Abstract
In this paper we present a key data structure and associated render-time algorithm for the combined display of multi-resolution 3D terrain and traditional GIS vector data, by combining a fast GPU-based terrain solver, which is designed to create fully 3D scenes that deliver the best possible quality and do not require dynamic texture generation and handling. Level of detail terrain models and vector maps are created, and the server-client architecture is presented. The application provides an effective way for powerful access and manipulation of large-scale real datasets, which represents a basic mechanism for 3D GIS interface and exploration tools.
