    A new vision on cadastral data model
    Kalantari, Mohsen ; RAJABIFARD, ABBAS ; WALLACE, JUDE ; WILLIAMSON, IAN ( 2006)
    Land administration systems are evolving towards an integrated land management paradigm designed to support sustainable development. In this paradigm, land administration delivers four functionalities: land mapping, land registration, land valuation and land development, each with specific data elements, with the cadastral data model at the core. Cadastral data modelling potentially plays a key role in both data and business management in modern land administration systems. However, some modifications to existing data models could potentially improve their capacity to deliver sustainability. Firstly, the existing role of land parcels and properties as core building blocks in land administration systems can be significantly extended to make the cadastral fabric available to assist management of a wider range of rights, restrictions and responsibilities by using the concept of legal property objects: an entity defined by a law or regulation which relates to a physical space on, below or above the earth. This can be interpreted as a new land related commodity, land parcel or a property. Secondly, although land parcel and property identifiers are key elements of interoperability within land administration subsystems, the paper argues that they have not yet given appropriate emphasis in cadastral data models. Among the identifiers, spatial identifiers can potentially simplify data exchange and work flows among land administration functionalities on a much wider basis. Finally, the paper discusses technical issues raised by changing the cadastral model: the advantages and disadvantages of spatial identifiers, possibilities for spatially presenting rights restrictions and responsibilities, and consistency between various legal property objects.

    Integrated land administration in Australia : the need to align ICT strategies and operations
    Bennett, Rohan ; WALLACE, JUDE ; WILLIAMSON, IAN ( 2005)
    A modern Land Administration System consists of four key functions: land tenure, land valuation, land use and land development. The integration of these functions and associated land information are essential if we are to achieve sustainability objectives and a more efficient property development process. Historically many countries have divided up their key functions; the advent of information and communication technologies [ICT] offered the possibility of integration. Current research suggests that land administration functions have resisted integration, despite technological advancements. This paper analyses such findings by considering the land administration functions of Victoria, Western Australia and New South Wales. It considers each state’s spatial-mapping and registry functions at a strategic and operational level. Particular attention has been given to ICT policy and operations. The study suggests that many factor shave obstructed integration, including historical backgrounds, politics and disparate organizational cultures have all played a role. Another important factor has been the failure to align the ICT strategies and operations of the different functions: land registries have tended to view technology as supporting core operations rather than core strategy. Conversely, spatial-mapping units see ICT as fundamental to operations and strategy: not only has ICT enhanced traditional practice, but it has also allowed for the creation of new products and services. It is argued that in order to achieve further integration, Land Administration functions must align their perception and use of ICT. Shared leadership, integrated ICT infrastructures and government mandates will assist this alignment.

    Transferring our knowledge and systems: tenure formalisation
    Dalrymple, K. ; Wallace, J. ; Williamson, I. P. ( 2005)
    Land administration systems are key infrastructure for national growth. They deliver macroeconomic growth, allow greater market integration, provide security of tenure and investments, and increase the capacity to deliver welfare. However, land administration systems supporting these activities are complicated and limited. While advanced tools and principles may be borrowed by countries building local land markets, every situation requires innovative solutions in response to the unique and dynamic land administration environment. Project designs must capture a wide range of people to land relationships and different socio-environmental circumstances. An investigation of different people to land and natural resource arrangements was conducted in a development scenario. Case study investigations took place in three rural villages in Cambodia undergoing different stages of land administration project implementation. These studies revealed a wide set of indispensable informal tenure arrangements outside the design scope for providing formal tenure security. From 1990 to now, land projects design emphasis has moved from technological to institutional criteria. Further design change is still required, especially to deliver sustainability and social development. In particular land administration systems used in development scenarios must approach formalization of land tenure with more innovative approaches. This may also require an expansion of tenure security options beyond those currently included in formal systems. Formalised Western skills may be advantageous for delivering some services, but they must be complimented by a holistic understanding of local culture and capacity.

    A toolbox for mapping and managing new interests over land
    BENNETT, ROHAN ; WALLACE, JUDE ; Williamson, Ian Philip ( 2008)
    The drive for sustainable development has led governments to create new interests over land. The role of cadastral and registration systems in the mapping and management of these new interests is unclear. Whilst these systems have always played an important role in the administration of land parcels and ownership, the new land interests are increasingly being mapped and managed elsewhere. As a result administrative inefficiencies and transaction complexities are growing. Existing cadastral and registration systems have the capacity to improve the situation; however, a guiding framework for their inclusion is needed. This paper introduces a framework of principles that articulate the roles of cadastres and registration systems in the management of new land interests. Importantly the framework is holistic and reflects other components essential to good land administration. These include the roles of land policy, legislation, flexible tenures, institutions, spatial data infrastructures and capacity building. The principles will systematize the management of land interests across different jurisdictions.
