Virtual Australia and New Zealand (VANZ): Creating a piece of Digital Earth

VANZ is an Initiative of a wide group of research, government, industry, technology and legal stakeholders in Australia and New Zealand. Its purpose is to broker development of the 'Authorised Virtual World' that brings together 3D Spatial and Building Information Modelling within a proposed new Legal Framework. The aim is to create an 'authoritative' and 'enduring' 3D model of both the 'physical attributes', and 'legal entitlements' relating to every property. This 'authorised virtual world' would be used in all 'property-related' activities – to deliver better, quicker and cheaper outcomes. It would also be used as the context for serious games and to model dynamic processes within the built environment, as well as for emergency response and disaster recovery. Productivity savings across Australia have been estimated at $5 billion pa for the design and construct phases alone. The problem for owners, bankers, insurers, architects, engineers and construction companies, and others, is that they require access to 'authoritative' and detailed 3D data for their own purposes, that must also be securely shared with others up and down the 'property' chain, and over time. All parties also need to know what are the rights, responsibilities and restrictions applying to the data, as well as to the land and buildings that it models. VANZ proposes the creation of a network of Data Banks, to hold the 'authoritative data set', 'in perpetuity', along with the associated software and virtual hardware used to model it. Under the proposal, rights of access to the 'authoritative data' will mirror each person's rights in the property that the data models. As more and more buildings are modelled (inside and out), privacy, security and liability become issues of paramount importance. This paper offers a way for the global community to address these issues. It is targeted at all who have an interest in the practical implementation of Digital Earth for the built environment – including new business opportunities worth $billions
