Visualizing Hospital Accessibility with OpenStreetMap
summary
Interactive static-site maps show driving-time isochrones to the nearest hospital computed entirely from OSM using Valhalla for isochrones, Python + rasterstats to weight by the EU Global Human Settlement population raster, and vector tiling with ProtoMaps and MapLibre GL. Results: Virginia shows about 65% of people within 10 minutes and ~99% within 40 minutes; North America build is ~1 GB while the Virginia build is 12 MB, hosted on GitHub Pages and Cloudflare R2. Psychiatric hospitals are filtered out and Alaska’s Aleutians are excluded.
