Topographical relief depiction by hachures with computer and plotter

Abstract The introduction of lithographic reproduction methods for printing of maps instead of copper engraving techniques almost 150 years ago, has supplanted the use of hachures for cartographic relief depictions. The article explains how computers and plotters can be used to produce hachures based on an initial input of digital terrain models. Instead of using hachures, as in the past, as a possible means of topographic relief presentation only, it is suggested to utilise them as a source for the computer assisted treatment of morphometric topics.
