Geology ID

Geology ID is the Idaho version of the first GIS (geographical information system) for the iPhone.

Unlike Google Maps, Geology ID 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).

Geology ID contains a selection of geographical information in its internal database. It can display this information in 29 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.

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

Geology ID can also generate high-resolution maps that you can download to your computer. The following is a combination of the terrain and annual precipitation layers (difficult to believe it was actually generated on an iPhone, isn't it?):
