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 homogeneous 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.
