ASSESSMENT OF DROUGHT IMPACTS IN DIFFERENT LAND COVERS USING A REMOTE SENSING INDEX: A CASE STUDY IN ANDONG, S. KOREA

摘要

Drought monitoring using the remote sensing instruments is efficient for assessing the drought impact in the different land covers. This research employed the normalized different moisture index (NDMI) generated using the Landsat image acquired in Andong, South Korea in the drought period for assessing the drought impact in the different land covers. The statistical results show that, in the Landsat image acquired in the drought period, the NDMI value measured in the vegetation area is higher than the NDMI values measured in the other land covers.
