THE DEVELOPMENT OF CAPTURING LAND USE INFORMATION FROM RMOTE SENSING IMAGE IN CHINA

From nineteen seventies, utilizing RS information to capture the land use information began in China and the technology of capturing land use information from RS image developed rapidly.Authors divided the developing stage of the technology of our country into three different periods. First period, every stage of the work procedure is tiring and all the work was artificial. Second stage, the calculating of areas of every land use categories achieved automatic. Third stage, we utilized the full digital image to interpret and capture the land use information in the environment of the integration of RS and GIS. The process of digitizing was abbreviated. The precision was enhanced of course. And authors think that the technology in the near future is to develop the automatic system of image interpretation.
