| 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. |
