| 摘 要： | 针对利用Landsat TM遥感影像中水体信息提取的常用方法对细小水体提取的局限性作了深入研究．提出了新的水体提取方法。首先利用TM2＋TM3〉TM4＋TM5的谱间关系提取水库、坑塘、宽的河流，然后将由3个波段组成的假彩色合成图转换到IHS彩色空间，构建模型进行细小水体的提取，最后将用2种方法提取的结果进行合开，可以完整地将水体提取出来。该方法有效的提高了细小水体提取的精度。

| Abstract: | Owing to the limitations of the commonly used water-body information picking up methods in picking-up small water bodies, this paper introduces a new water body information picking-up method. First, the formula TM 2 + TM 3 + TM 4 + TM 5 was used to pick up reservoirs, ponds and broad rivers. Then the false color synthesized map composed of the 3 band waves was converted into HIS colorful space to construct a model to pick up small water-bodies. Finally, the results of the two methods were integrated and thus the water-bodies can be picked up completely. This method improves the accuracy of small water-body picking-up. |
