This presentation will discuss the recent advancements in video card technology and its contribution to Web GIS 3D visualization. Rapid, accurate, and robust 3D visualizations can now be generated on demand from native GIS data. Todays commodity graphics processing unit (GPU) technology, most notably driven by the game industry, continues to double its performance every six months. It increasingly provides the performance, throughput, and fidelity to visualize and analyze both 3D and 4D geospatial data. Integrating these modern visualization techniques with Web GIS is in its relative infancy. This discussion will focus on our integration of both ArcGIS Engine and an embedded browser engine with this GPU technology. Embedding ArcGIS provides the integration platform that ensures interoperability across projects, geodatabases, and broader enterprise solutions. The browser engine provides the inherent mechanism to mash up, discover, analyze, serve, and leverage the momentum of Web GIS. Examples of rendering and symbolizing datasets, ranging from the realistic to the thematic, will be provided.
