New approach for agricultural research and monitoring of land slide: using of UAV system.

In this study, agricultural area planning and landslide monitoring have been performed. For this purposes, two different research areas have been selected. One of them is Gaziosmanpasa University, Farming Faculty agricultural research area, the other one is Tokat Industrial Area Landslide district. All research areas have been monitored by using SONY_A6000 camera that is mounted on GEO_2 UAV multirotor, manufactured by TEKNOMER. The flight plan performed with 100 m altitude and with 80% flight columns frontal overlap and 60% side overlapped. GCPs have been observed with Topcon and Trimble GNSS geodetic receivers and processed with LGO V.8.4 software. For the agricultural area a total 985 photos have been taken for 344 ha area. For the landslide area a total 291 photos have been taken for 50 ha area. The photos have been evaluated by PIX4D software. For the agricultural area, 25 GCPs have been included in the evaluation; images have been produced by pixel matching algorithms. As a result of the evaluation RMS has been obtained as +/- 0.054 m. For the landslide area, 8 GCPs have been included in the evaluation; images have been produced by pixel matching algorithms. As a result of the evaluation RMS has been obtained as +/- 0.018 m.
