双曲型经线等面积伪圆柱投影族的研究
On Family of Hyperbola-Longitude Equalarea Pseudo-Cylindrical Projection
-
摘要: 构建了一个纬线表象为平行于赤道的直线,经线表象为对称于中央直经线的双曲线,且面积没有变形的投影集合,并得到一组概括公式。该公式不仅包括了克拉斯特创建的经线交于极点的双曲经线等面积伪圆柱投影,而且也包括了经线交于极线的双曲经线等面积伪圆柱投影。Abstract: An equalarea pseudo-cylindrical projection gather is constructed,in which the longitudes are hyperbola being symmetrical to the central meridian and the latitudes are parallel lines.A generalized formula is also derivated.
