We are using our Part 107 to perform aerial surveys, stockpile inventories, and inspections. We own DJI Phantom 3 and 4 Professionals and use a variety of methods to process the data into high quality georeferenced orthophotos, topo and contour maps, and 3D models compatible with most Autodesk software such as AutoCAD, Civil 3D, Revit, ReCap and more.
