I have 2 layers of points in the point cloud. The upper layer have detail of the terrain such as roads and mine pits, but much less points than the layer below. The lower layer has much more detail, however it seems to terminate (last image), with the upper layer continuing to cover a majority of the survey area.
How do I deal with cleaning this up? Add mtp and reprocess, or delete the upper layer where there is overlap and re-run step 3?
