Application of airborne thermal infrared remote sensing in geothermal exploration of Zigui county

Abstract

Abstract: Traditional geothermal exploration methods feature long-term cycles and high costs.In Zigui county,located in the mountainous area of western Hubei province,complex topography further inflates exploration expenses.This study applies airborne thermal infrared remote sensing (TIRS)technology to overcome these challenges.A 1.05 km² rectangular area centered on Wulong hot spring in Zigui county is selected.A DJI Mavic 3 unmanned aerial vehicle(UAV)equipped with a thermal infrared camera conducted winter daytime and nighttime aerial surveys,identifying five geothermal anomaly zones.After interpretation and screening,two geothermal target areas are determined.Field investigations show that one area matched the Wulong hot spring outcrop,while the other is a newly discovered geothermal site.The results prove that TIRS technology is reliable and applicable in geothermal exploration,effectively shortening the exploration cycle and reducing costs.

Key words: TIRS, infrared remote sensing, UAV, thermal anomaly, mountainous area of western Hubei
