Illustrating the Concepts of the Contour Symbol,Interval, and Spacing VIA 3-D Maps

Abstract

Although topographic maps are commonly used, few readers seem to understand them adequately. In this paper we attempt to develop a teaching strategy to remedy this deficiency. The teaching strategy is founded upon a group of integrated illustrations which take the reader from data-gathering through to the final map. We believe that these illustrations are simple enough to be understood by grade school children, yet sophisticated enough to satisfy adults.
