TxGIO (Texas GIS)

Free

TxGIO — Texas Geographic Information Office (formerly TNRIS), the state GIS clearinghouse, through public ArcGIS REST services. Runs on PatchOps' shared ArcGIS engine and returns WGS84 GeoJSON for incorporated cities, legislative districts, 1:250k geology, NHD hydrography, and StratMap parcel polygons. The parcel MapServer is exposed through bounded service-level identify queries with typed filters and truncation disclosure. Complements rrc, tceq, twdb, and tx-glo. No auth.
