THE STUDY OF CORRELATION BETWEEN LAND SURFACE TEMPERATURE WITH LAND USE, A CASE STUDY OF RAYONG PROVINCE

Abstract

The objectives of this research were studied correlation between surface temperature and land use. Rayong province using satellite data LANDSAT-8 and calculate the land surface temperature. There were four factors such as 1) Conversion TOA Radiance 2) Conversion to Top of Atmosphere Brightness Temperature 3) Vegetation Index 4) Proportion of soil cover vegetation. The study of land use through the supervisory classification method. The results showed that the most of land for agricultural is in Klang district, which was 1,702.04 Sq.Km. (46.66%), The most of land for forest is in Khao Chamao district, were 948.32 Sq.Km. (26%), The most of land for urban and building is in Muang district, were 485.14 Sq.Km. (13.30%), The most of land for others is in Muang district, were 449.12 Sq.Km. (12.31%), The most of land for others is in Muang district, were 449.12 Sq.Km. (12.31%), The most of land for water is in Pluak Daeng district, were 62.96 Sq.Km. (1.73%). The overall accuracy assessment of land use was 82 percent, Average land surface temperature of each district, It was found that Pluak Daeng district had the highest average temperature of 29.10 degrees Celsius. Followed by the Muang district has an average temperature of 29.08 degrees Celsius. And Nikhom Phatthana district had an average temperature of 28.82 degrees Celsius. The correlation between average surface temperature and land use (Urban and Building, Others, Water,Forest and Agricultural Land). The data was analyzed using Pearson's correlation coefficient statistics. The research results were found that The correlation coefficients (r) were 0.742 0.468 - 0.324 -0.642 and -0.663, respectively, at a significance level 0.05.
