Summary
Description
The digital data set provides point locations and general descriptions of areas photographed to document sites visited during a study to refine current estimates of ground-water discharge from the major discharge areas of the Death Valley regional flow system. Photographs were taken 1994-99. Sites were used as controls to better improve the delineation of ET (evapotranspiration) units classified using spectral methods throughout each of the major discharge areas.
