Data Dictionary

TCLGIS has hundreds of publicly available GIS layers for you to use.  This Data Dictionary is the best way to search for our content.

For a detailed description of each layer, click the “view” link that appears in the table to the right of each layer’s summary. To view each layer on a map, click the “mapit” link at the far right of the table.
