การหาความสัมพันธ์ระหว่างอุณหภูมิพื้นผิวกับดัชนี NDVI NDWI และ NDBI ในเขตเทศบาลนครนครราชสีมา

Abstract

The purpose of this research was to study land surface temperature and the relationship between NDVI, NDWI, and NDBI in 2009 and 2021 in 2 time periods from Landsat 5 and 8 satellite images using Google Earth Engine open source software to analyze the data. It was found that the land use change between 2009 to 2021 has changed land use from agriculture to Urban and built-up area and the land surface temperature study is summer season found that, the maximum surface temperature increased from 29.71 °C in 2009 to 34.78 °C in 2021, and in winter, the maximum surface temperature increased from 30.12 °C in 2009.  to 31.82 °C in 2021. Furthermore, studies show the relationship between LST and NDVI, NDWI were negatively correlated. And inversely variable The surface temperature and the NDBI index were inversely positively correlated. The results of this study can be used to plan appropriate land use and cope with climate change.
