圆柱投影、圆锥投影和方位投影的统一数学模型及应用比较研究

The Unified Mathematical Model for Cylindrical, Conical and Azimuthal Projections and Comparative Study of Their Application

本文对3种常用投影,即圆柱、圆锥与方位投影,提出一种统一的数学模型并研究了投影变换规律。在比较研究的基础上提出了一个常规地图投影分类系统表,并在应用举例中,列出了这些投影之间的相对关系。

In this paper, a unified mathematical model for three conventional projections, i. e., cylindrical, conical and azimuthal projections, has been proposed and the rule of projection transformation is studied. On the basis of comparative study, a systematic table for classification of conventional projections is put forward. An example shows the relations between these projections.
