medium scale maps

In this paper, the author thinks that map scale must be accordance with map projection, and is the length ratio, which is included in cubic ratio,and analyses the conic projection and gives some suggestion.

对于地图比例尺,教材上一般沿用平面长度比例和运用投影将地球椭球体缩小后表示在平面的体积比例概念,本文认为地图比例尺是一个必须与地图投影原理相统一的,存在于体积比例之中的长度比例问题,并以圆锥投影进行了分析提出商槎。
