1 Cadastral Futures building a new vision for the nature and role of cadastres XXIV FIG International Congress Sydney, April Rohan Bennett, Abbas Rajabifard, Mohsen Kalantari, Jude Wallace, Ian Williamson Copyright The University of Melbourne 2008 Introduction In the final decades of the 20th century cadastral systems were revolutionized To remain relevant cadastral science must continue to look to the future This paper aims to begin a dialogue on the nature and role of future cadastres FIG Statement on the Cadastre Cadastre 2014 Land Administration Domain Model Multipurpose Cadastre Bogor & Bathurst Declarations Land Management paradigm Sydney, Australia, April

2 Research Design 1. Review of Cadastral Trends Multipurpose Cadastre Cadastre 2014 Cadastre and Sustainable Development SDI and the Butterfly 4. Articulation of Future Cadastres 2. Study of Future Scenarios Political Economic Social Technological Environmental 3. Analysis of Potential Cadastral Reponses Modern Cadastral Theories and Practice Prior to modern spatial information systems, cadastres primarily served fiscal or juridical functions. Land + + Records = $ or People Tax Post 1970, rapid developments in information technologies and the push for sustainable development led to new developments and applications for the cadastre Secure Owners Information Technology change force Records change force Sustainability Theory Sydney, Australia, April
