Unmanned Aerial Photogrammetic Survey is the use of Unmanned Aerial Vehicles (UAVs) to take photos for use in photogrammetry, the science of making measurements from photographs. Instruments manufactured for UAVs could be mounted on unmanned flying platforms of various sizes and types, such as octocopters. These machines are suitable for the full geodetic survey of a study site by creating a point cloud of measurements of nearly homogenous quality and accuracy. These detailed point clouds (of various types of data) could be used in line with orthophotos etc. to obtain a complex data system representing the study site. Similarly to manned aerial surveys, UAVs are suitable to acquire three-dimensional digital models and orthophoto mosaics for a certain area. The biggest downside of this technology is that these UAVs, especially the smaller ones, could survey only a smaller area.〔Légi fényképezés a gazdálkodásban és a közszolgáltatásban Arial Photogrammetry in Economy and Public Services - E-Government Tanulmányok XL. - tankönyv 1-126 p. 2014, - Írta és fényképezte: Bakó Gábor, Lektorálták: Licskó Béla és Tózsa István.
