This master thesis develops a software tool that aids architects in the process of urban analysis. The tool complements an urban 3D model with data from the Google Maps database, generating an “urban information model” in the process. The topics of urban analysis reach from the function of the building and time of building activity to the location of public transportation stations and density of services in the urban area. The generated charts and graphs assist the architect in the formulation of a hypotheses about the unknown urban area, making the software a practical tool for architectural competition design. First, the requirements for such an urban analysis toolare defined. A conceptual system design lays out the foundation for a software tool that can meet these requirements. The elaboration of these assets leads to the implementation of the urban analysis tool concept. A case study in Vienna and London test the capabilities of this prototype. Both case studies show that the software tool can give the architect a good overview of several cultural aspects in the urban area.
