A seamless, high-resolution, coastal digital elevation model (DEM) for Southern California

Metadata Updated: November 12, 2020

A seamless, three-meter digital elevation model (DEM) was constructed for the entire Southern California coastal zone, extending 473 km from Point Conception to the Mexican border. The goal was to integrate the most recent, high-resolution datasets available (for example, Light Detection and Ranging (Lidar) topography, multibeam and single beam sonar bathymetry, and Interferometric Synthetic Aperture Radar (IfSAR) topography) into a continuous surface from at least the 20-m isobath to the +20-m elevation contour.

Access Constraints Use Constraints: Majority of data (that is, Lidar, multibeam bathymetry, IfSAR) derived from topographic/bathymetry data collected at 1-3 m horizontal resolution,with vertical uncertainty at time of data collection ranging from 10 cm to 1 m, Use at greater scales not advised.
