UAVs and Photogrammetry

Abstract

The Unmanned Aerial Vehicle (UAV) is a remote-controlled aircraft. It can be operated remotely in real-time or pre-programmed to fly autonomously on the pre-defined routes. Popularly known as a drone, the use of this type of aircraft is increasing in all sectors. Within the last few years, UAVs have opened a new realm of opportunities for Surveying and Mapping, introduced better, faster, and cost-effective methods for the practice of Photogrammetry. In this paper, we discuss the evolution of Photogrammetry, the evolution of UAV, UAV in Geomatics, the impact of UAV in Photogrammetry, the current trend, and future implications.
