| Abstract: | 〗This paper proposes an algorithm based on triangulation and directional line mosaic to construct a high precise coordinate transformation grid model, integrating graphics structure, data type and the requirement of grid mode precision, combining the graphics idea. Taking eastern and southern Chinese cities for comparison, the experiments show that the method takes the graphics structure effect on selected the known points, that the error propagation is effectively controlled, that good effects of grid model are achieved, that there is no influence among the sub triangle region, and that there is no mosaic gap. We test and verify the feasibility and reliability of this method. |
