Monitoring Land Use/Land Cover Change in Tha Chin River Basin

Land use/ land cover (LULC) changes influence the whole natural system directly or indirectly, so monitoring these changes is essential to balance the natural environment. This research surveyed changes in LULC in the Tha Chin River Basin. Using Google Earth Engine and ArcGIS, Landsat 5 and Landsat 8 Thematic Mapping satellite photos were utilized to identify LULC classes for the years 2000, 2010 and 2020 for the Tha Chin river basin. Fifty training samples for five classes were collected by supervised classification to analyze land cover types in the Tha Chin basin. Among these five classes, the urban area shows a significant change from 2000 to 2020; the second significant change is the forest area. The monitoring of changes in LULC would provide a crucial basis for the region environmental management and integrity in the Tha Chin River Basin.
