Abstract

This study investigates the relation between surface temperature and land use type. The study site is located in Banchiao, a built-up area in New Taipei City, Taiwan. The area is about 3.5 square kilometer. Thermal images were taken with an ITRES TABI-1800 on September 14, 2014. Image spatial resolution is 0.5m. Land use type information is obtained from the NLSC Land Use Map (2017). The relation is then analyzed. Besides, several spectral indices, NDVI, NDBI, NDWI, are derived from a Sentinel-2 satellite image scene. The 1*1m DSM can show the surface elevation was scanned by Leica ALS60 Airborne Laser Scanner. Regression analysis and correlation coefficient are mainly method to distinguish the correlation between surface temperature and land cover. Expected that the elevation of building and temperature are a low correlation, but the shadow from high building cause the low-temperature area. The temperature in the the industrial area is higher, the potential causes include material or energy discharge. Through research, the meticulous correlation between surface temperature and land cover will be found.
