ItemSpatially enabled society(International Federation of Surveyors (FIG), 2011)The term 'spatially enabled society' describes the emerging cultural and governance revolution offered by pervasive spatial information technologies and spatially equipped citizens. Spatially enabled societies make possible, amongst many other things, sustainable cities, GFC early warning systems, smarter delivery of housing, improved risk management, and better macroeconomic decision making. The concept is not about managing spatial information, it is about governing society spatially. Spatially enabled societies represent the realization of the promises offered by building spatial data infrastructures (SDIs) and reforming land administration systems. These building blocks, established over decades, make possible spatially enabled societies. Without tools for managing metadata, building complete national cadastres, modelling and integrating the 3rd dimension, and much other foundational work, spatially enabled societies cannot emerge. This paper explores the notion of spatially enabled societies further. Example applications are used in the discussion. The paper also demonstrates how, despite the grand possibilities of revolutionary spatial technologies and spatially aware citizens, existing infrastructures including SDIs and land administration system will still require an ongoing governance structure for spatially enabled societies to be maintained.

ItemAdvanced principles of 3D cadastral data modelling(FIG, 2011)Current cadastral data models use a 2D land-parcel definition and extend it to cover 3D requirements. This approach cannot adequately manage and represent the spatial extent of 3D land rights, restrictions and responsibilities (3D RRRs). This paper aims to develop a 3D Cadastral Data Model (3DCDM) to configure 3D cadastral frameworks, manage and represent 3D RRRs, and facilitate 3D cadastre implementation. Three underlying principles have been proposed to develop the 3D Cadastral Data Model (3DCDM). These principles are: • Principle 1: The 2D cadastral data model is a sub-set of the 3D cadastral data model, • Principle 2: The 3D cadastral data model should not only accommodate 3D RRRs and their association with physical objects: the data model should also represent the spatial extent of 3D RRRs, and; • Principle 3: The 3D cadastre data model should cater for a broad range of land administration functions including land tenure, land value, land use, and land development with sufficient detail. These principles are used to assess and modify the core cadastral data model. Additionally, principles related to the legal property object are also used to modify the 3DCDM. The legal property object combines interests and its spatial dimension into a single entity. This creates more flexibility and enables inclusion of complex commodities and all kinds of RRRs. The first version of a 3D Cadastral Data Model (3CDM_Version 1.0) is provided at the end of this paper. 3DCDM maintains both legal and physical parts of 3D objects. The data model has wider application than the traditional requirements of cadastral systems: it is also usable in applications such as urban planning and disaster management.

ItemLessons for federal countries that have state land registries: the Australian experience( 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.

ItemA better way to manage land information(The Intermedia Group, 2010)Australia’s Federal Government has no constitutional authority over land administration. Each state and territory has its own system and, to date, this system has served the nation well. Each system is reflected in the historic, independent pattern where each jurisdiction computerises its own processes and operates according to its own timetable, needs, reporting functions, customer service design and other imperatives. However, the country’s capacity to meet increasingly national issues – such as management of the macro economy, a national property market, climate change response, disaster management, national business coordination and national security– is problematic. Seamless information about landownership, and its use, value and development is essential to the strategic planning of capital cities. Processes such as levying capital gains tax, allocating drought relief, and managing crime and terrorism all require broad strategic planning, as do the development of early warning systems for emergencies and climate change initiatives. As a consequence, national priorities that rely on information about land are faced with the technical, policy and institutional barriers that come with integrating data from multiple state-based sources. The solution is a national land information infrastructure.
