Morita, A.Y. and Predmore, S.K., 2004, A 30 meter Digital Elevation Model (DEM) of the San Gorgonio Pass area, Riverside County, California: U.S. Geological Survey data release, https://doi.org/10.5066/P9HSN27V.

Summary

These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. 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.

Purpose

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.
