THE EFFECT OF DIFFERENT FLIGHT HEIGHTS ON GENERATED DIGITAL PRODUCTS: DSM AND ORTHOPHOTO
Unmanned Aerial Vehicle (UAV) allows you to create digital surface models (DSM) and orthophotos of an area in a short time by photogrammetric methods. In the last decade, UAV and Global Positioning System (GPS) have been used to create real, reliable and high-resolution maps. In this study, the effect of flight height on DSM and orthophoto was investigated. Two flight plans at a height of 30 to 50 meters were prepared. Images taken with UAV were used to produce DSM and orthophoto. Resolution of maps were compared when models were produced. Compared to a flight height of 50 meters, a more detailed and high-resolution model was created with 30 meters. Although the flight data from 30 meters gave better results, the flight process took longer. Also, more photos were taken and the file size took up more space. As a result of this comparison, it was determined that the flight height should be determined according to the terrain structure, accuracy, precision and time-cost balance expected from the job.
