iPhone GIS application for Texas

Integrity Logic announced the release of Geology TX, the Texas version of the GIS (Geographic Information System) for the iPhone platform. This initial release focuses on the physical geography and geology of Texas, and contains 21 layers of information, which can be superimposed, mixed and rearranged in any desired combination.

Like its sister application Geology CA, which covers California, Geology TX contains a number of data layers which can be combined and moved in any desired way:

• geological map from the U.S. Geological Service
• states outline of Texas and adjacent states
• land elevation from NASA
• ocean bathymetry from NOAA
• all 92 Texas earthquakes in recorded history with a magnitude of 3.0 or greater
• recent and ancient faults
• county lines, USGS quadrangles
• UTM zones, state plane zones
• urban areas, hydrological features
• cities, roads and railroad tracks
• active mines and quarries
• all available potassium/argon dates
• vegetation zones
• river basins
• main aquifers

Geology TX is a completely self-contained application, which does not require any Internet access. This is critical for anyone who needs access to this information when out of cellular range, in the field. Geology TX can use the iPhone's built-in GPS and the iPod's location service, and can also capture high-definitions maps, which can be retrieved from the device's photo album. The application is available immediately in the Apple App Store and is priced for a limited time at $4.99.
