Combining Synchronous and Asynchronous Collaboration within 3D City Models

Klimke, Jan; Döllner, Jürgen in Sixth International Conference, GIScience 2010, Zürich, Switzerland, Sep. 14-17 2010, Proceedings Fabrikant, S.I.; Reichenbacher, T.; van Kreveld, M.; Schlieder, C. ( Hrsg. ),   6292 , Springer , 2010 .

This paper presents and approach for combining spatially distributed synchronous and asynchronous collaboration within 3D city models. Applications use these models as additional communication medium - beside traditional ones like chat, audio, and video conferences - to facilitate communication of georeferenced and geospatial information. Among many challenges collaboration tools should support both the communication with other collaborators and their awareness of the current collaboration context. To support knowledge construction and gathering, we have designed a collaboration tool that facilitates (a) creation of comments that have 3D references to the virtual 3D city model and (b) information about the context in which these comments are reated. The synchronous collaboration in connection with the creation of non volatile, precisely georeferenced units of information allows users a comprehensible form of cooperation in spatially distributed settings. In our approach media breaks are avoided by using a single 3D user interface to avoid media switches and disruption in working processes. By visualizing the information associated with a geographic feature or 3D geometry of a virtual 3D city model a coherent representation of content and reference is possible.
