Measurement

Surveying by drone

Drone photogrammetry creates current, high-resolution images of the surface from the air. These images can be used to calculate 3D models from the image data and create 2D maps. The data sets show areas in their current condition and are higher resolution than satellite images. This method also offers a positional accuracy of 1 cm – 2 cm and a height accuracy of 2 cm – 3 cm.
