Designing and practical application of Unmanned Aerial Vehicles (UAVs) in geomatics is a new interdisciplinary field of science and research, which arose in last years. UAVs enable execution of small areas low altitude photo shoots as well as fast obtaining of multitemporary high resolution image data in various spectral range. Potentially UAV-borne Laser Scanning is also possible. New techniques of data acquisition and wide range of possible applications of UAVs in obtaining geoinformation are the subject of research of ISPRS Intercommission Working Group I/V Unmanned Vehicle Systems (UVS) for Mapping and Monitoring Applications. The paper synthetically reviews recent developments in the field of Unmanned Vehicle Systems and outlines further directions of research. It presents construction of typical UAVs and analysis of sensors installed on their platforms. Moreover it describes photogrammetric and remote sensing technologies and various kinds of applications in geomatics which base on optical multisensoral and LiDAR data and technical aspects of UAVs application.
