This work is about the cartographic preparation and edition of digital elevation models. In that way systematic and non systematic errors were evaluated and also the limitation of current geographic information systems software for creating appropriate cartographic representations. In that context shadow relief techniques are discussed and evaluated and it is also was developed a technique for the application of Imhof palette in a lineal non proportional three segment color hypsometric ramp. As a result a more clear and richer representation was obtained.
