Due to the exponential growth of spatial information, effective management and curation of geospatial data has become a central concern for GIS libraries. Although geospatial data are often generated based on a set of well-established standards and protocols, best management practices in geospatial data services are still limited. In this paper, the authors review the common challenges of geospatial data management and curation, which include the application of big data, the emergence of Web GIS, and the advancement of cyberinfrastructures. A spatial education project is used as an example to discuss potential best management practices to address these challenges. It is demonstrated that librarians need to be involved at the early stage of a research project and work closely with researchers at all stages of the data life cycle for effective data management. With early involvement of a GIS librarian in the full project development process, all three challenges can be addressed by using best management practices in organizing, managing, publishing, distributing, and preserving the geospatial data.  相似文献

The aim of this paper is to explore whether in today's changing landscape libraries institutional repositories are used, in order to develop collections of locally produced geospatial data. Furthermore, this study will explore the use of policies in developing geospatial collections in order to reveal whether this tool is necessary for librarians who deal with geospatial collections. Finally, it will also detect the role of cooperation in respect to the development of geospatial collections.This research is addressed to librarians working on geospatial collections so as to ascertain their perceptions since they are considered to be the professionals leading changes. The results demonstrate that Map/GIS libraries, along with analog geospatial collections, tend to develop collections from the data their academic community produces. Librarians seem to be convinced that the formulation of policies, the open access to the data, and the establishment of cooperation among stakeholders will be the critical points to accomplish this goal.  相似文献

In this article, we provide an overview of both the social and technical composition of the Open Geoportal (OGP) Federation: an open source, collaborative framework designed to support the various components of spatial data infrastructure and geospatial data repositories. The social components include best-practices, governance models, and working groups, as wells as the OGP wiki, blogs, elists, summits, and virtual meetings. The technical components include the Open Geoportal, Open Geoportal Harvester, and Open Geoportal Metadata Toolkit. We also include benefits and business drivers to adopting this new interoperable, collaborative model.  相似文献

Geospatial data play an increasingly important role in natural resources management, conservation, and science-based projects. The management and effective use of spatial data becomes significantly more complex when the efforts involve a myriad of landscape-scale projects combined with a multiorganizational collaboration. There is sparse literature to guide users on this daunting subject; therefore, we present a framework of considerations for working with geospatial data that will provide direction to data stewards, scientists, collaborators, and managers for developing geospatial management plans. The concepts we present apply to a variety of geospatial programs or projects, which we describe as a “scalable framework” of processes for integrating geospatial efforts with management, science, and conservation initiatives. Our framework includes five tenets of geospatial data management: (1) the importance of investing in data management and standardization, (2) the scalability of content/efforts addressed in geospatial management plans, (3) the lifecycle of a geospatial effort, (4) a framework for the integration of geographic information systems (GIS) in a landscape-scale conservation or management program, and (5) the major geospatial considerations prior to data acquisition. We conclude with a discussion of future considerations and challenges.  相似文献

Abstract

Geographic Information Systems (GIS) as part of the academic library is central on the campus and succeeds with collaboration—in the library, across campus, in the community and region, throughout the state, and at the national level. The integrated components of GIS—hardware, software, data, people, and methods—provide a framework for collaboration. Initiated in 2001, the Geographic Information Systems & Maps Program at the University of Arkansas (UA) Libraries resulted from and developed through collaborative opportunities. The program, which is primarily web based, incorporates locally developed yet nationally recognized resources including Starting the Hunt—a guide to geospatial data on the Web—and GeoStor—a statewide, comprehensive and seamless geospatial data warehouse and delivery system. A model incorporating spheres of collaboration describes the nature and benefits of collaboration at the five different levels, as experienced in the UA Libraries. The model can guide other libraries proactively seeking opportunities of collaboration, in order to develop resources and services for a successful GIS program.  相似文献

As a growing number of disciplines adopt geospatial technologies in their research, the need for access to geospatial data, in a variety of formats, has grown dramatically. For librarians to meet this demand, we also need to provide preservation, curation, metadata, and discovery services. GeoHydra, our open source toolkit and set of practices, provides these services for Stanford's libraries. We incorporate a variety of geospatial content types from raster imagery to scientific vector data to georeferenced scanned maps, and provide a data model for repositories. We demonstrate the potential of a new architecture and practice for librarianship for geospatial data using the Hydra framework. The digitization and georeferencing of historic map collections, streamlining the acquisition and cataloging of vendor-supplied data, shared cataloging of geographic resources, and citation of geospatial research data are all examples of use cases that GeoHydra serves. Our metadata creation and management strategies implement the ISO (International Standards Organization) suite of geographic standards, and a specialized metadata schema for discovery. We developed XSLT transformations, auto-generation of core elements, unique URIs for place names, and cross-institutional data sharing. With these metadata we built a novel geoportal, EarthWorks, to provide end-user discovery for geospatial data layers using GeoBlacklight technology.  相似文献

The Ontario Council of University Libraries (OCUL) is a consortium of the twenty-one university libraries in Ontario, Canada. Since 1967, OCUL member institutions have worked together to share costs and workload through collective purchasing and licensing of information resources and more recently through the establishment of a shared digital infrastructure known as Scholars Portal. Under the auspices of OCUL, Ontario's university map librarians formed the OCUL Map Group in 1973 to seek opportunities to communicate and collaborate to improve the collections and services they offer their users. The opportunities provided by collaboration have ensured a greater capacity to manage evolving collections of geospatial data. The group has served as a community of practice, which has provided educational opportunities and facilitated collaborative problem solving through a listserv, conference calls, and face-to-face meetings. This collegial environment has also led to the completion of a number of projects, which have resulted in the creation of new technical infrastructures and strategies for sharing the workload of data management tasks. This paper discusses the role of collaboration in OCUL projects and offers some suggestions for others considering embarking on collaborations of their own.  相似文献

Abstract

Geospatial information access continues to be central to the mission of geography and map libraries. Providing or facilitating access has been, and continues to be, a dynamic process in light of both technological change and policy challenges. While technological changes in providing access have gathered much attention in the literature, substantive discussions regarding policies and practices preventing or assisting information access have been lacking. Even more troubling is the fact that archiving digital geospatial information receives even less attention. This first paper reviews developments and trends with regard to digital geospatial libraries, as this concept has become the primary metaphor by which access is measured. The second paper will focus on international trends related to the effect of policy and practice in terms of promoting the sharing and use of geospatial information needed to bridge gaps in access. These comparative policy and practice perspectives are also needed in order to point to the true promise held by new technologies for sharing, exemplified by digital libraries designed for geospatial information.  相似文献

Programs for geospatial support at academic libraries have evolved over the past decade in response to changing campus needs and developing technologies. Geospatial applications have matured tremendously in this time, emerging from specialty tools to become broadly used across numerous disciplines. At many universities, the library has served as a central resource allowing students and faculty across academic departments access to GIS resources. Today, as many academic libraries evaluate their spaces and services, GIS and data services are central in discussions on how to further engage with patrons and meet increasingly diverse researcher needs. As library programs evolve to support increasingly technical data and GIS needs, many universities are faced with similar challenges and opportunities. To explore these themes, data and GIS services librarians and GIS specialists from five universities—the University of North Carolina at Chapel Hill, Texas A&M, New York University, North Carolina State University, and California Polytechnic State University—with different models of library geospatial and data support, describe their programs to help identify common services, as well as unique challenges, opportunities, and future plans.  相似文献

ABSTRACT

Maps and geospatial data are critical in disaster response situations. Accurate and updated maps direct first responders to areas of most need, reroute supply lines according to the post-disaster landscape, and help identify remote communities. Unfortunately, accurate and detailed geospatial data is not readily available for many parts of the world. Crowdsourced mapping programs such as Humanitarian OpenStreetMap (HOT) and Tomnod rely on volunteers to create this essential data, with a focus on the world's most vulnerable places. Groups of volunteers contribute to HOT and Tomnod in events called mapathons. This case study at Indiana University Bloomington's Herman B Wells Library asserts that the library is a natural home for humanitarian mapathons, as participants actively engage with spatial and data literacy concepts as they become spatial data creators. Through library mapathons, participants gain spatial and data literacy skills, engage with a global community, connect with other parts of the world, and are exposed to library resources. Hosting a mapathon requires very few specialized skills or knowledge, and has broad appeal. While Indiana University, Bloomington serves about 40,000 students, this case study provides tips and best practices for hosting humanitarian mapathons at libraries of any size.  相似文献

Abstract

Internet access and use of georeferenced public health information for GIS application will be an important and exciting development for the nation's Department of Health and Human Services and other health agencies in this new millennium. Technological progress towards public health geospatial data integration, analysis, and visualization of space-time events using the Web portends eventual robust use of GIS by public health and other sectors of the economy. Increasing Web resources from distributed spatial data portals and global geospatial libraries, and a growing suite of Web integration tools, will provide new opportunities to advance disease surveillance, control and prevention, and insure public access and community empowerment in public health decision making. Emerging supercomputing, data mining, and compression and transmission technologies will play increasingly critical roles in national emergency, catastrophic planning and response, and risk management. Web-enabled public health GIS will be guided by Federal Geographic Data Committee spatial metadata, OpenGIS Web interoperability, and GML/XML geospatial Web content standards. Public health will become a responsive and integral part of rhe National Spatial Data Infrastructure.  相似文献

ABSTRACT

Librarians at universities continue to seek new ways to engage and partner with researchers in order to enhance and enrich the way that they work. This article looks at some of the ways that libraries have been doing this in recent years, what has worked, and what needs to be done to continue to develop these important partnerships. These recommendations will be based on the experiences of Monash University Library, in particular its recent implementation of Figshare for Institutions. The article includes discussion of such topics where libraries have sought partnerships with researchers, such as Open Access, research data management, and capability building, and will focus on the importance of working with researchers to understand their needs.  相似文献

ABSTRACT

For many decades, the Department of Energy (DOE) has been an international leader in basic scientific and engineering research that utilizes geospatial science to advance the state of knowledge in disciplines impacting national security, energy sustainability, environmental stewardship, and associated basic research. However, the realized benefits from cross-cutting geospatial science contributions have fallen short of what they could have been with greater collaboration across the DOE complex, stronger emphasis on core geographic information science (GIScience) research and development to support advanced applications, increased strategic institutional support (e.g., for management of legacy data), and additional education and outreach concerning how geospatial science can benefit DOE programs and operations. We propose a vision for DOE's geospatial science based on expanded collaboration to address major national problems, additional advanced GIScience research and development, and a long-term strategy to better manage DOE's geospatial science resources (personnel, facilities, shared data, etc.).  相似文献

There is an increasing demand for spatial data within the social sciences as such data promise to contribute to a better understanding of how the concrete living environment influences individuals’ attitudes and behaviors. Spatial data can complement data from surveys; however, as of yet there is no spatial data infrastructure for the social sciences in Germany that facilitates merging of spatial data with survey data. This article explores avenues for creating such a spatial data infrastructure (SDI) for the social sciences in Germany. We examine the role that librarians, archivists, and curators can play in offering spatial data infrastructure services for social scientists, and show the scope and nature of necessary tasks in areas such as harmonization, archiving, dissemination, and user support. As the case of Germany is similar to that of other European countries, we expect our results to be helpful in the creation of SDIs in other countries as well. This article suggests technical and organizational measures for merging survey data and spatial data in compliance with German privacy legislation. Measures for storage and dissemination of enriched survey data, for example by providing restricted access to the data in a secured environment, also are explored.  相似文献

As technology and the stewardship of research data continue to improve, academic libraries have made progress in establishing themselves as hubs and leaders for research data services on campus. They have been called on to assure cross-campus collaboration and support to develop a united service to meet their community's needs. However, evidence as to how libraries play a crucial role in leadership, whether other stakeholders' involvement makes a difference, and if so, how that involvement makes a difference is not well-documented. The findings of this study add empirical evidence in supporting the value of library's leadership and stakeholder engagement in developing research data policy and services. The secondary analysis of the survey data found that libraries tend to offer more extensive services when they take primary responsibility for developing the policy and service. It also found that the more internal stakeholders involved in developing the policy and service, the higher level of service maturity the libraries offer. Partnership with external stakeholders leads to more comprehensive and deeper services.  相似文献
