Service-area analysis for cities and councils

Model who can reach what, where the gaps are, how transit changes the answer. Reachability and matrix tools for civic planning.

Public-sector planning runs on accessibility analysis. Where can residents reach the library, the GP, the leisure centre on foot or by bus inside 15 minutes? Which neighbourhoods sit outside every walking isochrone? How does adding a new bus route shift the answer?

Footstep ships the reachability and matrix tools that those analyses depend on. get_isochrone draws walk-time, cycle-time, and drive-time polygons. get_matrix builds the OD grids that feed accessibility scores. get_elevation surfaces terrain for infrastructure planning where grade matters (cycle networks, accessible routes).

All outputs are versioned and GeoJSON-ready, so commissioning teams can drop them into ArcGIS, QGIS, or web dashboards without a transformation step.

Patterns

What this looks like in practice

Common shapes mapped to the tools you'd reach for.

15-minute neighbourhood mapping

For every residential parcel, compute a 15-minute walking isochrone. Intersect with categories like schools, GPs, libraries, and parks. Score parcels on category coverage to surface gaps.

Transit-change impact

Compute walk-time matrices to bus stops before and after a route change. Quantify population shifted in or out of the 30-minute access band.

Accessible-route planning

Use get_elevation along candidate cycle routes to identify segments above the gradient threshold for accessibility. Feed back into the network design.
