Description : In describing the emergence of the spatial data infrastructure (SDI) phenomenon, this book covers the diffusion and evolution of SDIs around the world, and indicates the countries in which SDIs are far along, and those in which more work is needed. The implementation of SDIs from a practical perspective and a method of institution building for regional, continental, and global SDIs is outlined. This guide offers recommendations about how SDI stakeholders around the world can leverage the work already done and maintain the momentum that is currently driving the global SDI phenomenon.
Description : Expert perspectives on SDI theory and practice The spatial data infrastructure (SDI) concept continues to evolve and become an increasingly important element of the infrastructure that supports economic development, environmental management, and social stability. Because of its dynamic and complex nature, however, it remains a fuzzy concept to many, and depending on their needs and circumstances, practitioners, researchers, and governments adopt different views of it. Developing Spatial Data Infrastructures: from Concept to Reality makes a timely contribution to the theory and practice of SDIs and breaks new ground in improving understanding of their relevance and value. It provides expert overviews of policies, concepts, standards, and practices associated with the design, implementation, and operation of SDIs. It introduces the concept of an SDI Hierarchy based on Hierarchical Spatial Reasoning, sets out the similarities and differences between SDIs operating within and between different jurisdictions, and identifies factors key to the success of SDI initiatives. Built on key contributions to the International Symposium on Spatial Data Infrastructure held in Melbourne in November 2001, this book is the first of its kind to provide address both the theoretical and practical aspects of developing appropriate SDIs. It offers unique, detailed discussions on the challenges and direction of future SDI development and thus provides an outstanding resource for those involved in building and maintaining SDIs and for GIS professionals and students.
Description : Metadata play a fundamental role in both DLs and SDIs. Commonly defined as "structured data about data" or "data which describe attributes of a resource" or, more simply, "information about data", it is an essential requirement for locating and evaluating available data. Therefore, this book focuses on the study of different metadata aspects, which contribute to a more efficient use of DLs and SDIs. The three main issues addressed are: the management of nested collections of resources, the interoperability between metadata schemas, and the integration of information retrieval techniques to the discovery services of geographic data catalogs (contributing in this way to avoid metadata content heterogeneity).
Description : This book draws on author’s wealth of knowledge working on numerous projects across many countries. It provides a clear overview of the development of the SDI concept and SDI worldwide implementation and brings a logical chronological approach to the linkage of GIS technology with SDI enabling data. The theory and practice approach help understand that SDI development and implementation is very much a social process of learning by doing. The author masterfully selects main historical developments and updates them with an analytical perspective promoting informed and responsible use of geographic information and geospatial technologies for the benefit of society from local to global scales. Features Subject matter spans thirty years of the development of GIS and SDI. Brings a social science perspective into GIS and SDI debates that have been largely dominated by technical considerations. Based on a world-wide perspective as a result of the author's experience and research in the USA, Australia, Canada, Brazil, Peru, China, India, Korea, Malaysia, and Japan as well as most European countries. Draws upon professional and academic experience relating to pioneering UK and European GIS research initiatives. Includes updated historical material with an analytical perspective explaining what was done right, and what didn't work.
Description : Spatial data, also known as geospatial data or geographic information, identifies the geographic location of natural and constructed features and boundaries on Earth, and has become increasingly important in various administrative practices. In order to facilitate access, use, and sharing of spatial data among organizations, information is brought together in clustered initiatives known as Spatial Data Infrastructures (SDIs). In Spatial Data Infrastructures at Work, Ezra Dessers introduces spatial enablement as a key concept to describe the realisation of SDI objectives in the context of individual public sector processes. Drawing on four years of research, Dessers argues that it has become essential, even unavoidable, to manage and (re)design interorganizational process chains in order to further advance the role of SDIs as an enabling platform for a spatially enabled society. Detailed case studies illustrate that the process he describes is the setting in which one can see the SDI at work. This book is must-read material for academics, practitioners, and policymakers dealing with SDI and spatial enablement. By extension, the book will also be of great interest to anyone confronted with societal issues that call for an integrated approach, implying in-depth cooperation between multiple organizations.
Description : Geospatial data, information, and technologies are becoming more important and more common tools throughout the world because of their capacity to improve government and private-sector decisionmaking in such areas as transportation, environment, natural resources, agriculture, telecommunications, mapping, health, emergency services, research, and national security. This report presents an analysis of international collaboration for the Global Spatial Data Infrastructure (GSDI).
Description : Spatial Data Infrastructure plays significant role for the development of a nation. It contributes to sustainable development of a country through facilitating spatial data sharing and utilization among all levels of stakeholders. Thus, conducting SDI assessment is essential to guide its development, to monitor and improve its quality and to provide evidence of accountability for all stakeholders. Knowledge of the development status of SDI of a country is crucial to increase the accountability and development of spatial data information. In Ethiopia, there are many governmental organizations that produce spatial data to fulfill the need of geo-information in various sectors. However, the overall development status of the SDI in Ethiopia is not well known. The objective of this study is to assess the development and milestones of Ethiopian National Spatial Data Infrastructure (ENSDI). The assessment of the status of ENSDI is done by using the four multi-view assessment framework approaches; SDI-readiness, Modified state of play, Clearinghouse suitability index and Organizational approaches. The assessment of the milestones in the development of ENSDI is done using document analysis and interview with key stakeholders. Both assessment of status and milestones of the development of ENSDI involve questionnaire survey, interview and document analysis as data collection tool. Data analysis was done on the four assessment approach. The result of multi-view assessment shows that, shortage of digital data, lack of open-source data, lack of SDI awareness, and unavailability of environmental dataset policy are the major weak aspects of the ENSDI. Moreover, the technology components and data quality standards of the NSDI are very low. This is mainly due to lack of awareness among stakeholders on ESDI, low technological development, human capital, SDI culture, shortage of digital data and poor coordination of various institution in data production and exchange. On the other hand, clear mission and vision, collaboration with International donors are strong aspects of the NSDI. The major milestones that initiated NSDI development in Ethiopia are the establishment of GIS education, ENRAMED database, National Clearinghouse, GIS Society of Ethiopia and Ethiopian Geospatial Metadata Clearinghouse Node. The research identifies awareness creation for SDI, increasing ICT technology in the country, developing SDI curriculum in higher education, creation of open source data, converting analogue data to digital data, increasing cooperation of various institution in data sharing and provision, and developing data quality control procedures as the major areas of interest for NSDI secretariat to do.
Description : The National Spatial Data Infrastructure (NSDI) was envisioned as a way of enhancing the accessibility, communication, and use of geospatial data to support a wide variety of decisions at all levels of society. The goals of the NSDI are to reduce redundancy in geospatial data creation and maintenance, reduce the costs of geospatial data creation and maintenance, improve access to geospatial data, and improve the accuracy of geospatial data used by the broader community. At the core of the NSDI is the concept of partnerships, or collaborations, between different agencies, corporations, institutions, and levels of government. In a previous report, the Mapping Science Committee (MSC) defined a partnership as "...a joint activity of federal and state agencies, involving one or more agencies as joint principals focusing on geographic information." The concept of partnerships was built on the foundation of shared responsibilities, shared costs, shared benefits, and shared control. Partnerships are designed to share the costs of creation and maintenance of geospatial data, seeking to avoid unnecessary duplication, and to make it possible for data collected by one agency at a high level of spatial detail to be used by another agency in more generalized form. Over the past seven years, a series of funding programs administered by the Federal Geographic Data Committee (FGDC) has stimulated the creation of such partnerships, and thereby promoted the objectives of the NSDI, by raising awareness of the need for a coordinated national approach to geospatial data creation, maintenance, and use. They include the NSDI Cooperative Agreements Program, the Framework Demonstration Projects Program, the Community Demonstration Projects, and the Community-Federal Information Partnerships proposal. This report assesses the success of the FGDC partnership programs that have been established between the federal government and state and local government, industry, and academic communities in promoting the objectives of the National Spatial Data Infrastructure.
