How to mark a position along the road on a map

摘要

PROBLEM TO BE SOLVED: To provide a system and a method for marking a position along a road on a map and performing navigation. A system for marking a position along a road on a map and a method thereof are disclosed, and a position mark module, a position acquisition module, a position data conversion module, and a position information display module are included. Marked on the map and virtual, there is no need to stand a stand card in the field, manufacturing cost is low, manufacturing and updating speed is fast, shareable, and updating and maintenance cost is extremely low. Therefore, it is suitable for marking the position using all roads, the road name, the distance between a certain position point and the road start point, and the vertical distance to the road centerline or the vertical past the virtual road centerline. To realize a method that is marked by the distance between the line and the intersection of the actual road center line, is intuitive and easy to express, can be marked in a plane position, and can be marked in a three-dimensional space by increasing height data. Can be done. [Selection diagram] Fig. 1
