TxGIO (Texas GIS)

No authtx-txgio

TxGIO — Texas Geographic Information Office (formerly TNRIS), the state GIS clearinghouse, via its public ArcGIS REST services (feature.geographic.texas.gov). Statewide Texas base GIS as map-ready WGS84 GeoJSON: incorporated city boundaries (1,225), legislative districts (TX Senate/House + US Congressional), 1:250k geology (units/faults/dikes), NHD hydrography (rivers/streams + waterbodies), and StratMap land parcels (~14.3M). Complements the Texas connectors rrc (O&G wells), tceq (environmental), twdb (water wells), and tx-glo (state lands) with the statewide base layers none of them carry. No auth.
