Build a wildfire-evacuation map for a Sacramento-area community, then compute its routes to safety, all on your laptop. One open pipeline runs from DuckDB and Overture through Planetiler tiles and MapLibre to live OSRM routing.

A planet-scale tile generation architecture from multiple sources, built entirely with open-source frameworks. We showcase how distributed geospatial processing (Apache Sedona, Planetiler) cut worldwide generation time from 31 hours to 3 and eliminated ~$50K/month in database costs.
