VISUALISATION AND PRESENTATION OF THREE DIMENSIONAL GEOSCIENCE INFORMATION

Advances in computer technology have provided the opportunity to present geoscience information in new and innovative ways. The use of web-based three-dimensional interactive models, animations and fly-throughs significantly enhances our ability to communicate complex geometries and concepts not only to the geoscientific community but also, just as importantly, to the general public. Projects within Geoscience Australia currently use a range of GIS, remote sensing, and modelling packages for visualisation of fundamental and derived data. In the main each of these packages also has the ability to produce, as an output, some form of model or animation sequence displaying the results of the visualisation. In most cases however, these outputs are generally not of sufficient quality or do not provide adequate functionality without further processing or editing. Geoscience Australia has adopted a multi-disciplinary approach to 3D visualisation encompassing cartography, GIS, remote sensing, graphic design, programming, web, and video editing to the post-processing of these visualisations. This paper examines the benefits of using models and movies for the visualisation of geoscience and briefly discusses the current workflows and presentation techniques used by the Geo-Visualisation team within Geoscience Australia.
