Abstract: This paper proposes a fusion approach to detect the urban boundary. Two boundaries were obtained using the DMSP-OLS night light data and Landsat image data, respectively. A proper weight was chosen to fuse these two boundaries obtained from different data sets so that reliability of the final results was improved. Experimental results have shown validity of the proposed approach.

Key words: DMSP-OLS night light data, Landsat satellite image, urban boundary
