Abstract
This research aims to monitor land-use change in 2 periods, i.e., 2019 and 2023, by using Remote Sensing Technology and band indices. Research methodology consisted of: 1) classifying land-use based on data obtained from Sentinel-2 satellite into 4 types including: agriculture, forest, urban, and water; 2) analyzing Normalized Difference Vegetation Index (NDVI), Normalized Difference Built - up Index (NDBI), and Normalized Difference Water Index (NDWI) as well as analyzing relationship between land-use and NDVI, NDBI, and NDWI; and 3) comparing land-use change of 2019 and 2023. The results revealed that land-use change in Mueang Maha Sarakham District, Maha Sarakham Province, in 2 periods of time was as follows: reduced areas were agriculture and forest, and increased areas were urban and water.
