A Method of Contouring Cave Maps
Derek C. Ford

Abstract

Gradients and topographic relationships in a cave may be displayed by linking ceiling or floor points of equal elevation in different passages or rooms, with contours. Where drawn through the intervening rock the countours are inflected to show the passages as valleys or spurs, whichever is appropriate. The method is intended to give the viewer who is not familiar with a particular cave a better impression of its topography than is provided by the convental cave map.
