Abstract

Baidu Map provides most of the path navigation in the cities, but it has some drawbacks in small regions, such as the incomplete description, updating not timely. Sometimes it will bring misleading for us. In this paper, a campus navigation system is designed based on Baidu map API, using PHP, Java Script and xml technologies. The system can provide the basic map function and search the path navigation between any two points in the campus. First, draw the campus map in detail and cover it on the Baidu Map by using the Baidu Map API class. Then, reconstruct a campus's geographic information on the local database. At last, call the Baidu Map API Service class to draw the navigation path on the map. In this paper, in order to avoid the path spillover we proposed a method called Local Bounding Box (LBB), which solves the cross-border issues.
