I need a complete digital Aufmaß of several buildings located just north of Hamburg, captured entirely by drone. The goal is to generate material accurate enough for reliable surface and volume calculations, façade and roof measurements, and future renovation planning. Because precision is essential, all aerial photos have to be delivered in high resolution; please plan your flight path, altitude, and overlap accordingly to guarantee crisp, distortion-free imagery. After the flights I expect you to handle the full photogrammetric workflow—image alignment, dense point cloud generation, mesh/texturing, and creation of an orthomosaic or georeferenced point cloud that I can load directly into CAD software. Please also export the raw photo set so I have an untouched reference. Indicate which drone platform and processing software (e.g. DJI, Pix4D, Agisoft Metashape) you intend to use, your typical ground sampling distance for similar jobs, and your estimated turnaround time per building. I will provide exact addresses, take-off points and any air-traffic-related paperwork once we agree to proceed.
