Geograph MN is the edition of the popular GIS (geographic information system) covering the state of Minnesota. 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 Land of Ten Thousand Lakes. With the iPhone's GPS, it enables you to navigate the state and get a much better understanding of your surroundings, identify geological formations, mines, quarries, rivers, etc....

This release contains 27 layers, which can be combined in any desired way:

Each layer contains additional information about each feature. 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.
