Abstract: The crowd degree of buildings is a very important aspect for the assessment of environmental quality of urban communities. Remote sensing imagery with high spatial resolution provides more detailed spatial information about land covers and makes it possible to assess the quality of communities in detailed scale. Four factors were proposed to assess the crowd degree of buildings based on the combination of high spatial resolution imagery and some fundamental principles including estate and geostatistics methods. Five typical communities in Xiamen City were selected to demonstrate the application of those indices. Results suggested that these indices could describe the building crowd degree from different aspects, and it provided a new approach in assessing environmental quality of community through high spatial resolution remote sensed data.

Key words: high-resolution remote-sensing image, building crowd degree, community
