Land Cover Change Detection using ALOS and LANDSAT Data in Thailand

Land cover change detection is necessary for updating land cover maps. The two multi-date images from remotely-sensed data of ALOS AVNIR-2 and LANDSAT-5 TM were used to detect land cover. These images covered in part of Phitsanulok Province, Lower Northern Thailand, which is one of the fertility areas for rice production. These data have been used to classify land cover with supervised classification by maximum likelihood, and being adopted by using the training samples obtained from the ground truth. The results showed the preliminary changes of land cover over a 3-year period, and displayed the difference of land cover map in the study area. These maps are utilized for stratification approach and land use planning in Thailand
