| Abstract: | Urbanization has profoundly changed people＇ s living environment and life style. It is urgently required to solve the problem that how to reasonably and timely get the information about changes of urban construction land. This parer summarizes methods those using remote sensing images to monitor urban geography changes, and compares the algorithms＇ efficiency and accuracy of some important aspects in the methods. Then this paper proposes a better set of urban geographic information change detection program. |
