+ * WGS84坐标系：即地球坐标系，国际上通用的坐标系。设备一般包含GPS芯片或者北斗芯片获取的经纬度为WGS84地理坐标系。
+ * 谷歌地图采用的是WGS84地理坐标系（中国范围除外,谷歌中国地图采用的是GCJ02地理坐标系。)
+ * <p>
+ * GCJ02坐标系：即火星坐标系，WGS84坐标系经加密后的坐标系。
+ * 出于国家安全考虑，国内所有导航电子地图必须使用国家测绘局制定的加密坐标系统，即将一个真实的经纬度坐标加密成一个不正确的经纬度坐标。

+ * BD09坐标系：即百度坐标系，GCJ02坐标系经加密后的坐标系。搜狗坐标系、图吧坐标系等，估计也是在GCJ02基础上加密而成的。
