Abstract: Perfect monitoring and evaluating system of urban environment is very important. Traditional monitor and evaluation system should be revised with the support of high resolution remote sensing technology. High resolution remote sensing satellites and their data, especially IKNOS satellite of Space Imaging Company, are introduced. Then the application feasibility research is done based on it. In addition, the environmental evaluation application model based on the high resolution remote sensing satellite data is given. This model has four main characters, and contents of this model are further explained in three parts. The first part is the urban environmental evaluation system. With the support of high resolution remote sensing satellite data and other environmental information, environmental evaluation system can be constructed, which is not only the basis of urban environmental evaluation, but also the basis of application of high resolution remote sensing data. The second part is Metadata management. Constructing the Metadata management system and adding environmental Metadata database to the origin database system are needed, and Metadata management benefits the data share and data efficiency acquiring. The third part is environmental evaluation factor getting and analyzing. Getting the evaluation factors from high resolution image should use the method of texture instead of the traditional method based on multiple spectrum. Based on these factors, special environmental models and GIS should be combined to do the urban environmental evaluation work. In the end, typical initial research is done in Xiammen Environmental Bureau.
