Resumen

Advances in cartography: towards the third dimension
The last fifteen years have witnessed an authentic revolution in the field of cartography, and specially in the three dimensional characterization of territory. The change is founded, undoubtedly, in improvements in the field of geographical positioning —global positioning systems— in that of the massive catchment of
geographical data —with the development of aero-transported sensors that are increasingly more exact and powerful, like satellites and radars— and in their management —with the development of geographical information systems (GIS) and digital elevation models (DEM)—. From our perspective, four things have fundamentally changed: the way in which information is gathered, the degree of accuracy, the size of the geographical space reached and the popularization and diffusion of cartography
