以球面椭圆坐标为参数的等角投影的探求

AN EXPLORATION OF THE EQUAL-ANGLE PROJECTION WITH SPHERICAL ELLIPTIC COORDINATE AS PARAMETERS

本文利用等量坐标与等角投影之间的关系,以Guyou椭圆坐标为例,求得其等量坐标,并进一步导出相应的等角投影方程。该方法为新投影的探求,开辟了广阔的前景。

This paper uses the relation of isometric coordinate and equal-angle projection, with Guyou elliptic coordinate as an example, seeks its isometric coordinate, and then deduces its equal-angle projection equation. This method blazes a trail for the exploration of new projections.
