Another highly sophisticated and useful drone aerial service and application is the 3D mapping via Photogrammetry of any given area, structure, artefact, building to collect hundreds of geo-referenced photos. By processing the data collected a 3D model, orthophoto, orthomosaic map, DSM, DTM, Contour lines map and any other kind of product can be generated via special software, and be exported to any kind of format, such as DWG, BIM, GIS, etc. to be further processed.
