My research career has so far spanned a wide variety of software-related areas: computer vision, computer graphics, geographical visualization, distributed geographical information systems (GIS), and now infrastructure for human collaboration. I will present some these projects in reverse chronological order.

• NODAL: A System for Ubiquitous Collaboration
• SRI's Digital Earth Project, which includes:
• The GeoWeb: Bringing Location to the Web…
• TerraVision: Distributed, interactive 3D Terrain Visualization.
• GeoVRML: 3D Geographic Modelling in VRML/X3D.
• UBC Robocup: Thunderbots
