摘要: 主要针对遥感影像屏幕数字化效率较低问题,提出了显着地物矢量跟踪方法:包括显着地物的分析、遥感影像数据的预处理、显着地物信息的人机交互提取、显着地物的矢量跟踪等步骤,并利用辽宁省东部新宾县TM遥感影像对此方法进行了应用与验证。

Abstract: Rapid development of computer technology brings about emergency of interactive interpretation of remote sensing images on computer screen. It holds higher precision and can directly enter geographical information system. More attention should be paid to its low efficiency. This paper shows the method of vector trace of distinct objects in screen digitalization of remote sensing images. With equal and higher precision, the method can greatly enhance the work efficiency, and possesses the important significance to the design and development of special software for manual screen digitalization of remote sensing images.
