Major GIS Data Clearinghouses
This page contains links to additional GIS datasets and information not certified or maintained by TCEQ. All links will take you off the TCEQ Web server . Many of the GIS layers found at these sites are in a projection other than TSMS. Also, the file format and spatial coverage area will vary from layer to layer. Some of the layers do not have metadata. If available, access the metadata to determine the projection parameters, spatial extent, and other important information. Because the TCEQ has no control over the posting of material to the sites on this list, the agency cannot take responsibility for their continued validity and maintenance.
