Renewing urban large-scale topographic maps by using Quick Bird panchromatic remote sensing images
YANG Ze-yun1, KANG Jia-yin2, ZHAO Guang-dong3 (1. Heilongjiang Institute of Technology, Harbin 150050, China; 2. Liaoning Technical University, Fuxin 123000, China; 3. Liaoyang Surveying and Designing Institute of Land and Natural Resonces, Liaoyang 111000, China)
Urban large-scale topographic maps can be fast renewed by means of overlapping the original digital line graph (DLG) and up-to-date remote sensing images of high resolution which has been geometrically rectified in orthography with the precise polynomial transformation. Quick Bird panchromatic remote sensing image is used, which is suitable for renewing 1:2000 scale topographic maps in an urban area with even terrain.
