2000坐标系转换模型的试验分析与研究
Experimental analysis on transformation model of 2000 coordinate system
摘要
Abstract
In terms of the problem of coordinate conversion in a larger area, this study had investigated the four parameters model in a 2000 coordinate system transformation. Three test plans were used to compare the transformations. In particular, the transformation from 1980 Xi’an coordinate system to 2000 coordinate system was described in a great detail including process and requirements. In addition, the accuracies of experimental data were analyzed and the parameters of coincidence points were calibrated in different schemes. The results show that the four parameters model transformation is feasible, and the coordinate conversion accuracy of control points can meet the requirements of control point conversion accuracy. The study provides some useful reference values for the construction of earth coordinate system.关键词
