    National land information infrastructure through a collaborative framework
    Marwick, Brian ; RAJABIFARD, ABBAS ; Kalantari, Mohsen ; WILLIAMSON, IAN (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.

    Development of an interoperable tool to facilitate spatial data integration in the context of SDI
    MOHAMMADI, HOSSEIN ; RAJABIFARD, ABBAS ; Williamson, Ian P. (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.

    Critical issues in global geographic information management - with a detailed focused on data integration and interoperability of systems and data
    RAJABIFARD, ABBAS ( 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.

    Geospatial strategic planning for Isfahan municipality
    Sadeghi, Morteza ; Panah, Homayoon Yazdan ; Hosseini, Ali ; Sabagh, Mahmood ; RAJABIFARD, ABBAS (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.
