ItemDevelopment of an interoperable tool to facilitate spatial data integration in the context of SDI(Taylor & Francis, 2010)The integration of multisource heterogeneous spatial data is one of the major challenges for many spatial data users. To facilitate multisource spatial data integration, many initiatives including federated databases, feature manipulation engines (FMEs), ontology-driven data integration and spatial mediators have been proposed. The major aim of these initiatives is to harmonize data sets and establish interoperability between different data sources. On the contrary, spatial data integration and interoperability is not a pure technical exercise, and there are other nontechnical issues including institutional, policy, legal and social issues involved. Spatial Data Infrastructure (SDI) framework aims to better address the technical and nontechnical issues and facilitate data integration. The SDIs aim to provide a holistic platform for users to interact with spatial data through technical and nontechnical tools. This article aims to discuss the complexity of the challenges associated with data integration and propose a tool that facilitates data harmonization through the assessment of multisource spatial data sets against many measures. The measures represent harmonization criteria and are defined based on the requirement of the respective jurisdiction. Information on technical and nontechnical characteristics of spatial data sets is extracted to form metadata and actual data. Then the tool evaluates the characteristics against measures and identifies the items of inconsistency. The tool also proposes available manipulation tools or guidelines to overcome inconsistencies among data sets. The tool can assist practitioners and organizations to avoid the time-consuming and costly process of validating data sets for effective data integration.

ItemCritical issues in global geographic information management - with a detailed focused on data integration and interoperability of systems and data( 2010)The GSDI Association continues its support for the United Nations for taking the initiative on this critical global geographic information issue; and is willing to contribute to new arrangements to improve global geographic information management. The role of the GSDI Association, in essence, is to facilitate better global outcomes through utilisation of geographic information and spatial data infrastructures (SDIs). This role directly complements the proposal to establish a United Nations Committee on Global Geographic Information Management (UNCGGIM). The GSDI Association's view of the changes now taking place in the geographic information world and these changes exemplify convergence of technologies and disciplines. These changes need to be influenced where appropriate, and leveraged, by the global geographic information community, particularly by the United Nations. This paper presents some views related to the “critical issues in global geographic information management” and in particular a response to the following issues: - Governance: is global governance relevant and necessary? - Interoperability of systems and data - Data integration and layering, and - Capacity building and technology transfer In responding to these issues, the paper however provides a more detailed discussions on “interoperability of systems and data” and “data integration” in particular the technical and non-technical issues and heterogeneity associated with multi-sourced spatial data integration in the context of SDI.

ItemGeospatial strategic planning for Isfahan municipality(Leuven University Press, 2010)Nowadays, globalization and rapid changes in developing countries affect the behavior and culture of people. Adapting to these changes is the vital means to remain in the competition of being a developed society. One of the most important changes is the relationship between humans and land which have evolved by way of many parameters such as globalization, urbanization, technological and economic reforms. In order to be able to adapt this changing relationship it is required to enable societies by developing new infrastructures and tools. Strategic planning is a key concept for effective and successful development of these infrastructures and tools which have to be considered by the governments and decision makers. The municipality of Isfahan, a metropolitan city in the central part of the Iran, in 2006 established a strategic plan for spatial data and services infrastructure and its first revision and evaluation has been done in 2009. This paper describing the principals of spatial strategic planning in multi-unit organizations, such as municipalities, the results of establishing this strategic plan in Isfahan municipality is also presented. The geospatial strategic plan in this project had four stages including comparative studies, investigating high level related documents, developing visions and missions and designing GIS strategic plan using SWOT analysis. In this study, major strategies and policies are proposed in the domains of Geospatial Businesses (GB), Geospatial Systems and Services (GSS), Geospatial Data (GD) and Geospatial Information Technology (GIT). In order to achieve the high level performance, different infrastructure components for enabling geospatial businesses, projects for geospatial enabling systems and services, projects for enabling geospatial data acquisition and different projects for enabling geospatial information technology are proposed. Concentrating on spatial data and service infrastructures and capacity building, an evaluation of an ongoing plan has also been done to check the compliance of that with the new changes and conditions. The evaluation illustrates that the plan leads to better realizing spatially enabling Isfahan municipality to deliver better services to its citizens.

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.
