Özet
Kocaba & scedil;lar geothermal field is located in & Ccedil;anakkale province in northwestern T & uuml;rkiye. A well was drilled to a depth of 650 m with a temperature of 46 degrees C. There is also a geothermal spring with a temperature of 38.1 degrees C. The objective of this study was to model the Kocaba & scedil;lar geothermal field for the first time using an unmanned aerial vehicle (UAV) equipped with a dual camera to capture high-resolution thermal infrared (TIR) and visible (RGB) images. The UAV survey was conducted on January 6, 2023, when the air temperature was low and the meteorological conditions were favorable for image acquisition. The flight altitude was 40 m above ground level, and the flight speed was 2.5 m/s. Image front and side overlaps were 80% and 70%, respectively. As a result of processing a total of 1718 TIR and RGB images, a high-resolution TIR orthophoto (5.25 cm/pixel), an RGB orthophoto (1.37 cm/pixel), and a digital surface model (5.47 cm/pixel) were generated. The generated images were visualized in Geographic Information Systems software. The surface temperature in the geothermal field varied between 6 degrees C and 38 degrees C. The Kocaba & scedil;lar geothermal field will be monitored for an extended period using UAV technology in order to contribute to the development and sustainability of the utilization areas for geothermal energy.
