I have a point cloud I am trying to classify, however the classify ground yields poor results. It seems that within my point cloud every point has a return of "x of 3", the only points classified as ground are 3 of 3, whereas areas of unobstructed ground are not classified, and on inspection they have a return of 1 of 3. I believe their return should be 1 of 1, and this is potentially why the tool is not classifying correctly. This seems like this could be an issue with the sensor not recording all this information.
Does this seem like the cause of the problem, and does anyone have a way to work around this? Or extract the correct number of returns from each pulse?
Thanks
