In this paper we show how to efficiently integrate traditional GIS data into terrain models in order to generate complete 3D maps with little overhead for textures. The results meet the requirements for the Web 3D Service (W3DS), a proposal for the standardization for delivering 3D web maps. Our approach is designed to create fully vectorized 3D scenes that deliver the best possible quality and...

Figure 1. Architecture and components of the interdependent suite of infrastructure simulations developed at Los Alamos National Laboratory. The social-contacts network at the lower left is a fragment of the complete network and is obtained by looking at a single family (center) and tracing their contacts up to distance 3, which involves considering all nodes in the graph within distance 3. The...
