Digital Elevation Models (DEMs) are digital records of
terrain elevations at regularly spaced intervals. The
interval between elevations of 7.5 minute DEMs is
30-meters. Each DEM file covers the area of one U.S.
Geological Survey 1 to 24,000 scale 7.5 minute
topographic quadrangle.
DEMs can be used for creation of slope maps, aspect
maps, shaded relief maps, and contour maps, for analysis
of hydrography and runoff. For this dataset, the original
ArcInfo Grid of the San Gorgonio Pass and surrounding
area in Riverside County, California was clipped to produce
accurate elevation data for calculations in hydrologic
applications.

Not applicable for raster data.
The source dataset was originally created displaying
elevation values in meters. The new grid was created with
elevation values in feet.
The original source grid provided elevation values in
meters. This new grid was produced to provide elevation
values in feet. The procedure used to alter the units were
to multiply the DEM in meters by the meters to feet
conversion constant of 3.280839895.
