3D visualisation of spatial information and environmental process model outputs for collaborative data exploration

Increased access to consolidated digital spatial data via spatial data infrastructures (SDI) is advancing the potential for spatial analysis applications such as environmental process modelling. While a number of expert visualisation packages exist for environmental models, there is a lack of widely available interactive visualisation tools. To provide for greater community engagement, virtual environments that are online, collaborative and can run on low-cost PCs are required. This paper discusses the development of a tool which aims to provide both expert and non-experts with access to environmental process model outputs. Conversion from standard format GIS data, into a game engine has been achieved. A methodology for mapping the effects from environmental model outputs into the virtual environment has also been shaped. Development of a 3D object library, for vegetation and other matter, implementation of the tool on a network and specification of criteria for display and communication options in a multi-skilled environment are the current focus. Envisaged system use scenarios have been devised in collaboration with national and state agencies, who are the clients for this research.
