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? Are we in a floodable zone?

Geograph MI is the edition of the popular GIS (geographic information system) covering the state of Michigan. 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 Wolverine State. You can combine various data layers, zoom in and out, and get a lot of details about the physical and human geography of Michigan.

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

- terrain elevation and Great Lakes bathymetry

- zip codes

- over 1, 700 named features (summits, tunnels, cliffs, bridges, etc...) with link to USGS information page

- U.S. congressional districts with link to representatives' web sites

- over 3, 100 mineral resources with link to USGS web site

- active mines

- public land ownership

- hydrologic units

- EPA ecological regions

- 1, 316 USGS quadrangles

- urban areas

- annual precipitation

- counties with link to census data

- hydrology

- roads and major streets

- railroad tracks

- UTM zones and state plane zones

- main aquifers with link to EPA web site

Layers that can be downloaded from the application include:

- state House districts with link to representatives' web sites

- state Senate districts

- elementary and unified school districts

- boundaries of cities and villages with link to census data

- town boundaries

- landmark areas (parks, campgrounds, airports, etc...)

- landmark points (schools, hospitals, fire stations, etc...)

- airports with link to FAA data pages for each airport

- 12, 797 geodetic points with link to the National Geodetic Survey details pages

- national park boundaries with link to the National Park Service web page for each park

- railroad crossings with link to details page from the Federal Railroad Administration

- floodable areas from FEMA (premium content)

- American Indian areas

- land use/land cover

- all roads and streets

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.

These apps are so good that I've ditched all my geology books! And they keep improving. One addition - I'd like to be able to send the maps to my TV.
