| Abstract: | The technology of varying map scale information extraction in this paper is base on GIS spatial processing technology, spatial analysis model, spatial querying method, and AHP hierarchy mathematical method. It studied the model and ultimately simulated and realized the information extraction procedure in IDE entironment. Using Beijing city roads as basic research data, it established information extraction model based on ArcEngine 9.0 component technology in DOTNET language environment. It changed the parameters of the model again and again during the experiment in order to retain the overall outline of Beijing city road and finally establish the varying map scale information extraction model for city roads. |
