三维地图的机助制图试验

Some Experiments on Three-dimensional Map

    摘要
  • 摘要: 作者指出三维地图正在逐渐得到广泛使用,其原因是:1.许多制图物体具有三维表面,而就制图手段而言,三维地图能显示所表示物体的本来面目。2.从地图感受论来说,用透视方法制成的地图能较好地符合人们对实在的观察,因此这种地图具有更多的直观性而读者能便于获得具体印象。其次这种地图易于用机助制图方法制作。本文中指出若干不同题材的三维地图例子。是在美国北达科他州立大学地理系实验室用IBM 370/158计算机和Calcomp自动绘图机用机助制图方法完成的。

     

    Abstract: In this paper some examples are made to show 3-dimensional maps with different topics.These are made by the computer asisted cartographic method with IBM 370/158 computer and Calcomp ADM in the Lab of Geography Department of UND(University of North Dakota).Nowadays three-dimensional maps are gradually used on a larger scale.The reasons are as follows:1.Many cartographic objects have 3-dimensional surfaces,and a 3-dimensional map,so far as cartographic means is concerned,can reveal the natural feature of the object represented.2.From the viewpoint of cartographic conception,maps made by perspective methods are in beter coincidence with man's view to the reality,therefore map readers can get a concrete impresion easier.Moreover,it is easy to make by means of computer asisted cartography.
