摘要
选择高分遥感影像的时相是利用高分遥感影像精确定位湖泊河流湿地自然边界的关键问题之一。在没有或缺少水文观测数据的情况下,依据河流湖泊湿地的定义,本文提出了一种用于河流湖泊湿地边界定位的高分遥感影像时相快速选择方法,试验结果表明该方法合理、准确、有效。
To locate the natural boundaries of lake and river wetlands with high resolution remote sensing images accurately,it is one of the key issues to select the appropriate phase of high resolution remote sensing images. In the absence or lack of hydrological observation data,a phase selection method of high resolution remote sensing images for river and lake wetland boundary location is proposed according to the definition of river and lake wetland,test results show that this method is reasonable and effective.
