The gridded DEM surface estimates the elevation of the land surface at mid-day low-tide on 10 July, 2017 in the Braddock Bay West study area. It was created to demonstrate the use of structure-from-motion (SfM) for shoreline research and to provide a means to measure the accuracy of the elevation measured through SfM photogrammetry. It is released to provide an elevation dataset that is more accessible than the LAZ elevation point cloud for the general user.
