将传统分类方法和加入地理控制界线分类方法进行比较,后者分类精度为94.73%,比传统分类方法提高了近3个百分点。这种方法对于解决卫星遥感中的同谱异类问题,提高分类精度,有较重要的意义和作用。本文以乌鲁木齐市为例,主要研究了同谱异类问题。 Comparing the traditional classification method with the geographical classification method, the accuracy of the latter classification is 94.73%, which is nearly 3% higher than the traditional classification method. This method has the more important meaning and effect for solving the same-spectrum heterogeneity problem in satellite remote sensing and improving the classification accuracy. This article takes Urumqi as an example, mainly studied the same type of heterogeneity problem.
