A method for detecting land cover change using vegetation index calculated from Landsat TM data is proposed in this paper. The northern and middle region of Mie prefecture is adopted as study area. Five Landsat TM scenes, which were observed in same season, were selected. The five scenes were geo-corrected. NDVI (Normalized Difference Vegetation Index) were calculated, and merged into one image dataset. Color combination of selected three different NDVI were investigated from the viewpoint of land cover change. Clustering result of the merged image dataset were also investigated.
