本文对长江三峡地区资源遥感图像处理中的三个技术难题进行了讨论并提出了解决办法：（１）跨两高斯投影带的卫星遥感图像的几何校正，采用分两个子区校正的办法，提出一个简便而有效的确定子区范围的方法；（２）同类异谱问题采用类型细分的方法来解决，类型细分时考虑阴阳坡、作物季相及植被覆盖度等影响因素；（３）同谱异类带来的错分类，可引进地理控制系统对其校正，从而提高了成图精度。
In this paper, the three technical problems in resource remote sensing image processing in the Three Gorges area of the Yangtze River are discussed and some solutions are proposed. (1) The geometric correction of satellite remote sensing images across two Gaussian projection bands is proposed by the method of two sub- A simple and effective way to determine the range of sub-areas; (2) the same-type spectrum problem is solved by type subdivision; the factors such as the slope of yin-yang slope, crop season and vegetation coverage are considered in the type subdivision; (3) The same classification brings the wrong classification, can be introduced into the geographical control system to correct it, thereby improving the accuracy of mapping.
