有没有百度转凯立德的
// 此接口当输入坐标为**大陆以外时,仍旧返回WGS-84坐标
// + (CLLocationCoordinate2D)wgs84ToGcj02:(CLLocationCoordinate2D)location;
底层实现中,这种简单的矩形范围判断,会把某些国家的区域误判为**:
想问下有什么办法判断坐标 是否在国内?
我测试了这个算法的Java版,bd09相关的转换方法的误差极大。
同时测试了类似算法的Java版,误差很小。
比较了两者的代码,唯一的不同就是一个常量,你这里全部使用的M_PI
,他那里bd09相关转换使用的var x_PI = 3.14159265358979324 * 3000.0 / 180.0
。
你这里是不是写错了?
