Land surface temperature inversion for Fengyong Expressway based on Landsat 8
During tunnel construction,high ground temperature heat damage not only affects the efficiency of mechanical equipment and construction progress,but also worsens the operating environment and poses a threat to personnel safety.There-fore,accurate identification of geothermal anomaly areas is very important for tunnel construction.Thermal infrared remote sensing is the use of remote sensing methods to detect the temperature of the Earth's surface,and using remote sensing technol-ogy to retrieve surface temperature is becoming increasingly reliable.Taking the Fengqing Linggangdi Tunnel of Fengyong Ex-pressway in Yunnan Province as the research area,using Landsat 8 image data and atmospheric correction method to retrieve the surface temperature in the research area,then using DEM data to create topographic slope orientation files,extracting the surface temperature according to the distribution of sunny and shady slopes,and analyzing the surface temperature anomalies in combination with geological structures to delineate geothermal anomaly areas.
