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. This chapter explores 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 utilize them as a source for the computer assisted treatment of morphometric topics. The chapter describes the logics of a computer program named 'HACHURE' as developed by the author. It computes hachures which can then be drawn by a plotter either in the form of 'slope hachures' or 'shadow hachures' according to the decision of the program user. 'Cartographic drawing with computers', which interpolates and stores temporarily an array of points lying on a smooth curve which passes through the given array.
