| Abstract: | Provides a disquisition on geometric characteristic for error model of 2D random linear segment in vector GIS,discusses ascertaining theory and methology based on continuous viewpoint and the equivalent probability density error model(marked as Tepdem) as well,and which establishes a theoretical basis for both error distribution characteristic of spatial linear entity in vector GIS and ascertainment method for point position with highest coordinates accuracy.Test validates the correctness on theoretical deduction as well as obtains some important conclusions by case study and visualization analysis. |
