Determination of Land Use Change Categories Using Classification of Multitemporal Satellite Image Data

초록

This study attempts to determine major land cover change categories using satellite remote sensing data collected at three different times. The study area covers approximately 10,000 km2 of the provinces of Pyungan and Hwanghea in western region of North Korea. Using multitemporal Landsat imagery obtained from 1973 to 1993, land cover types for each year were classified. Primary land cover change categories, such as the conversion of forest land into cropland, were defined based on the classification accuracy of each data set and the temporal pattern of land cover classes observed on three classified maps.
