Delivering semantic enrichment of 3D urban models for financial and sustainability decision support

Management of large urban projects requires complex decision-making, which involves a large number of actors. Decision-makers, urban planners, designers, contractors usually have different backgrounds and qualifications. Such a diversity of may lead to conflicting goals,opinions and wrong expectations, which can make the decision-making process inefficient. In many cases, the actors might experience problems understanding each-others position, reasoning or even used terminology. Therefore, tools that support consultation and interaction in the best way is vital for the success of urban projects. This paper describes an 3D ontology based software system that has been used for several years now in more than 50 urban development projects. The paper tries to evaluate it objectively. In addition the paper tries to explain why a small enterprise like StrateGis sees Semantic Technology as very important for their future business but also struggles to adopt it.OTB ResearchOTB Research Institute for the Built Environmen
