The generation of photogrammetric data with unmanned aerial vehicle

With the development of modern technology, unmanned aerial vehicles have begun to be used in different areas around the world. The use of UAV as an important platform especially in photogrammetric studies has been rapidly spreading in our country considering the advantages of speed, time and cost. The studies made with UAV presented as an alternative to traditional methods; high temporal and spatial resolution of data production and at the same time with lower cost data production is achieved. The aim of this study is producing photogrammetric data production with the modern UAV technology of today. For this purpose, two different study areas which were overall size 60 hectares at Sogullu neighborhood in Sile district in Istanbul province, and overall size 78.3 hectares at Organized Industrial Site in Baspınar neighborhood in Sehitkamil district in Gaziantep province. In these two study areas, the aerial photographs obtained by the UAV were processed to produce three-dimensional models, orthophoto and digital surface models. Different methods have been analyzed in the production phase of photogrammetric data. In addition, cost analysis was performed by comparing different items such as hardware, software and costs analysis of UAV technology and traditional methods.
