ItemA new vision on cadastral data model( 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.

ItemNational land information infrastructure through a collaborative framework(International Federation of Surveyors (FIG), 2012)Australia is being faced with issues which demand a national focus. These issues include natural resource management, land markets, trading in commodities such as water and carbon, and the development of national policies for housing and infrastructure. Businesses also are demanding a more national approach as an increasing number of businesses now operate nationally. This is reflected in the Australian Bureau of Statistics figures which show the number of businesses operating in all states and territories increased by 70% between 2003 and 2007. Over the past several years considerable effort has been directed by the Australian Government towards the development of a “seamless economy” to improve productivity across its federated system of government. In this environment, Land administration in Australia is also jurisdictionally based with no national infrastructure capable of delivering the land information necessary to meet Australia’s needs. In the past, this jurisdictional based approach to land administration has satisfactorily served Australia in an environment where the vast amount of service delivery by both business and government was state focused. Each jurisdiction has taken advantage of the ongoing technological developments to enhance their respective systems and it would appear that many of the needs at a jurisdictional level continue to be met. Whilst land administration has not featured specifically in this reform several of the nominated projects involved land in some form. To respond to the national drivers, this paper aims to introduce a collaborative framework for the implementation of a national land administration infrastructure which relies on the state and territory based systems as its primary source of information.
