Aerial mapping using drones is undertaken using photogrammetry, using a series of still photographs rather than moving video. Photogrammetry is the science of creating measurements from photographs, and the result is normally a map, 2D or 3D model of a building, structure or object. The process of creating the map or model is done using specialist software and accurate measurements of things like length, area and volume can be derived from the map or model.
There are numerous applications of aerial drone mapping. They include in the construction industry when assessing the progress of a development, or in the water industry when mapping and sizing a water reservoir. Aerial mapping with UAV's is also ideal when inspecting a solar farm where we can use aerial maps to spot any issues with the solar panels using infrared cameras.
