| Abstract: | The investigation of land cover in Yinda irrigated region was selected as cast site. According to the characteristics of land types and the requirement of spatial resolution of the investigation, panchromatic spot image and multi-spectral TM image were used to generate new false color composite image with 10m spatial resolution by using Brovey image fusion. The precision of image was analyzed and tested. The results show that the fusion image could meet the demand of application. |
