Matrix — Geospatial Distance Matrix

Matrix is the hardened version of Distances — same core concept but built for repeated, structured use. It runs in locked production mode, meaning the core matrix calculation engine is stable and doesn't change session-to-session.

What it does

Add locations via a management panel. The map plots all points. The matrix view calculates every location-to-location pair: driving distance and duration, rendered in a scrollable grid.

Use Distances for quick one-off lookups. Use Matrix when you're managing a fixed set of locations across multiple sessions.
