摘要：Three-dimensional visual databases, created for landscape or 3D map visualisations, consist of integrated data sets including DTMs, orthorectified aerial or satellite images and optionally topographic or thematic maps. Objects models of man-made objects like buildings might be linked to those databases as well as models of natural objects like tree representations. If those databases are optimised for visualisation purposes they generally do not allow for GIS typical analyses or queries. But more and more tools based on those databases are developed which allow for 3D photorealistic visualisation of corresponding virtual landscape or city models. Viewers allow to interactively navigate in the scene or to enable users to virtually participate in simulated events.
