The Texas statewide city boundary dataset is one component of the Texas Strategic Mapping Program (StratMap) political boundary layers. The StratMap program developed seven digital base map layers for Texas. StratMap is managed by the Texas Natural Resources Information System (TNRIS), a division of the Texas Water Development Board (TWDB). All data produced through StratMap are available in the public domain. The data sources for each city polygon vary. Sources used were the Texas Department of Transportation data and local data from the council of governments or its component governments. The attribute coding scheme is designed to accommodate several basic cartographic data categories such as feature type, feature name, jurisdiction entity, data source used in feature collection, data source date and revision date(s) if applicable. |
