高斯投影大地坐标正解算源代码，供大家参考一下。呵呵。-Geodetic coordinates are Gauss projection solver source code for your reference. Oh.

Matrix transformation, projection, blanking, rendering (just by light and plane Angle to determine the brightness of the plane

A computer application that performs cartographic projection between the WGS and Merchich cordoned systems.

Algorithm optimization is very good, almost no circulation, Principal component analysis of multivariate data analysis projection, FMCW frequency modulated continuous wave radar range and angular measurements.
