What is the Geothermal Information Layer, release 2, for Oregon?

With the GTILO-2 web map you can view information on location, temperature, and other features of thermal springs and wells (geothermal exploration, geothermal test, and water wells) as well as direct-use areas. GTILO-2 data are currently accessible as ArcGIS Viewer for Flex interactive map data, Excel spreadsheets, compressed (zipped) .shp files including metadata, and PDFs.

What do I need to use the map viewer?
