*2.2. DEM Skill Assessment*

To verify the accuracy of the DEMs generated from the terrain dataset, the DEMs from the study area were compared to those already generated by NOAA and provided in the public domain. Specifically, the datasets from 2015 were compared by extracting beach profiles from each R-monument and plotting them into Excel, where profile graphs could be generated and overlaid with one another to compare the accuracy of the data to that of DEM's generated by NOAA. The two datasets showed very good agreement across all of the R-monuments down the study area, confirming the reliability of the approach and the accuracy of the DEM development [11].
