Drone Mapping Services

Photogrammetry to produce terrain maps, topography and ortho images
If you require topographic maps or orthomosaics of your site, we’re here to help. This is because TerraDat has extensive experience creating detailed maps and 3D models from high-resolution imagery combined with precise geomatic survey data. The use of Unmanned Aerial Vehicles (UAV), also known as drones or UAS, equipped with state of the art sensors allows rapid data acquisition over large areas at competitive prices.

Recent years have seen huge developments in drones and processing software. Combined with centimetre-accurate RTK GNSS corrections, we are able to efficiently generate highly detailed deliverables including:

– digital surface models (DSM) and digital terrain models (DTM)
– surface flow maps
– topographic contour maps
– georeferenced RGB point clouds
– complex mesh models of the land surface, buildings, monuments
– incredibly detailed orthophotographs


Efficient grid missions
We use the best available mission planning software to maintain constant flight heights above ground level (AGL), thus ensuring that the GSD (ground sample distance) in pixels per centimetre are maintained. Typical GSD values range from 1.5-3 cm/pixel.

To ensure safety, our aircraft have ultrasonic collision detection systems as well as ADS-B receivers to mitigate risks with nearby manned aircraft.
