Hi, I’m trying to calculate the volume of various areas of beach using point cloud data. I want to calculate it above a horizontal plane at a level input as a user parameter and I have individually references mif/mid polygons demarking the areas.
I have been using the method at the below link as a starting point, but the problem is the beach is sloping, not flat, meaning using the z.median value gives an incorrect result.
Any suggestions for a solution would be gratefully recieved!
