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.

ItemAwareness as a foundation for developing effective spatial data infrastructures( 2006)The development of an effective spatial data infrastructure (SDI) often occurs in a fragmented organizational environment requiring a high level of inter-organizational collaboration. Different organizations from various jurisdictions needs to work together closely when agreeing on how they will jointly register, store, use and share data and how they will make their data available to the wider society. This collaboration is generally regarded as very difficult. In particular, organizational issues are considered one of the key fundamental constraints to inter-organizational sharing of spatial data. But what makes collaboration effective and successful? For example people often resist sharing data across organizational boundaries due to loss of control, power and independency. In the spatial community, the term awareness is often used when discussing issues concerned with inter-organizational collaboration. However, a major problem by using the term awareness in discussions of inter-organizational collaboration is that awareness is undefined and often misused as a term in the spatial data handling community. The (over)-use of the term awareness, without having a rigorous definition to rely upon increases the difficulty of understanding and developing collaboration issues. The difficulty in quantifying and describing issues in collaboration make the development of effective spatial data infrastructures problematic since this development should be based on a conceptual framework that clearly addresses the problems spatial organizations currently encounter. As a result, the focus of this paper is on the nature and role of awareness. It explores why and how awareness plays a fundamental role in overcoming organizational constraints and in developing collaboration between organizations. The paper discusses the concept of awareness in the area of organizational collaboration in the spatial community, explains the important role awareness plays in the development of spatial data infrastructures, and introduces a methodology to promote awareness. Furthermore, the paper aims to make people in the community more aware of the use of the term "awareness" – when to use it, how to use it and especially important, how not to use it. The paper will use land administration systems as the discipline for investigating awareness.

ItemThe development of a frameworkand associated tools for the integration ofmulti-sourced spatial datasets( 2006)The world of today heavily relies on spatial data to manage the natural and built environments.Monitoring and controlling the impact of human activities on environment and the impact of naturalenvironment changes (including natural hazards) on built environment is a major policy driver formany jurisdictions. The mitigation of natural hazards including tsunami, earthquake and landslide andsecuring citizens against them has become another priority of nations , especially after Indonesia’stsunami. September 11 was also a remarkable point in history which attracts attentions towardsproviding more efficient counter-terrorism initiatives to secure citizens.In many countries meeting sustainable development objectives including social cohesion andenvironment protection together with economical growth is the most overwhelming policy driver. Inthese countries most of legislations and decisions are made, if they meet sustainable developmentobjectives.All above mentioned activities try to control the natural and built environments and monitor theimpacts of one environment on the other one. To control and monitor built and natural environments,the components of these environments need to be integrated to provide the factual model of realworld. Effective access and use of spatial data has been addressed by developing SDIs (Spatial DataInfrastructures) which one of its objectives is to address and provide requirements for effective dataintegration.The effective integration of built and natural environmental datasets is an ultimate goal of manyspatial decision making systems which has not been fully achieved, however technical integration andinteroperability of multi-sourced spatial data have received much attention. The integration of multisourcedspatial data due to the diversity of data providers needs more than technical tools andconsiderations. Institutional, social, legal and policy requirements must also be taken intoconsideration in order to achieve effective integratio

ItemA template for assessing worldwide cadastral systems as part of national SDI initiatives( 2006)Many countries over the past few years have spent considerable time and energy in attempting to compile descriptions and reports in the area of land administration, without giving much attention to the role of cadastral systems and national spatial data infrastructures within a land administration system. The Permanent Committee on GIS Infrastructure for Asia and the Pacific (PCGIAP) and the International Federation of Surveyors (FIG), together with the Centre for SDIs and Land Administration have attempted to address this through the creation of a joint cadastral template that has so far been filled out by 39 countries. The template collects descriptions of national cadastral systems as part of National Spatial Data Infrastructure (SDI) initiatives on a broad basis and the information is made publicly accessible on the web. The information can be used for comparing and assessing land administration and cadastral systems worldwide, in order to help countries re-engineer and implement their systems to address future needs. This paper aims to outline the concept and theory behind the development of the cadastral template and its relationship with National SDI initiatives and how it can help spatial information practitioners in improving and re-engineering their infrastructure and systems. Analysis of the data gathered from the completed templates is currently being undertaken with some overall results presented and future areas of work identified.

ItemSpatially enabling governments: a new direction for land administration systems( 2006)Most decisions involve a spatial component, though few people realize its significance. Technology is about to bring the spatial component to the forefront. A place on earth can be defined with precision on the ground and in computers. Digital data can be attached to a location as never before. Spatial identification and location enablement applications are now available in every significant type of software (word processing, spread sheets, professional applications, Web systems, GIS and databases). Use of appropriate computers with interpretative software capacity now transforms computer language into understandable descriptions of places, Governments, business and communities can potentially use computers to identify “where” their policies and activities are happening. More significantly, the “where” component can be used as an organizing structure for most human activities and information. The challenge of these new technological and organizational opportunities is large. A nation’s ability to reap the benefits of the spatial enablement of information requires the highest level input from its government and private sectors. Land administration systems (LAS) are the traditional means of spatial organisation of information: they are the obvious starting point for assessing new technologies in the context of different demands for land information for modern governments. This potential to transform the ability of LAS to inform governments, business and citizens about their world led to the concept of iLand, a concept of spatially enabled information for modern government.

ItemIncorporating sustainable development objectives into land administration( 2006)Historically, land administration systems (LAS) were built to support land markets and land taxation systems. In developed countries, these systems constitute substantial infrastructure provided through government for the benefit of overall public administration, citizens and businesses. These systems are expensive to maintain and increasingly reliant on technology. The design of LAS will become even more complex as they are now being used to assist delivery of a broader range of public policy and economic goals, the most important of which is sustainable development. The national and historical methods used to incorporate sustainable development objectives into national LAS were examined in an Expert Group Meeting (EGM) in Melbourne in December, 2006 with leading stakeholders and land policy experts from Australia and Europe. Distinctions between approaches used in modern European democracies and in Australia were identified. The European approach showed more integration between the standard LAS activities and measures of sustainability. Australian policy was more fractured, partly due to federation and the constitutional distribution of powers. In contrast, Australian LAS pioneering lay in incorporating market based instruments (MBI) and complex commodities into LAS and revitalization of land information through inventive Web based initiatives. The EGM developed a vision outlined in this paper for future LAS sufficiently flexible to adapt to this changing world of new technology, novel market demands and sustainable development.
