Resumen
This paper attempts to show the great changes in natural and urban environment geo-visualization that have taken place over recent decades. It emphasizes the role of 3D geo-visualization as applied to every territorial and environmental discipline, where 3D displays and then the addition of the temporal dimension (4D) have provided new windows for visualization, up to and including real time products. Increasing overall digital geo-data production, access to the Digital Elevation Model along with the contributions made by new sensors (remote sensing, Lidar, GPS, etc), the new possibilities offered by 3D software (GIS, CAD, etc) and the way in which web-based 3D viewer has become popular (virtual globes and cities), all these have offered new opportunities for the technical trained as well as for scientists and even the citizen in the street, we are told. Further to the afore-mentioned, the author sees easy access to multi-temporal geo-data (especially via OGC interoperable services and NSDI), the worldwide installation of fi xed or satellite-based sensors for geo-data monitoring, as well as the new data obtained from the citizens through internet (web 2.0) as offering new opportunities and applications w2hen it comes to studying natural and urban issues grounded upon multi-temporal and real time data.
