基于MapX的导弹攻击沙盘演示系统代码

一.  数据结构

/////////////////////////////////////////////////////数据结构////////////////////////////////
//导弹和飞机的位置
typedef struct _Position
{
    double       m_longtidude;        //经度
    double       m_latitude;          //纬度
    bool         flag;                //标识位

} Position;

typedef  std::vector<Position> _planePositionVector;    //存储飞机的轨迹
typedef  std::vector<Position> _missilePositionVector;  //存储导弹的轨迹

///////////////////////////////////////////////////////////////////////////////////////////

 

二.  接口

    //////////////////////////////////陕西测绘中心地图接口///////////////////
