California shorelines and shoreline change data, 1998-2016

January 19, 2021

This data release contains mean high water (MHW) shorelines along the coast of California for the years 1998/2002, 2015, and 2016, extracted from Light Detection and Ranging (LiDAR) digital elevation models using ArcGIS. The Digital Shoreline Analysis System (DSAS) was used to calculate net shoreline movement (NSM) between the pre-El Nino (2015) and post-El Nino (2016) shorelines, as a proxy for sandy shoreline change throughout the El Nino winter season. For a longer-term perspective of background shoreline behavior, end-point rates (EPR) of change were also calculated between the 1998/2002 and the 2016 shorelines.
