Geodetic Drone Surveying (UAV)
Fast aerial surveying of large areas — for orthophoto plans, 3D terrain models, volume calculations, construction monitoring.
What's included
- ✓ Orthophoto plans with accuracy to 2 cm/pixel
- ✓ 3D terrain models (DEM/DSM/DTM)
- ✓ Volume calculations (piles, fills, excavations)
- ✓ Documentation for investors and public
What aerial photogrammetry with drone is
Geodetic drone surveying is a modern method for fast coverage of large areas and high-accuracy 3D terrain modeling. With autonomous flight the drone captures hundreds of photos from various angles, which specialized software combines into:
- Orthophoto plan — geometrically corrected aerial photo with accurate coordinates;
- Digital surface model (DSM) — heights of everything on terrain (ground, buildings, trees);
- Digital terrain model (DTM/DEM) — bare earth only;
- 3D mesh model — for visualization and presentation;
- Point cloud — compatible with laser scanners.
Benefits of drone surveying
- Speed — dozens of decares per flight, while classical survey takes days;
- Safety — no human risk in dangerous zones;
- Access — hard-to-reach terrain, deep excavations, tall structures;
- Multiple uses — one photo set → orthophoto + 3D + volumes + documentation;
- Time-series monitoring — easy flight repetition for progress tracking.
Typical assignments
Geodesy and cadastre
- Surveying large agricultural land for cadastre registration;
- Quick orthophoto refresh for municipalities;
- Survey before PUP for large territory.
Construction
- Monthly large-site surveys — progress tracking;
- As-built documentation for infrastructure objects;
- Pre-construction documentation.
Quarries and fills
- Volume calculations — tonnage extracted/added;
- Monthly reports for investors.

Frequently asked questions
What is drone surveying?
Drone surveying (UAV — Unmanned Aerial Vehicle) is aerial photogrammetry — a series of low-altitude photos processed in specialized software for high-accuracy products: orthophoto plans, digital terrain models, 3D models.
What accuracy does drone surveying achieve?
With properly placed ground control points (GCPs) — 2 to 5 cm in plan and height. With RTK drone and target markers — up to 1 cm.
Are you licensed to fly drones?
Yes. Our operators have all necessary permits from the General Directorate of Civil Aviation Administration (GDCAA) — categories Open and Specific per EASA regulations.
