Change detection and analysis of housebreaking in 2008 Beijing Olympic main venue using airborne remote sensing photos

Beijing will hold the 2008 Olympic Games. The main venue locates in northern Beijing, where there were villages, residential houses and commercial buildings. In order to help Beijing Olympic committee on the planning of housebreak and monitoring the construction implementation, the Institute of Remote Sensing Applications (IRSA, CAS), used the airplane to obtain true color photos from 2001 to 2003 in order to monitor the progress of the housebreaking. This work introduced the change detection methods and the land use changes were statistically analyzed, which show clearly the distribution of the housebreaking area, as well as the amount of houses or buildings. Until now 718 mu of houses or buildings remain to be broken down in near future.
