Tracking OpenStreetMap History and Quality with the ohsome Stack
summary
The ohsome stack exposes a time-indexed OpenStreetMap history via the OSM history database (OSHDB) and web APIs, with a form-based dashboard that shows concrete metrics — e.g., manatee-tagged features in Virginia grow from ~50k to ~120k over nine years and healthcare features show linear growth with a 2017 dip. A hex-aggregated explorer reveals cities hitting 100% emergency-tagged hospitals in 2018 before a decline. A combined intrinsic/extrinsic QA layer and a real-time change stream support comparisons to footprints/population and event-triggered updates (routing, HOT stats).
