How to use our Mapping App

Click on the link or the map to go to the Mapping App.

Click the "Find address or place" field. Here you can enter the name of a town, a latitude/longitude or a 911 address. Or of course you can just navigate to your area of interest. Type in the name of Voca, TX for example... Or enter a lat/long: " 31.0000 -99.000 [enter]"

As long as the Well Data for Website layer is turned on, you can learn more about individual wells. Click on any of the wells (dots) for a popup with more information. There's a link at the bottom of each popup that will take you to a log.

The legend for the wells is under the basemap options as long as the "Wells Data" layer is turned on.

Surface Geology is available from the Geologic Atlas of Texas. Toggle it on...

This layer depicts the Geology closest to the surface.

Click on an area to find out the formation is.

In the lower right hand corner there is a GAT filter where you can choose a formation and the map will only depict that formation. A dropdown is available. Choose the Formation you'd like to see and then turn on the Filter Gat toggle button.

Faults can also be loaded.

Turning off Surface Geology makes these easier to see faults but often you want both depicted simultaneously.

Depth to the top of the Hickory is a very useful tool. Contour lines are labeled but also respond to a click with a popup.
