The smoothed shoreline is based on the NOAA Continually Updated Shoreline Products (CUSP) found at: http://shoreline.noaa.gov/data/datasheets/cusp.html. The shoreline from Point Conception to LA Harbor was smoothed with a window of 400 m in ArcGIS 10.2.2. The smoothed shoreline was splited in 82 segments (ID range 1 to 82) and for each segment a buffer distance in meters was recorded in the attribute table (dist_buff column).

The data were derived from the shoreline published by NOAA Continually Updated Shoreline Product (CUSP) http://shoreline.noaa.gov/data/datasheets/cusp.html that was smoothed with a 400 m window in ArcGIS 10.2.2. An ID was provided and a buffer distance expressed in meters. The ID and buff_dist columns are part of the new shapefile attribute table.
Seacliff erosion is a serious hazard with implications for coastal management, and is often estimated using successive hand digitized cliff tops or bases (toe) to assess cliff retreat. Even if efforts are made to standardize manual digitizing and eliminate subjectivity, the delineation of cliffs is time consuming, and depends on the analyst’s interpretation. We propose an automatic procedure to extract cliff edges from high resolution lidar-derived bare-earth digital elevation models, generalized coastal shoreline vectors and approximate measurements of distance between the shoreline and the cliff top. The method generates orthogonal transects and profiles with a minimum spacing equal to the digital elevation model...
