3D models using UAV

Last decade saw a considerable growth in number of methods to create 3D models for buildings. Some companies have developed their own online maps systems. One of the most well-known of them is Google Maps. The maps are infrequently updated because the process is costly and labor-consuming, and, as a rule, the update is not necessary. The process of 3D model creation for a separate building using such equipment as LIDAR and UltraCamD is very expensive; and land-based aerophotogrammetry has its limitations based on the height of the building and its location that should be suitable to place the camera to get an accurate photos.
