2002/2003 IfSAR data for Southern California: Digital Elevation Model (NAVD88)

This metadata document describes the collection and processing of topographic elevation point data derived from Interferometric Synthetic Aperture Radar (IfSAR) measurement for coastal Southern California. Collection consists of topographic elevations from the California counties of Santa Barbara, Ventura, Los Angeles, Orange, and San Diego, and the hydrologic units within those counties that drain to the Pacific Ocean along with offshore islands within the Channel Islands. The resulting data available for download, include the Digital Elevation Model (DEM), and the Raw magnitude radar reflectance data. Height Variance data is available upon request from NOAA OCM. The elevation data is first surface return (vegetation is in the dataset) X-band IfSAR with three meter point spacing and approximately one meter vertical accuracy in non-vegetated areas. The elevation data is available in NAVD88 vertical datum.
