RESEARCH ON VALIDITY MEASUREMENT OF MEGACITIES RENEWAL POLICIES AND SUITABILITY SCALE FOR URBAN REMOTE SENSING DATA APPLICATIONS: TAKING BEIJING’S DUAL CONTROL POLICY AS AN EXAMPLE

Abstract. Urban renewal has become the application hotspot of urban remote sensing development in recent years. However, scientific distribution weight relationship between indicators reflecting progress and effectiveness different goals tasks, comprehensive evaluation policies existing indicator system require further in-depth research. In particular, there is no clear standard for caliber data cities spatial indicators. Taking Beijing’s dual control policy as an example, this paper measures mega-city represented by Beijing based on analytic hierarchy process, analyzes types suitable renewal. addition, suitability scale given through case studies. By analyzing actual validity dual-control implementation, it concluded that image big > artificial intelligence algorithm historical data. It necessary to focus automatic identification exploration changes sensing, design calculation physical examination future. Furthermore, work needs be carried out improve evaluability, accuracy objectivity practical renewal, explore establishment a guidelines.
