Abstract:
Taking the basic data from Chaoying mansion in Xi′an city as on example method that apply professional software Ar- cView of GIS, to establish subsidence graph and three-dimensional simulated subsidence chart of is studied through synthetic pro- cessing and analysis. It is pointed that DEM can realize expression of above expectant production and create target figure finally. The results indicated that subsidence graph and three-dimensional simulated subsidence chart by ArcView could represent more quickly, briefly, accurately and more intuitively, vividly, truly than traditional means. For decision-makers or builders, they can achieve subsidence and distortion information effectively in order to improve efficiency and precision. Thereby it can provide sus- taining technique and decision-making basis. It is an effective measure to express subsidence observation results.
