Using survey-grade drones we provide high-resolution orthomosaics and detailed 3D models of the area and with the help of this, we create high-accuracy cadastral maps of even complex or difficult-to-access environments. With the help of drones, we do an aerial inspection of areas that are usually not accessible or dangerous for a person to have a look at.  Places like a chimney, cell towers, forest fires, etc. with drones inspectors can collect visual data without exposing themselves to potential harm.
