Moving Features JSON (MF-JSON)
“Moving Features JSON” is a standard for encoding moving features in JSON. By using MF-JSON, rather than some other arbitrary scheme, you maximize the interoperability of your JSON output. MF-JSON is an Open Geospatial Consortium standard, which extends the GeoJSON standard.
