Abstract

Horizontal and Vertical Hachures
Track: Cartographic Design
Authors: Patrick Kennelly

Two methods are presented to hillshade using horizontal and vertical hachures. Horizontal hachures begins with closely spaced contour lines, which are then iteratively buffered, clipped and selected to match the tonal variations of hillshading. Vertical hachures orient point symbols in the aspect direction, drawing black and white lines on the shadowed and illuminated sides of the terrain respectively. Both methods result in stylized terrain maps with unique three-dimensional appearances.
