1、WGS84坐标转GCJ02火星坐标

        /// <summary>WGS84坐标转GCJ02火星坐标</summary>/// <param name="Position">坐标结构体</param>/// <returns>返回GCJ02火星坐标</returns>public coord WGS84ToGCJ02(coord Position){Double lon = Position.lon;Double lat = Position.lat;if (!isInChina(lon, lat)) return Position;coord Pos = offset(lon, lat);Pos.lon = lon + Pos.lon;Pos.lat = lat + Pos.lat;return Pos;}

2、GCJ02火星坐标转WGS84坐标（回归计算）

   /// <summary>GCJ02火星坐标转WGS84坐标</summary>/// <param name="Position">坐标结构体</param>/// <returns>返回WGS84火星坐标</returns>public coord GCJ02ToWGS84(coord Position){Double lon = Position.lon;Double lat = Position.lat;if (!isInChina(lon, lat)) return Position;coord Pos = Position;coord tempPoint = WGS84ToGCJ02(Pos);Double dx = tempPoint.lon - lon;Double dy = tempPoint.lat - lat;while (Math.Abs(dx) > 1e-14 || Math.Abs(dy) > 1e-14)//回归{Pos.lon -= dx;Pos.lat -= dy;tempPoint = WGS84ToGCJ02(Pos);dx = tempPoint.lon - lon;dy = tempPoint.lat - lat;}return Pos;}

3、GCJ02火星坐标转BD09百度坐标

        /// <summary>GCJ02火星坐标转BD09百度坐标</summary>/// <param name="Position">坐标结构体</param>/// <returns>返回BD09百度坐标</returns>public coord GCJ02ToBD09(coord Position){Double lon = Position.lon;Double lat = Position.lat;Double x = lon;Double y = lat;Double z = Math.Sqrt(x * x + y * y) + 0.00002 * Math.Sin(y * baiduFactor);Double theta = Math.Atan2(y, x) + 0.000003 * Math.Cos(x * baiduFactor);coord outPos;outPos.lon = z * Math.Cos(theta) + 0.0065;outPos.lat = z * Math.Sin(theta) + 0.006;return outPos;}

4、BD09百度坐标转GCJ02火星坐标（回归计算）

        /// <summary>BD09百度坐标转GCJ02火星坐标</summary>/// <param name="Position">坐标结构体</param>/// <returns>返回GCJ02火星坐标</returns>public coord BD09ToGCJ02(coord Position){Double lon = Position.lon;Double lat = Position.lat;Double x = lon - 0.0065;Double y = lat - 0.006;coord Pos;Pos.lon = x;Pos.lat = y;coord tempPoint = GCJ02ToBD09(Pos);Double dx = tempPoint.lon - lon;Double dy = tempPoint.lat - lat;while (Math.Abs(dx) > 1e-14 || Math.Abs(dy) > 1e-14)//回归{Pos.lon -= dx;Pos.lat -= dy;tempPoint = GCJ02ToBD09(Pos);dx = tempPoint.lon - lon;dy = tempPoint.lat - lat;}return Pos;}
