I am currently undertaking a project attempting to explore how morphology along the Holderness Coast, England, has changed over time. I have LiDAR tile data from 2001 - 2017 all at 2m spatial resolution (DTM and DSM) and LiDAR point cloud data from 2008 - 2017. I have tried to use surface creation tools such as 'Slope' and 'Cut-Fill' etc but have not had great results. Ideally I would like to quantify the change in sediment volume over the time but not sure what is the best way to go?
Currently I have created a fishnet that overlays LIDAR data set, then calculated the change height for each zone in the grid but i feel there is a more sophisticated analysis which I could undertake?
