What Is Drone
Topographical Survey?
Drone topographical survey is precision aerial mapping that creates detailed 3D models of terrain, elevations, and landscape features.
Using photogrammetry and GPS technology, we capture thousands of overlapping images to generate contour maps, DTMs, and orthomosaics accurate to 2-3cm - perfect for construction planning, volumetric calculations, and land development.

Common Questions
Everything you need to know about drone topographical surveys
What accuracy can I expect?
Professional RTK/PPK systems achieve 2-5cm horizontal and vertical accuracy with proper ground control points and methodology.
What deliverables are included?
Standard deliverables include contour maps, DTM/DSM, orthomosaics, point clouds, and CAD-ready files in your preferred format.
How large an area can be surveyed?
Coverage depends on accuracy requirements and terrain. Typically 50-200 hectares per day with appropriate flight planning.
Do I need ground control points?
GCPs improve accuracy significantly. Pilots can advise on placement or work with your surveyor for optimal results.
What about vegetation and buildings?
Photogrammetry captures surface models. For bare earth models under vegetation, LiDAR may be more suitable.
Can this replace traditional surveying?
Drone surveys complement traditional methods. Many projects benefit from combining both approaches for comprehensive data.
