What if you could hold all of Texas in the palm of your hand?
Geology TX is
the Texas version of the first GIS (geographical information system) for the iPhone.
This initial release focuses on the geology of Texas, and related data.
Unlike Google Maps, Geology TX 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.
HOW DOES IT WORK?
Geology TX 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.
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 an area of the Geology layer brings up a screen similar to the following:
With Geology TX, you can finally access data that is relevant to you
without needing access to a computer or a network.
Tools
• Distance
• Area
• GPS position
• Screen capture
• Equidistant circles
• Lon/lat grid
Geology TX can also generate high-resolution maps that you can download
to your computer. The following is a combination of the states outline, bathymetry,
elevation, and main aquifers layers (difficult to believe it was actually generated
on an iPhone, isn't it?):
