Abstract

Planning situations are commonly managed by intensive discussions between all stakeholders. Virtual 3D city models enhance these communication procedures with additional visualization possibilities (in opposite to physical models), which support spatial knowledge structuring and human learning mechanisms. This chapter discusses key aspects of virtual 3D city creation, main components of virtual environments and the framework for an efficient communication. It also explores future research for the creation of virtual 3D environments.

Background

State-Of-The-Art Virtual 3D City Modelling

Planning procedures make use of models that show historic and present situations and communicate planned situations (Marcinkowski, 2007). Up to now, maps and physical 3D models delivered graphics for this geospatial communication. Nowadays, digital 3D presentations provide a more immersive interaction that may support understanding, cognitive processing and expanding of individual spatial knowledge bases. This main characteristic of 3D delivers important potential for an innovative geospatial communication in terms of linguistics, naïve geography, learning as well as cognitive, affective and conative communication aspects. The variations within virtual 3D city models can support this spatial communication more effectively in comparison to physical models. This situation leads to considerations of state-of-the art virtual 3D city creation, communication frameworks and actual user interfaces for virtual 3D city models.

Key Terms in this Chapter

Smart Approaches: Automation of modelling and creation processes that result in a virtual 3D city model.

Geovisualization: stands short for Geographic Visualization. The notion refers to a set of tools and techniques supporting geospatial communication and information analysis through the use of interactive maps.

Geomedia Techniques: Techniques that take account of transmitting media and user interface characteristics in order to adapt information processing and enhance the communication process.

Geospatial Communication: describes the transmission of geospatial knowledge from one person to another.

Semiotics: focuses on sign processes in order to understand the impact and usage of signs and symbols.

Virtual 3D City Models: Digitally reconstructed cities in virtual space, which enable virtual movement and analysis in three dimensions.
