With this objective in mind, countries throughout the world are developing SDIs to manage and utilize 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 15 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 clearing houses. 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.

Assessing the worldwide developments of national spatial data clearinghouses / Joep Crompvoets in International journal of geographical information science IJGIS, vol 18 n° 7 (november 2004)  

Public [article]  inInternational journal of geographical information science IJGIS > vol 18 n° 7 (november 2004) . - pp 665 - 689 Titre : Assessing the worldwide developments of national spatial data clearinghouses Type de document : Article/Communication Auteurs : Joep Crompvoets, Auteur ; Arnold K. Bregt, Auteur ; Abbas Rajabifard, Auteur ; Ian Williamson, Auteur Année de publication : 2004 Article en page(s) : pp 665 - 689 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Infrastructure de données [Termes IGN] catalogue de données localisées [Termes IGN] infrastructure mondiale des données localisées [Termes IGN] INSPIRE [Termes IGN] métadonnées [Termes IGN] serveur de métadonnées [Termes IGN] toile d'araignée mondiale Résumé : (Auteur) Many countries have spent considerable resources over the past few years debating optimal national spatial data infrastructures. One of the (main) elements of these infrastructures is the national spatial data clearinghouse, which facilitates access to required spatial data and provides complementary services. With this in mind, in April 2000, 2001, 2002 and December 2000, 2001, 2002, a web survey was carried out to assess systematically the developments of these national clearinghouses worldwide. Regarding the development in the number of implementations, it can be considered a worldwide success. However, of concern are the declining trends in use, management and content. One of the main reasons for these negative trends could be the dissatisfaction of the spatial data community with the functional capability of current clearinghouses. The functional capabilities of clearinghouses should likely be changed from a data-oriented to a user and application-oriented focus. This is in accord with the objectives of the second generation of spatial data infrastructures. The main factors, therefore, that will have positive impacts on developments in this field are the inclusion of web services, stability of funding and creation of user-friendly interfaces.

Automating the administration boundary design process using hierarchical spatial reasoning theory and geographical information system / S. Eagleson in International journal of geographical information science IJGIS, vol 17 n° 2 (march 2003)

Currently, the majority of spatial boundaries are designed in an uncoordinated manner with individual organizations generating individual boundaries to meet individual needs. As a result, current technologies for analysing geospatial information, such as geographical information systems (GISs), are not reaching their full potential. In response to the problem of uncoordinated boundaries, the authors present an algorithm for the hierarchical structuring of administrative boundaries. This algorithm applies hierarchical spatial reasoning (HSR) theory to the automated structuring of polygons. In turn, these structured boundary systems facilitate accurate data integration and analysis whilst meeting the spatial requirements of selected agencies. The algorithm is presented in two parts. The first part outlines previous research undertaken by the authors into the delineation of administrative boundaries in metropolitan regions. The second part outlines the distinctly different constraints required for administrativeboundary design in rural areas. The development of the algorithm has taken place in a GIS environment utilizing Avenue, an objectorientated programming language that operates under ArcView, the desktop software developed and distributed by ESRI.

Developing a common spatial data infrastructure between state and local government: an Australian case study / S. Jacoby in International journal of geographical information science IJGIS, vol 16 n° 4 (june 2002)  

Public [article]  inInternational journal of geographical information science IJGIS > vol 16 n° 4 (june 2002) . - pp 305 - 322 Titre : Developing a common spatial data infrastructure between state and local government: an Australian case study Type de document : Article/Communication Auteurs : S. Jacoby, Auteur ; L. Ting, Auteur ; Ian Williamson, Auteur ; J. Smith, Auteur Année de publication : 2002 Article en page(s) : pp 305 - 322 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Infrastructure de données [Termes IGN] Australie [Termes IGN] collectivité territoriale [Termes IGN] échange de données informatisé [Termes IGN] infrastructure nationale des données localisées [Termes IGN] intégrité des données Résumé : (Auteur) Over the last decade a number of countries and states have successfully established complete spatial data infrastructures (SDIs) incorporating core digital map bases such as the cadastre or land parcel layer, topography, hydrology, road networks and administrative boundaries. These have usually been based on the amalgamation of national or state mapping and cadastral or land registration systems. At the same time many cities or Local Governments world-wide have established their own SDIs although they are more commonly referred to as geographical information systems. However in most cases the relationship between the Local Government and the National or State systems is at best poor. The result is that in many cases Local Government does not use the state SDI. This presents many difficulties in establishing state or national data sets, particularly where Local Government is responsible for controlling or maintaining the integrity of specific land related data in the state SDI. This paper describes the successful establishment of a partnership between 78 Local Government authorities and a State Government in Australia. This successful partnership has resulted in the State providing and updating the basic SDI for Local Government and Local Government in turn providing land parcel and property data to the State Government. This has resulted in significant improvements being made to the core map bases in the State SDI (such as the increased integrity of the state street address file), a marked reduction in duplicative mapbase maintenance activity (particularly by Local Government) and increased adoption of GIS technologies by Local Government with the beginnings of considerable flow-on benefits to the community being observed. The authors believe that this is a useful model which facilitates the SDI concept becoming a reality and which has generic application in many countries world-wide.
