Google Earth Geothermal Maps

GreatBasinGeothermal.kmz (download)

We are experimenting with Google Earth as a platform for spatial geothermal data. Google Earth has several advantages compared with our ArcIMS interactive maps, including (1) extraordinary pan, zoom, and rotation capability, (2) the option to view the ground from any angle, and (3) great aerial photos draped on top of good DEM's.

There are also a few drawbacks: the increased run-time once GIS layers are loaded and the limited symbology / lack of legend. We included a short legend for our Google Earth geothermal data below. Click here for more information as to how the favorability map was produced.

Legend for the Google Earth data:

Above: Vertical Google Earth view of the Dixie Valley geothermal system, with locations and values of temperature gradient data.

Below: Horizontal Google Earth view of Dixie Valley, looking northeast.

USGS_Quat_Flts: Quaternary faults from the USGS Quaternary fault database: faults in red have estimated offsets > 0.3 mm/year, those in black < 0.3 mm/year.

SMUwells: Temperature gradient data from Dave Blackwell at Southern Methodist University and John Sass of the U.S.G.S. Warmer colors have higher values; values are shown. The "No_Data" file shows wells with no temperature gradient data.

Geothermal Favorability: A qualitative version of the Great Basin Center's geothermal favorability map, with warm colors representing areas of higher favorability. Click here for additional information.
