Virtual 3D City Models as Foundation of Complex Urban Information Spaces

Abstract

Virtual 3D city models represent spatial and geo-referenced urban data by means of 3D geovirtual environments that basically include terrain models, building models, vegetation models as well as models of roads and transportation systems. In general, these models serve to present, explore, analyze, and manage urban data. As a characteristic element, virtual 3D city models allow for visually integrating heterogeneous geoinformation within a single framework and, therefore, create and manage complex urban information spaces.
