[Abstract]

　The objective of the study is to develop remote sensing methodologies for monitoring landcover/use distribution and its temporal change with satellite images. Landsat TM and MSS images with 30-80m spatial resolution from 1970's-90's and NOAA AVHRR images with 1km resolution from 1980's-90's over South-East and East Asia were collected to assess the landcover changes of the area over twenty years. First, an automatic image mosaicing method was developed to composite a large amount of satellite images(TM,MSS) covering the area. Also, an integrated landcover classification and assessment method was developed which utilizes both of TM, MSS and AVHRR data together to take advantages both of high spatial resolution characteristics in TM and MSS and frequent observation characteristics in AVHRR. Further, landcover classification map over East Asia was obtained from the time series monthly AVHRR NDVI images from 1983 to 1990 with 8km spatial resolution based on classification of the temporal pattern of the NDVI values.
