研究概要:Since 1991, the National Land Agency of Japan has been updating the digital land use data of Japan using Landsat TM and SPOT satellite images. It is well known that point wise classification method such as maxmum likelihood classification are not so efficient in updating conventional land use data with satellite data. In this project, instead of using the point wise classification method, the image interpretation method is used for updating the data. This paper describes how the vegetation index derived from satellite data is used for effectively updating the land use data in Japan.
