Mount Washington Nevada 3D GIS

This 3D GIS view of Mount Washington and surrounding country in the Great Basin National Park in eastern Nevada was created for The Long Now Foundation, to show the location of their 10,000 year Clock on the Foundation's property just south of Mount Washington. The Landsat7 Satellite image from 2000 has been draped over a USGS DEM (Digital Elevation Model)allowing the image to be seen in three dimentions. In addition, an 1873 map of the same area made by the Wheeler Survey can be blended into the 3D view to see how the area has changed over time.

The flash movie below gives a preview of the 3D GIS experience. Click on the link below the flash movie to launch the full 3D Mount Washington GIS Viewer, but READ this first - the 3D GIS Viewer has three viewing modes: Inspection (opening mode), Fly Through, and Hover. Use the space bar to toggle between them. Use your mouse and arrow keys for Fly-Through, arrow keys and page up/down for Inspection, and arrow keys and "1" key (down) and "2" key (up) for Hover. Using keys together will produce different motions. The key row Z,X,C,V,B will blend between the Landsat7 image and the 1873 historical map. Detailed Help is available.

Launch times will vary depending on your connection. For a DSL line, the first time you launch the 3D Viewer, it will take about 30 seconds to install and open the image; subsequent viewing will only take about 5 seconds to open the file since it is stored in your browser's cache. With a modem, the first launch will take from 10-20 minutes. The Virtools Web Player should download automatically when you launch the 3D GIS Viewer. If it does not, you can download it here. Windows 95/98/ME/2000/NT4.0/XP, MAC OSX (beta).
