GIS and geology
Geologists use GIS every day in a wide variety of applications. You too can use GIS to study geologic features, analyze soils and strata, assess seismic information, or create 3-dimensional displays of geographic features. The examples below illustrate some of the ways geologists are using GIS.
You can use GIS to

Assess the Morphology for an Area
|
The Geological Survey of Austria uses a GIS to create a 3-dimensional display of the Glocken region. Using this technique you can easily see the slope, aspect, relative elevation, and watershed for the region as parts of an integrated unit.

Analyze Soils
|
As a geologist you can use GIS to show the distribution of soils as well as
the associated geologic structures.
The Federal Republic of Germany uses GIS to show the different soil types for
the new German states (formerly East Germany).

Assess Seismic Risk
|
Seismologists at the U.S. Geological Survey use GIS to assess the potential
damage from earthquakes.
These maps show the severity and frequency of earthquakes for the lower
Wabash River valley. After the data are displayed, geographic relationships
between the earthquakes and known areas of liquefaction can be used to determine
the overall hazards for any site.
