The first step our team takes after initial processing of drone data is to compare the actual point cloud to control and other conventionally surveyed items (EP, FL, TBC, etc..). This site we just flew is looking great, with control and field topo shots measuring well under a tenth when compared to the drone data. The data looks good, now it's time to build a surface from the point cloud and deliver a ready to use CAD file containing a TIN surface and planimetric linework at our survey clients standard layers.
