| Abstract | This study aims to compile the terrestrial boundary data of Thailand into a vector geographic information system using Universal Transverse Mercator (UTM) coordinates, Zone 47 North, with the primary datum as World Geodetic System 1984 (WGS 1984) from Sentinel-2 satellite imagery. The objective is to compare the boundary data derived from this study with those previously compiled by various government agencies. The study found that the calculated area of Thailand's terrestrial boundary from this research is 321,204,866.73 acres (513,927.79 square kilometers). When comparing this boundary data with previously compiled data from other state agencies, it was observed that the Royal Thai Survey Department's boundary data shows the smallest difference, at 0.42%, equivalent to 1,370,404.46 acres (2,192.65 square kilometers). Comparatively, the Department of Lands's boundary data exhibits a slightly higher difference at 0.71%, equivalent to 2,304,335.74 acres (3,686.94 square kilometers). Finally, the largest difference was found with the boundary data from the Department of Provincial Administration, at 0.72%, equivalent to 2,323,832.92 acres (3,718.13 square kilometers). |
