Drone Based Survey

A drone survey refers to the use of a drone, or unmanned aerial vehicle (UAV), to capture aerial data with downward-facing sensors. During the survey, the ground is photographed several times from different angles, and each image is tagged with coordinates. From this data, a photogrammetry software can create geo-referenced orthomosaics, elevation models or 3D models of the project area. These maps can also be used to extract information such as highly-accurate distances or volumetric measurements, with all survey data georeferenced.

Unlike manned aircraft or satellite imagery, drones can fly at a much lower altitude, making the generation of high-resolution, high-accuracy data, much faster, less expensive.

Benefits of Drone Surveying

  • Reach difficult terrain and map otherwise inaccessible areas
  • Capture data during operation without disruption.
  • Higher accuracy and exhaustive data, as a drone survey produces thousands of measurements (compared to a total station that only measure
    individual points).
  • Faster turnaround time.
