ItemBridging SDI design gaps(Centre of Geo-Information Technologies (cGIT), 2006)The environment we inhabit is integrated and to properly manage the environment it is necessary to look at all environmental components and making multi-criteria decision about environment mostly needs an integrated view of built and natural environmental components to better interpret it.Despite the integrated nature of environment and requirements of users to integrate different components of environment, information about different elements of environment is being collected and managed by fragmented agencies under different and mostly inconsistent policies and standards to satisfy their own needs –for a single discipline- with little attention to the broad range of users – a multi-disciplinary approach. This fragmentation results in heterogeneity of technical and non-technical issues surrounding integration of datasets.An SDI is an initiative to facilitate the cooperation among all stakeholders and the interaction with standards and technological components and one of its objectives is to facilitate the integration of multi-source spatial data sets.This paper aims to address different issues connected to the integration of multi-source data sets in order to better serve different communities through their SDI initiatives and also a better management and sharing of their spatial data. The paper aims to discuss both technical and non-technical issues related to the integration of multi-source data sets in alignment with an ongoing research project devoted to developing models, guidelines and associated tools to facilitate the integration of multi-source datasets within an SDI.

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

ItemThe role of sub-national government and the private sector in future Spatial Data Infrastructures( 2006-08)A Spatial Data Infrastructure (SDI) facilitates and coordinates the exchange and sharing of spatial data between stakeholders in the spatial data community. With this objective in mind, countries throughout the world are developing SDIs to manage and utilise their spatial data assets more effectively. These countries are developing SDIs to assist in various kinds of decision-making at different levels of government jurisdictions that have an important impact within their national boundaries. However, current research shows that SDI is understood and described differently by stakeholders from different disciplines and different jurisdictional levels. Therefore, in many cases SDI initiatives remain very much an innovation even among practitioners. There are still uncertainties regarding the benefits and identities of SDIs, particularly in connection with how they evolve over time to meet user needs.This paper reviews and assesses the development of SDIs throughout the world over the past fifteen years and the leadership role of national governments in SDI creation. This assessment is based on the SDI activities of various jurisdictions including Asia-Pacific, Australia, North America and Europe and research into the worldwide effects of spatial information clearinghouses. This assessment includes a discussion on emerging trends in SDI development, with particular reference to the increasingly important role played by sub-national governments and the private sector within the framework of SDI development. The paper concludes with a discussion of the implications for future SDI development, including the delivery of a virtual world that has a particular focus on facilitating decision making at a community level within a national context.

ItemAssessing the worldwide comparison of cadastral systems(Elsevier, 2006)There is growing interest internationally in land administration and cadastral systems and especially in their role as part of a national Spatial Data Infrastructure (SDI). The important role the cadastre plays in supporting sustainable development is also well recognised. Both developed and developing countries accept the need to evaluate cadastral systems to help identify areas of improvement and whether their systems are capable of addressing future needs. Countries are continually re-engineering and implementing various aspects of the cadastre, comparing systems and trying to identify best practice within nations of the same socio-economic standing.In order to address this need, members of a team from the Centre for Spatial Data Infrastructures and Land Administration at the Department of Geomatics, the University of Melbourne, with the support of the United Nations Permanent Committee on GIS Infrastructure for Asia and the Pacific (PCGIAP) and the International Federation of Surveyors (FIG), have developed a cadastral template. The template aims to assist the evaluation and benchmarking of cadastral systems and the role they play in spatial data infrastructures.This paper aims to outline the concept and theory behind the cadastral template as well as analysing the results from 34 completed country templates. Several indicators have been used to analyse and benchmark countries cadastral systems, results of which will contribute to an improved understanding of the complex relationship between cadastral, land administration system and National SDI initiatives. This will also enable a worldwide comparison of cadastral systems, forming the basis for best practice and a tool to improve national cadastral systems.

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.

ItemVirtual Australia: developing an enabling platform to improve opportunities in the spatial information industry( 2006)The role that the development of Spatial Data Infrastructure initiatives is playing within the modern world is changing. Initially SDIs were implemented as a mechanism to facilitate access and sharing of spatial data hosted in distributed GISs. Users however now require precise spatial information in real time about real world objects and the ability to develop and implement cross-jurisdictional and inter-agency solutions to priorities such as emergency management, natural resource management, water rights and animal, pest and disease control. In order to achieve this, the concept of an SDI is moving to a new business paradigm, where SDI is emerging as a ‘virtual jurisdiction’ or ‘virtual enterprise’ to promote the partnership of spatial information organisations (public/private) to provide access to a wider scope of data and services, of size and complexity that is beyond their individual capacity. The development of such an SDI requires an enabling platform to support the chaining of services across participating organisations. This paper outlines the outcomes of research on the development of such an enabling platform within the context of a Virtual Australia.
