The representation of relief is a fundamental component of the cartographic process. A wide range of techniques representing the topographic variations of the earth`s surface on a two dimensional surface have been developed and these vary both in their symbolic content and in their degree of realism. In even that the Digital Terrain Models have been used since finals sixty`s decade, recently it has been increased their multiple applications and uses in different technical areas and of engineering, especially in Geographic Information Systems where they are need to data georeferencing. With this work we want to contribute in a technical, efficient and economical manner to the diverse processes that involve the usefulness of the DTM and especially to present the possibility of capturing data with a photogrammetric method alternative to the conventional method. The quality of the data source, the accuracy, the resolution and the ability to define small details, the hardware, methods and procedures to capture and processing data are the most important parameters when considering the generation of the Digital Terrain Models. 5 refs., 2 figs.
