The Advantages

Photogrammetry UAV Survey/Aerial Mapping photography for mapping purposes using drones, compared to other vehicles such as manned aircraft or satellites has several advantages:

  1. Drones can be easily deployed for projects in certain areas, compared to the mobilization process required when using manned aircraft.
  2. Drones are very suitable for mapping with small to medium areas and have a much smaller minimum order compared to manned aircraft or satellites. Then, by using drones, the operational costs incurred are smaller. Finally, the drone can be operated at low altitudes (below 1,500 feet) to avoid clouds and to obtain higher image resolution.

Through the use of UAV photogrammetry and lidar mapping, the following surveys can be carried out:

  • DEM / DTM / DSM (surface model)
  • 3D Building Models
  • Contour Map (DTM)
  • Planimetric features (roadside, heights, signs, building footprints, etc.)
  • Volumetric Survey

Example of a ground control point where drones are needed to provide pinpoint accurate positioning for highly detailed missions
