Abstract: This research was aimed to integrate approximation of Land Surface Temperature using value of derivative analysis retrieved from Terra Modis data of MOD11A2 product during 4 time periods years of 2004, 2008, 2013, and 2018, selecting Sakon Nakhon Province was chosen as study area. Terra Modis data Product MOD11A2 was used, which was in monthly format of the year 2004, 2008, 2013, and 2018, 48 data in total for the image processing approximate of Land Surface Temperature. The results showed that Land Surface Temperature data analyzed from the satellite data was similar to the Land Surface Temperature data obtained from Thai Meteorological Department. The correlation was performed using correlation method, it was discovered that the correlation coefficient R = 0.988 was very high. In addition, using the above data to analyze by the simple linear regression analysis, it was found that the coefficient of determination, R2 = 0.9774, meaning that the use of satellite data for this surface temperature analysis was reliable and the methodology in this study could be used to analyze surface temperatures in other areas of Thailand.
