Tanaka Contours Package

Description

The tanaka package is a simplified implementation of the Tanaka method. Also called "relief contours method", "illuminated contour method", or "shaded contour lines method", the Tanaka method enhances the representation of topography on a map using shaded contour lines. North-west white contours represent illuminated topography and south-east black contours represent shaded topography.
