I currently have an aerial photograph of a barrier beach, and corresponding LiDAR data for the 2005 photo, 2007 photo, and 2013 photo.
I want to calculate the volume of sediment on the beach for each year above sea level. There are various guides but I am still confused how to do this for just the area of beach I have, and not the whole area of LiDAR. The LiDAR files are tiff.
I am using ArcMap 10.2.2.
