Pop-ups most likely will have to be disabled or set to be allowed for The South Texas Map. Many add on tool bars have pop-up blockers in them as well. There are hyperlinks to information contained in the map, to outside web pages and to the print routine that may be treated by your system as a pop-up. If nothing happens when one of these is clicked on the problem is most likely a pop-up blocker.

Screen Resolution

Your resolution settings will greatly effect the quality of the map displayed. Viewing the maps in less than 1024x768 resolution is not recommended and we strongly suggest using much higher resolution whenever possible.


We recommend using Firefox. Every effort was made to make the map display the same in Firefox & Internet Explorer but there are differences. If you have Firefox already please use it for viewing The South Texas Map. If you don't, download it & try it. It's free, more secure & you might just like it.

The Map, Map Speed & Feedback

The South Texas Map is a GIS (Geographic Information System) application. GIS is a powerful mapping program for displaying database information in map form. GIS applications display maps in an infinite number of ways using colors and layers. The benefits of GIS technology are huge and the calculations performed to display the map are also huge. Because of everything that has to be done to display each map view it will take a few seconds to load. Please be patient when using The South Texas Map. Hundreds of hours were spent (just ask our wives) to make the map draw as fast as possible but because of what it can do it's going to take a few seconds. No, it's not as fast as Google Maps or others, but the others don't have the accuracy nor the information The South Texas Map has. We welcome your comments & suggestions, from which an FAQ will be developed. Please let us know how we can make it better for you & what we can add to it. The map will be continuously updated. We welcome any suggestions you may have. Please email your suggestions or corrections by clicking here
