| Abstract: | In this paper,regarding remote sensing images as the update datas,using object-oriented classification method,on the object level,conduction and analysis are carried out.Regarding updated and finished elemetns as the prior knowledge,geographical elements are hierarchically updated.The use of unchanged information duing the update period of topographic map and main geographical elements and updating methods are studied.As showed by the results,this method has the characterisitics of fast and practical in automatically updating information and has a broad application space. |
