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 do not require dynamic texture generation and handling. We describe the mesh operations for integrating polygonal GIS data like forests, parks, buildings blocks, or streets into the terrain mesh and compare the results with a texture based approach.
