Indoor navigation system: walking directions on your own floor plans

In the read-only viewer, and on share links, a Navigate button sits at the bottom-left of the map (“Get directions between two points”). Click a start, click a destination, and Spatial Map draws a green walking route with turn-by-turn steps in a Directions panel. In the editor the same tool is Route from A to B, which doubles as a layout check: a “No path found” usually means a door is missing.

Under the hood, Spatial Map lays a grid of 25 cm squares over the floor, marks each square open or blocked from what is drawn — walls and racks block, doors open — and searches for the shortest walkable path (A*), with a small cost per turn and a preference for the middle of corridors. Details are in the wayfinding docs.

Being precise about the limits is what makes it easy to deploy:

Many projects need more: a visitor app with multi-floor routes, step-free options, a blue dot from beacons, or a kiosk that starts from where it stands. Those are built on top of the same map as a custom development project — the building is already mapped, so the work is the routing between floors, the positioning and the app. Positioning hardware is covered on hardware and BLE asset tracking.

For the trade-offs between signage, kiosks, apps and blue dot in busy public buildings, read indoor wayfinding for airports and malls; the turn-by-turn directions guide shows the built-in feature step by step.
