Abstract
This study is to solidify a Topographic map by using a computer, and to consider the method when expressing as a bird’s-eye view viewed from the sky. Objects are the Tanzawa-mountains and its surrounding area, and it’s aim is to draw up a bird’s-eye view as a mountain map. Because it’s one of the character of a bird’s-eye view to be able to express conditon of topographical ups and downs. On the other side, the fault that it’s causing the fault in a Bird’s-eye view to be able to express by the Topographic map as a plan view also exists. I draw up it while examining those contents.
