 with no visible difference at normal map zoom levels. Prefer th

• get_boundary_bbox

  Get the bounding box and centroid for a boundary by its ONS census code. Returns min_lat, max_lat, min_lng, max_lng, centroid_lat, centroid_lng. Pass the bbox values directly to Knotsure's sightings_in_bbox() or geographic_summary(). Much cheaper than get_boundary_geojson_by_cod
