摘要
针对利用Landsat TM遥感影像中水体信息识别的常用方法对细小水体识别的局限性作了深入研究,提出了新的基于ERDAS IMAGING的较小水体识别方法。将TM影像中某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识别。该方法有效地提高了细小水体识别的精度。
The limitation of small water-body recognition by the common water-body information recognition method in Landsat TM remote sensing image is analyzed, and a new small water-body information recognition method based on ERDAS IMAGING is presented. The false color synthetic map composed by 3 wave bands is converted to IHS colorful space, and a model is constructed for small water-body recognition. The method raises the accuracy of small water-body recognition.
