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

- Mel Martin, TUAW.com

Geology ID is the edition of the popular GIS (geographic information system) covering the state of Idaho. It is a self-contained application (no Internet or cellular access required) that contains a vast amount of information about the geology and geography of the Gem State. Using 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 29 layers, which can be combined in any desired way:

- states outlines

- the complete geological map from USGS

- terrain elevation

- zip codes

- over 6,000 named features (summits, tunnels, cliffs, bridges, etc...)

- fire history

- annual precipitation

- all 966 earthquakes in recorded history over 3.0 magnitude

- seismic hazard

- over 10,000 mineral resources

- active mines

- quaternary faults

- old faults

- public land ownership

- fire risk

- hydrologic units

- EPA ecological regions

- USGS quadrangles

- township and range

- urban areas

- counties

- hydrology

- roads and major streets

- railroad tracks

- cities and towns

- over 700 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.

Although this is a professional-quality tool, it can be used by anyone interested in their environment.

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 and NM. A new layer (fire risk) has been added.
