They are characterized not only by their surface constructions like buildings and traffic infrastructure, but also by their underground structures. Besides human-created lifelines, tunnels and quarries, there are also diverse geological formations. All this information is important for a sustainable urban planning and utility management. The DeepCity3D project therefore aims to develop application-adaptive 3D visualization tools that integrate underground data and city models (provided in standardized formats) with advanced functionality to support decision making for stakeholders involved in urban planning, construction companies, insurance companies, architecture, or environmental protection.de3D city modelgeodata visualizationdata integrationgeographic information systems (GIS)006conference paper
