OGC API – Moving Features over MobilityDB via PyMEOS
A Python implementation of the OGC API – Moving Features standard served over MobilityDB through PyMEOS: collection and feature CRUD, MovingFeature and FeatureCollection responses, user-supplied temporal properties, an NDJSON and Parquet lakehouse export feed, bulk fleet-feed ingest, vendored MEOS-API artefacts, an HTTP server, tutorial notebooks, and a test suite.
