高斯投影的正解算法，用c++实现的，在vc环境下，中央经线是117-Positive Solutions of Gauss projection algorithm, implemented with c++, vc environment in the central meridian is 117

测绘学中的高斯投影正反算，输入大地坐标相应参数，通过正算可得到高斯平面坐标；或输入中央子午线经度经反算得到大地坐标相应参数。-Gauss projection forward and backward count in geomatics. Input geodetic coordinate parameters,click direction algorithm ,user can get gauss plane coordinate or input Central meridian lon

大地测量学坐标正反算，可以选择不同的坐标系，设置中央子午线，进行大地坐标和高斯投影坐标之间的转换-Geodesy coordinates reverse calculation, you can a different coordinate system, set the central meridian, convert geodetic coordinates and Gauss projection coordinates between
