【Abstract】 Beijing will hold the 2008 Olympic Games. The main venue locates in northern Beijing, where there are villages, residential houses and commercial buildings. In order to help Beijing Olympic committee on the planning of housebreak and monitoring the construction implementation, supported by the project of Science and Technology Olympic Game and the Knowledge Innovation Project of Institute of Institute of Remote Sensing Applications (IRSA, CAS), IRSA used the airplane to obtain true color photos in July 2001, 2002 and 2003 respectively in order to monitor the progress of the housebreaking in the area. This paper introduced the change detection methods and the land use changes from 2001 to 2003 were statistically analyzed by the interpretation of the mosaiced photos, which show clearly the location of the housebreaking area, as well as the amount of houses or buildings. Until now 718 mu of houses or buildings remains to be broken down in near future. According to our plan for every June or July from 2004 to 2008, we will take airplane photos to detect construction progress and present the photos to the public.更多还原
