Introducing Galaxy: Open Spatial Data Outputs Platform
summary
HOTOSM launches OSM Galaxy (April 2021) as a single site for OSM outputs and already runs a C++ pipeline called Underpass that ingests minutely OSM change files and writes three stores: raw geometry, per-user statistics and a validation table for geometry/tag issues. A FastAPI Galaxy-API exposes those stores with Python and Node clients, and a beta website serves a mapathon leaderboard via OSM login. Current status: raw data and mapathon stats are live, validation and more endpoints remain WIP; code is on GitHub.
