Drone aerial survey
Drone topographic surveys, orthophoto maps, photogrammetric 3D models and aerial construction monitoring, tied to ground control points measured by GNSS RTK.
Drone aerial surveys capture large areas quickly and collect data from hard-to-reach or hazardous sites without sending people in. Photogrammetric processing produces orthophotos with a ground pixel size of a few centimetres, dense point clouds, digital terrain models and 3D models of structures. Because ground control points are measured by GNSS RTK, results are accurately tied to the national coordinate system and can be used directly in topographic, design and mine survey work.
As a surveying company, Topoqraf AZ treats drone imagery as a measurement method rather than just pictures: the flight plan is calculated for the required accuracy, results are checked against control points, and an accuracy report is provided. Flights are carried out in line with current regulations and with the necessary permits.
Below you will find drone topographic surveys, orthophoto map production, photogrammetric 3D models, aerial photo and video monitoring of construction, engineering drone video and aerial surveys for inventory.
