The Geologic Atlas of Texas is now online and available at your fingertips!

In October 2002, the USGS Texas Water Science Center, in cooperation with the Texas Natural Resources Information System, embarked on a project to digitize all 38 Geologic Atlas of Texas hardcopy map sheets and compile them into a single, stand-alone database. Completed in 2007, the project resulted in a rich, digital dataset containing more than 145,000 geologic features in Texas and portions of neighboring states.

Launch the Viewer

In 2014, the USGS Texas Water Science Center decided it was time to bring the Geologic Atlas of Texas to the masses by developing a comprehensive online viewer. From the USGS:

USGS example of the GAT ViewerThe new map viewer is an interactive web-based tool that allows a broad range of users to explore the geology of the Lone Star State at a scale of 1:250,000. Users can navigate the map with a simple click-and-point tool, or by using the location search tool to find common geographic place names, latitude/longitude coordinates and other areas of interest. The interactive map viewer allows users to turn data layers on or off, identify layers of interest and retrieve detailed information about each geologic formation, such as the feature name, geologic age and feature description.
