Classification of evapotranspiration units in major discharge areas of Death Valley regional flow system, Nevada and California
Listed in NASA Earthdata CMR
The data set was created to delineate the aerial extent and quantify acreage of the different ET units found within the many major discharge areas of the Death Valley regional flow system.
Description
The raster-based classification of evapotranspiration (ET) units is for nine major discharge areas in the Death Valley regional flow system. The ET units delineate general areas of similar vegetation and soil-moisture conditions.
Classifications were derived from Landsat Thematic Mapper imagery data acquired June 13, 1992; Sept. 1, 1992; and June 21, 1989. Introduction The raster-based classification of ET units within the major discharge areas of the Death Valley regional flow system determined from Landsat Thematic Mapper (TM) imagery data acquired June 13, 1992, Sept. 1, 1992; and June 21, 1989. Background information on classification procedures can be found in American Society of Photogrammetry (1983).

Except for Sarcobatus Flat, all discharge areas were classified using the 1992 TM imagery. An accurate classification of Sarcobatus Flat could not be attained from 1992 TM imagery because of extensive cloud cover over the area. Instead, Sarcobatus Flat was classified from TM data acquired June 21, 1989.
Reviews The final classification of ET units within each major discharge area was checked for consistency and accuracy during data processing. Two external reviews were done. The reviewers were asked to check metadata and other documentation files for completeness and accuracy.
Reviewers also were asked to check the topological consistency, tolerances, projections, and geographic extent.
