ItemSnapshot of SDI Development in Australia: Models, Partnerships and Lead Agencies Advancing Implementation( 2002)Australia is entering a new era for spatial data infrastructure (SDI) demonstrated by the unification of prime sectors of the spatial information industry and a renewed Government focus on spatial information. A spatial information stock take is required to review progress to date and evaluate current directions. SDI is deemed essential for the provision of services to support modern society's information needs and can be considered in the same manner as other public service infrastructure such as roads and utilities.This paper will evaluate progress since the release of ANZLIC's (1996) model for a SDI for Australia and New Zealand, identify the agencies driving SDI in Australia and will highlight key initiatives contributing to the ASDI development. Selected countries with advanced National Spatial Data Infrastructure (NSDI) programs will also be discussed in relation to developments of the SDI model within Australia. The paper contributes to research conducted by the Centre for Spatial Data Infrastructures and Land Administration at the University of Melbourne on SDI and to a new project being undertaken to develop a methodology to map the complex nature of the institutional arrangements and partnerships that support NSDI with particular focus on the ASDI.

ItemSDI governance bridging the gap between people and geospatial resources( 2009)Organisational arrangements have long been recognised as a critical enabler and fundamental component of Spatial Data Infrastructure (SDI). More recently, the term “governance” has become increasingly used to refer to aspects of institutional frameworks that support SDI. However, given the polysemous nature of the term and the evolving nature of approaches to implementing SDI, it not clear exactly what is meant by the term “SDI governance” and thus the scope, nature and challenges of governance are not well understood. Through an exploration of concepts and model of governance in a variety of contexts, a conceptual model of SDI governance is being developed. An investigation of practical realities of governance in four Australian SDI initiatives has been used to inform the development of this model. This paper provides an overview of the concepts of governance, presents some key findings from the Australian SDI cases studies; and describes an initial conceptual model of governance.

ItemDeveloping a seamless SDI model across the land-sea interface( 2007)A more integrated and holistic approach to management of spatial information relating to coastal and marine environments is needed and this can be facilitated by the creation of a Spatial Data Infrastructure (SDI) on a seamless platform. There is a growing and urgent need to create a seamless SDI model that bridges the gap between the terrestrial and marine environments, creating a spatially enabled land-sea interface to more effectively meet sustainable development objectives. This paper discusses the principles and concepts followed by introduction to issues and challenges that must be overcome in developing an overarching architecture for a seamless SDI that allows access to and interoperability of data from marine, coastal and terrestrial environments.

ItemBuilding the spatial data infrastructure through data sharing: measuring progress within Australian local and state government jurisdictions( 2007)In the past decade efforts to develop spatial data infrastructures (SDIs) have migrated from the initial “top-down” national approaches to “bottom-up” and cross jurisdictional efforts at the sub-national level. Although national SDI developments are fundamental to building the SDI culture and policy, it is sub-national and local SDI development that will deliver the immediate benefits to citizens and the community. In countries which have highly decentralised federations of states such as Australia, United States and Canada, the challenge is how to co-ordinate the literally thousands of often small local government jurisdictions which are important contributors to state and local SDIs. In recent years, a number of co-operative spatial data sharing partnerships between local and state government have emerged in Australia. These partnerships are relatively new initiatives that have been established to facilitate more effective sharing of spatial data between organisations, but also as a mechanism to contribute to SDI development. To maximise the benefits from these partnerships it is essential to understand the factors that contribute to their successful operation and sustainability. This paper investigates these collaborative arrangements and examines the motivations, mechanisms and frameworks for data sharing between local and state governments.

ItemA strategy framework to facilitate spatially enabled Victoria( 2009)Spatial Information is at a critical turning point in its development. More people are using it for a wider range of purposes, including social networking; technology is changing the way we communicate with each other; there are new ways of thinking about ‘location’; and big corporate players are entering the market and are starting to drive standards. At the same time, all levels of government, business and the community face significant challenges in producing and using products and services in environmentally and socially sustainable ways. Spatial information has an integral part to play in developing solutions to these challenges. But this cannot be achieved without a clear strategy and a framework that harnesses everyone’s skills and expertise. Victoria is fast being recognised as a leader in many aspects of State SDI development in Australia and internationally. The Victorian Spatial Council – which is the peak body that provides a coordinated approach to policy and development and management of spatial information – has recently painted the emerging landscape for spatial information in Victoria. Through the Victorian Spatial Information Strategy 2008-2010 it highlights some of the changes occurring in spatial information and technology and the key challenges they pose, and sets the broad themes for facilitating the whole spatial information community’s participation in that landscape. VSIS is a basis for delivering spatially enabled Victoria. At the same time, it considers that spatial information should be seen as part of the wider information resource created by and available to society. It presents a challenging agenda and the strategic framework it sets out lays the foundation for fulfilling the promises that are held out by the developments it describes. This paper aims to present and discuss VSIS, its development process and its role in connecting all levels of government, the private sector, utilities, academia, the professions and a wider community from a spatial data perspective. The paper starts with a discussion on the importance of having a spatial information framework in the context of spatially enabled society and then discusses the central role VSIS plays in facilitating the spatially enabled vision in Victoria. The paper then highlights a range of activities and processes to be undertaken across all disciplines and sectors to facilitate framework development. This includes aspects of design, creation, governance and processes involved in developing an enabling platform, and the overall relations between different challenges to facilitate spatial data activities. The results and lessons learned from the development of the strategy can be used and applied in other jurisdictions, at both national and global levels.

ItemDeveloping a goal-oriented SDI assessment approach using GIDEON-the Dutch SDI implementation strategy-as a case study( 2009)In 2008, the Dutch government approved the GIDEON document as a policy aiming at the implementation of the National Spatial Data Infrastructure (NSDI) in the Netherlands. The execution of GIDEON should take place by pursuing seven implementation strategies which lead to the achievement of the GIDEON goals. GIDEON also expresses the need to monitor the progress of implementing its strategies and realization of its goals. Currently, the work has been started on monitoring the GIDEON implementation strategies. However, there is still a lack of knowledge and methods to monitor GIDEON goals realization. The challenge is to come up with an approach to assess to what extent these goals are achieved. As a response to the challenge of assessing the GIDEON goals, this paper explores the possibility of using the Multi-view SDI assessment framework (Grus et al., 2007). This paper presents and discusses the method that applies the Multi-view SDI assessment framework, its indicators and measurement methods to create a GIDEON assessment approach. The method of creating a GIDEON assessment approach consists of several procedural steps: formulating specific GIDEON objectives, organizing a one-day workshop involving focus group of specific stakeholders responsible for creation and execution of NSDI, asking the workshop participants to select from a long list those indicators that best measure the achievement of each GIDEON goals. The key step of GIDEON approach is a one-day workshop. The workshop participants represented all organizations that cooperated and/or created GIDEON. The workshop consisted of two parts: first part explained the context of a challenge of assessing GIDEON, second part included participants activity to select and come to the consensus on the list of indicators that would best measure GIDEON goals realization. Additionally, the participants were asked to evaluate and express feedback on the usefulness of the method of creating GIDEON assessment approach. The results show that several indicators that relate to specific SDI goals could be selected by a significant number of workshop participants. The indicators that have been selected are not the final ones yet, but provide a guideline and form a base of what has to be measured when assessing GIDEON goals. Involving the representatives of all parties committed to GIDEON into the process of GIDEON assessment approach creation will strengthen its robustness and acceptance. The results of the feedback form filled by each participant show that the presented method is useful or very useful to create GIDEON assessment approach. Additionally, some of the participants provided already their own indicators which are very specific for Dutch SDI monitoring. The method presented in this research, assuming that SDI goals are defined and the organizations that participate in SDI creation are known, can be applied in any other country to develop country-specific and practical SDI assessment approach.

ItemAn Initial Model Of The Computation Viewpoint For A SDI( 2007)The Commission on Spatial Data Standards of the International Cartographic Association (ICA) is working on defining formal models and technical characteristics of Spatial Data Infrastructures (SDI). The Commission has already presented models of the Enterprise and Information Viewpoints from the ISO Reference Model for Open Distributed Processing (RM-ODP) standard (ISO/IEC 10746:1995). The Commission is now taking this further to model the Computation Viewpoint, which describes how the different services of an SDI fit together. The models should be seen as a continuing step towards the overall model of the SDI and its technical characteristics.The Commission has identified six broad groupings of services: Registry, Data, Processing, Portrayal, Application and Management. The interactions between these high-level services have been modelled using the Unified Modeling Language (UML) Component Diagrams. The detailed services have been modelled using UML Class Diagrams (Object Management Group 2005).
