Aerial surveying and geo-mapping is now done with an UAV (Unmanned Aerial Vehicle). Aerial surveys can provide information on many things not visible from the ground and data captured via drone mapping perfectly complements what engineers can see from the ground.
Autonomous drones have become the leading technology for creating topographic surveys. In construction, drones can be used to survey building sites to help monitor and report progress, spot errors early on and avoid rework.
Because UAVs are relatively inexpensive, it is feasible for companies to have their own fleet, and that allows for rapid surveys over large land areas to be completed quickly. With GPS equipped drones, digital cameras and powerful computers, surveys with an accuracy down to 1 to 2 cm is very possible.
Drones can provide Geo-Referenced High Altitude Aerial Photography and Videography Site Inspections with Full 3D Terrain Mapping.
