如何将GPS坐标转换为XY平面坐标（简易转换）
/* 经纬度坐标点（84坐标系） */public class GePoint {private double latitude; // 纬度坐标private double longtitude; // 经度坐标public GePoint() {}public GePoint(double latitude, double longtitude) {this.latitude = latitude;this.longtitude = longtitude;}public double getLatitude() {return 2 * latitude * Math.PI / 360 ;}public void setLatitude(double latitude) {this.latitude = latitude;}public double getLongtitude() {return 2 * longtitude * Math.PI / 360;}public void setLongtitude(double longtitude) {this.longtitude = longtitude;}}
