一种变比例尺地图的导航算法

Variable Scale Map Navigation Algorithm

导航是目前基于位置的服务中尤为常见的一种服务。传统的导航服务应用于车辆驾驶和人们出行,而旅游业的发展对地图提出新的要求,也使得传统的导航服务不再适用。针对这种情况,提出一种可以应用于变比例尺地图上的导航算法。该算法的主要思想是坐标转换和误差减免。实验表明,该算法在变比例尺地图上误差小,能有效导航。

Navigation is particularly common in location based service. The traditional navigation is used to driving and travel. The development of the tourism industry puts forward new requirements on the map, which makes the traditional navigation service is no longer applicable.Proposes a kind of navigation algorithm which can be used on the variable scale map. The main idea of the algorithm is the coordinate conversion and deviation reduction. The results show that the algorithm has little deviation on the variable scale map, and it can effec-tively navigate.
