基于HJ-1-A卫星CCD相机遥感影像的水体提取

Water Body Extraction Using HJ-1-A Satellite CCD Images

摘要: 采用面向对象的分析方法(object based image analysis,OBIA),结合水体特征对国产环境卫星(HJ-1-A)CCD相机影像的水体信息进行快速分析、处理和提取.结果表明,对于中低分辨率多光谱遥感影像水体信息的提取,该方法的提取精度在95%以上,优于最小距离法(minimum distance).

Abstract: The water body information of the image data from the domestic environmental satellite(HJ-1-A) CCD was analyzed,processed and extracted quickly with the method of OBIA(object based image analysis,OBIA)and the water body characteristics.The results showed that the method of OBIA can achieve an accuracy of 95% for the extraction of water body’s information to low or medium resolution multispectral remote sensing images,and was superior to the method of minimum distance
