Geology UT

What if you could hold Utah in the palm of your hand?

Geology UT is the Utah version of the first GIS (geographical information system) for the iPhone.

This initial release focuses on the geology of the Beehive state, and related data.

Geology of Utah
Unlike Google Maps, Geology UT is completely self-contained, which means that it is always available, even without any cellular or wireless coverage. It can be used in the field, in the middle of nowhere. It can of course take full advantage of the iPhone's built-in GPS receiver (this is more limited on the iPod).
Terrain, public lands and hydrology around Salt Lake City
Geology UT contains a selection of geographical information in its internal database. It can display this information in 25 different layers. Each layer can be individually shown or hidden, moved up or down, and made more or less transparent. This allows an almost infinite number of possible displays.
Terrain, zip codes and roads east of the Great Salt Lake

Each feature of most layers has additional information which can be displayed by tapping the feature. This brings up a list of all the data in all the displayed layers at that point.

The user can then select the desired layer and get all the available information. For instance, tapping a data point in the Geology layer brings up a screen similar to the following:

With Geology UT, you can finally access data that is relevant to you without needing access to a computer or a network.

Geology UT can also generate high-resolution maps that you can download to your computer. The following is a combination of the terrain, roads, and urban areas in eastern Utah (difficult to believe it was actually generated on an iPhone, isn't it?):
