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。)

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。

Method Detail

values

public static GeoType[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (GeoType c : GeoType.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static GeoType valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
