This seminar will report on some explorations with online virtual reality (the free and open source OpenSimulator) in various geographic contexts. First is a comparative usability study of VR when applied to an urban (subdivision) design scenario in Dunedin, New Zealand. In this example, VR was compared against other tools commonly used in urban design, namely GIS and CAD. Second is the educational use of OpenSim as the basis for 3D geographic representation (and other interface building) assignments forming part of a postgraduate course on geovisualisation. Finally, a time-geographic (space-time cube) representation of a journey across the United States that has a photo strip narrative following the spatiotemporal data plotted in xyt space will be outlined.
