Higher resolution images acquired by remote sensing satellites provide the possibility of remote sensing estimation for urban environmental quality in the scale of flat. The technology is studied in the paper. Based on the selection of the environmental estimation index, such as vegetation sight framework parameter and building capability, the index such as the average view area, the alternation complication degree of objects in image and force by outside objects including mountain, water, vegetation, road, etc. and related analysis method are studied. Finally, the blur judge method is utilized to get the distinguished matrix of each parameter index, then the final result is obtained for overall index estimation of each flat. In this paper, the QuickBird remote sensing imagery of Xiamen city is used to experiment the related estimation method. The environmental estimation experiment by 8 representative flats shows the method, which use satellite higher resolution imagery to estimate environmental quality for flat is cost-effective and easy to use.
