Abstract

Beijing is the center of politics, economy and culture in China. In recent years, the rapid development has been taking place in the city, especially, after the successful application for 2008 Olympic Games. In order to know and control the city development it is necessary to monitor the changes. Timely and accurate change detection of the city is important for the administrant departments to promote better decision making. Given the current techniques available, remote sensing provides the most feasible approach to regional and larger scale land surface change detection. A critical step of many change detection methods is to select an appropriate threshold value to extract change information. In the paper, an adaptive determination method based on polygon area fit rate is brought forward. A method based on the integration of remote sensing and GIS is presented to analyze the change types. We apply this method in the change detection practical project of Beijing city and get good result.
