The ultimate app for Geography/Geology amateurs and professionals."

- Mel Martin, TUAW.com

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:

- states outlines

- the complete geological map from USGS

- surficial materials

- terrain elevation

- zip codes

- over 2, 200 named features (summits, tunnels, cliffs, bridges, etc...)

- annual precipitation

- glacial limits

- U.S. congressional districts

- over 2, 300 mineral resources

- active mines

- old faults

- public land ownership

- hydrologic units

- EPA ecological regions

- USGS quadrangles

- township and range

- urban areas

- counties

- hydrology

- roads and major streets

- railroad tracks

- cities and towns

- over 200 potassium/argon dates

- state plane zones

- UTM zones

- main aquifers

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.

There have been a few improvements since the release of the sister programs covering CA, TX, NY/NJ/CT, FL, WA/OR, AZ, CO, UT, NV, NM, ID, MT and WY.

5/5 stars

Interesting and fun to use

I've been zooming around the state lately and I look forward to using this. The collection of layers seems reasonable, I kind of wish there were more (especially e.g. wildlife management areas for us hunters). But this is a very cool app.

5/5 stars

I'm excited about this app

Minnesota usually doesn't get a lot of attention, so it's nice to see a lovely, well thought-out app like this. It contains many interesting layers such as a geological map, roads, railroads, counties, etc... and you can overlay them on top of each other with transparency. It's really interesting and fun to use, and I'm showing it to all my friends and colleagues.

5/5 stars


A must for rock hounds metallurgists or amateur explorers
