Abstract
Satellite imagery was obtained for approximately 1.2 million acres on the remote Great Rift Zone of the Central. Snake River Plain. Using an analytical technique, large-scale land patterns were determined by cluster analysis at a scale of 1:24,000. Field examination of previously selected cluster sample points was done to obtain a correlation of soil surfaces, miscellaneous land types and vegetation species to various reflectance values recorded by the satellite camera. Upon computer analysis of the cluster point sample data, a level of similarity was determined and classes selected for the major land and vegetation patterns. This data is currently being applied to a low order standard soil survey in the area. Its usefulness as a "tool" in generating a general soils map, preliminary mapping, and mapping unit design has helped personnel map this remote area with a higher degree of accuracy and confidence.
