Paper Abstract

With lower speed of geographical data upgrades than the corresponding demands for them, geographical data update becomes the bottleneck that geographical Information Systems (GIS) face at present. Remote sensing images are the most available data source of geographical data upgrade. In this paper, a strategy of selecting the maximum variance between clusters to detect the changed area is put forward. Based on the changed area, the geographical data can be updated using remote sensing images. The validity of the strategy is proved at the last of the paper.
