GIS Data

 
GIS data is available by clicking on the Map Library Link below, in the form of downloadable zipped shapefiles. If you need data that is not available for download, please submit an Open Records Request. The requested information will be sent no later than 10 business days.

These downloads require the use of a GIS data viewer. ESRI provides a free viewer, ArcExplorer, available for download at http://www.esri.com/software/arcgis/explorer-desktop/download. Some of the features are very large and may take several minutes to download. All files are NAD 83 State Plane Texas South Central.
