摘要
近年来,SPOT 5影像被广泛应用于土地利用类型的调查中[1],一方面,为我们进行土地利用类型分类更新提供了新的信息源;另一方面,对遥感的室内解译提供了更高更新的要求。本文以常德市汉寿县为例探讨在进行土地利用类型分类更新中前期图像处理、解译标志的建立以及人工目视判读中的难点和重点,对于在遥感图上不易判读或容易判错的地物特征给予总结,一定程度上提高了遥感目视解译的准确性。
In recent years, SPOT 5 image is widely used to survey the types of land - use. On the one hand, it provides a new source of information to update the types of land use, while it also provides higher requirements for the indoor interpretation of remote sensing. This paper has Hanshou County, Changde City, as an example to discuss the image pre - processing, interpretation signs, as well as the difficulties and priorities of artificial visual interpretation in the updating of land - use types, to sum up the characteristics of surface features which are difficult to interpret or easy to interpret wrong. To some extent, it improved the accuracy of remote sensing visual interpretation.
