Abstract
During recent years, a lot of projects using new technologies have been developed in the field of geoheritage. This chapter aims to present how digital technologies can be used for geoconservation and interpretation. While large amounts of digital data (visual, dimensional, locational or environmental) can be recorded to monitor heritage, the emergence of virtual visualisation has been experiencing the greatest development in recent years. Cutting-edge geovisualisation using high-resolution images or 3D representation techniques allows the acquisition of accurate digital models. These virtual models of natural environment can be used to prevent natural hazards in touristic geosites, such as rockfalls in Yosemite National Park, to keep a digital archive of vulnerable sites as in the Valley of Geysers in Kamchatka, to produce cave replicas as for the Chauvet cave in France, or to augment reality for geotourists as in the project GeoGuide. Beyond the quality of virtual models produced, many questions remain concerning production costs, data reliability and longevity, user’s engagement and the ‘sense of place’ of virtual geoheritage.
