可以根据不同的椭球参数进行空间坐标系向大地坐标系的转换-Can be based on different parameters of the ellipsoid to the earth coordinate system of space coordinates conversion

用OpenGL实现正方体,台体,柱体,球体,超椭球体,环的三维创建及几何贴图-Using OpenGL to achieve cube, the Taiwan body, cylinder, sphere, super-ellipsoid, Central and geometry to create three-dimensional mapping

导航中，参考椭球定位和不同坐标系之间的转换-Navigation, positioning and reference ellipsoid between different coordinate system conversion
