"The ultimate app for Geography/Geology amateurs and professionals."
- Mel Martin, TUAW.com
Do you know which state assembly district you are in? Which school district? Where is the closest railroad? Is there a mine nearby? What kind of rock are you sitting on?
Geograph GA is the edition of the popular GIS (geographic information system) covering the state of Georgia. It is a self-contained application (no Internet or cellular access required) that contains a vast amount of information about the geography and geology of the Peach State. You can combine various data layers, zoom in and out, and get a lot of details about the physical and human geography of Georgia.
While this is a professional-grade tool, it can easily be used by anyone curious about their environment.
This release has 40 layers (and new layers are frequently added). Installed by default are:
- states outlines
- the complete geological map from USGS
- surficial materials and faults

Each layer contains additional information about its features. For instance, the geology layer has a description of the unit's name, age range, rock type, and description. Each mine has a name, a commodity, a facility type, and a company name. See our web site for more information about each layer. Layers can be re-ordered and combined with transparency, allowing an unlimited number of combinations.
