Cliff edges are compiled by state and generally correspond to two periods: 1920s-1930s and 1998-2002. Each cliff edge may represent a compilation of data from one or more sources for one or more dates provided by one or more agencies.

The original data from ATM was collected in WGS 84, ITRF 97, in a geographic (lat/long) coordinate system with irregular spacing. The data was then converted to NAD 83 and NAVD 88. The cliff edge generation involved an analysis of shore-normal profiles at 20m intervals alongshore. The point solutions were connected to produce a continuous vector cliff edge in shapefile format. A shore-parallel reference line was digitized as a permanent baseline for any future cliff edge generation.
