USAtlas Geology

iOS Universel / Education

US GEOLOGY is one of the twelve chapters of The National Atlas of the United States® which was coordinated and lead by USGS, this is the effort of more than 20 Federal agencies. The other layers are, Agriculture, Biology, Boundaries, Climate, Environment, Government, History, Map Reference, People, Transportation and Water. Geobyte is planning to produce these Chapters in future.

In this volume we have incorporated 46 layers of vector information available at The National Atlas of the United States® Website. These include Earthquakes, Volcanoes, Geologic Map, Mineral Operation, Magnetic Field, Waterways, County Boundaries and many more.

Detailed Geologic Maps (scale of 1:500,000 or larger) and Faults, from Open-File Reports of USGS of 48 States are also included.

The Legend or Key for each layer has been designed in the way that one can select all or select specific units from the legend and generate the map of particular interest. For example you can generate map with only Cretaceous Sedimentary rocks and only earthquakes of certain magnitude.

The units on the map can be identified by long tap on the map.

With the GPS capability of the system the location on the ground is known and you can add, edit and save notes on the map.The distance between two points and the area of polygon can also be calculated.

All the layers can be displayed in both Mercator and Lambert Equal-Area Projections.

There is no need to have access to WIFI, 3G or 4G Data Network to use this app. All the data are saved in your device.
