To achieve the goal: the Baidu map latitude and longitude conversion to the Tencent map/google corresponding latitude and longitude degree. Method 1: Use code to convert The problem: After the conversion, the error is large, basically not available public static void convert_bd09_to_gcj02 (double lat, double LNG) { double x_pi = Math. PI * 3000.0/180.0; Double x = lng-0.0065, y = lat-0
