| Abstract: | Combining with the working practice,this paper introduced a kind of new three point drawing arc algorithm,specific elaborated the algorithm ideas,using positive and negative algorithm of coordinate,according to a certain angle calculation of circular coordinates,and then use the function of mapping linear,using the linear approximation method to realize.And pointed out that development circular system could directly improve the working efficiency of digital mapping in WinCE GPS hand book. |
