Gao Xi-fen · Shanxi Architecture · 2008
According to the features of line works,the paper discusses the application of quasi-geoid refinement in hill and low-mountain area.Using the example,it proves that if fitting selection point interval is less than 5 km,the fitting result can meet centimeter scale,in order to promote the application of such method.
