    Lessons for federal countries that have state land registries: the Australian experience
    WILLIAMSON, IAN ; BENNETT, ROHAN ; RAJABIFARD, ABBAS ; WALLACE, JUDE ( 2011)
    The federation of Australia and her states have significantly improved land information management and integration since 1982: cadastres were digitized, land registries computerized, web based GIS was incorporated, and SDIs developed. However, the risk of a Land Information Babel as espoused by Justice Kirby in 1982 still remains, particularly in the realm of land registries. Australia is now entering the era of national approaches to land registration. The proposed national eConveyancing system represents the first step. Many more initiatives will follow. This paper presents a new multi-purpose vision for Australia’s land registries. The state based systems need to continue collaboration in order to build a coherent national vision based around key registries, spatial enablement, and shared services. The power inherent in all land registry information must be unleashed. Land registries are more than simply systems for conveyancing. They are multi-purpose tools with the capacity to service society with the information needed to respond to our most pressing challenges, increasingly with a national focus. Future work must focus on building agreement for this national vision, undertaking a major cost-benefit analysis, comparing existing technical platforms, and creating awareness at higher levels of Australia’s significant land information achievements.

    Critical issues in global geographic information management - with a detailed focused on data integration and interoperability of systems and data
    RAJABIFARD, ABBAS ( 2010)
    The GSDI Association continues its support for the United Nations for taking the initiative on this critical global geographic information issue; and is willing to contribute to new arrangements to improve global geographic information management. The role of the GSDI Association, in essence, is to facilitate better global outcomes through utilisation of geographic information and spatial data infrastructures (SDIs). This role directly complements the proposal to establish a United Nations Committee on Global Geographic Information Management (UNCGGIM). The GSDI Association's view of the changes now taking place in the geographic information world and these changes exemplify convergence of technologies and disciplines. These changes need to be influenced where appropriate, and leveraged, by the global geographic information community, particularly by the United Nations. This paper presents some views related to the “critical issues in global geographic information management” and in particular a response to the following issues: - Governance: is global governance relevant and necessary? - Interoperability of systems and data - Data integration and layering, and - Capacity building and technology transfer In responding to these issues, the paper however provides a more detailed discussions on “interoperability of systems and data” and “data integration” in particular the technical and non-technical issues and heterogeneity associated with multi-sourced spatial data integration in the context of SDI.
