  • Mars coordinate system (GCJ-02) and Baidu coordinate system (BD-09) conversion algorithm: http://blog.csdn.net/coolypf/article/details/8569813 (interpretation: International latitude and longitude coordinate standard for WGS-84, The country must use at least the GCJ-02 developed by the National Bureau of testing, the location of the first encryption. Baidu coordinates on this basis, carried out the BD-09 two times encryption measures, more protection of personal privacy. The coordinate system of Baidu external interface is not the true latitude and longitude of GPs acquisition, and it needs to be transformed by coordinate transformation interface. )
