摘要
结合作用所参加的研究工作 ,探讨了我国近年来利用遥感数据获取土地利用现状信息的技术方法的阶段性发展规律 ,并对其发展趋势做出了预测。
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.
