Geospatial data stewardship fosters user-driven collection, management, access, reuse, and preservation of location-based data. Academic and research libraries are poised to be at the center of geospatial data stewardship, working with partners to develop a sustainable, geospatial data stewardship hub. This article argues for the essential role of libraries in leading collaborative partnerships to develop a user-driven, spatial data infrastructure that includes people, policies, standards, community perspectives, and operational workflows. The emerging model of partnership-based spatial data infrastructure described at the Washington University Libraries demonstrates working methods in practice.  相似文献

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

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

The Terra Populus project (TerraPop) addresses a variety of data management, curation, and preservation challenges with respect to spatiotemporal population and environmental data. In this article, we describe our approaches to these challenges, with a particular focus on geospatial data workflows and associated provenance metadata. The goal of TerraPop is to enable research, learning, and policy analysis by providing integrated spatiotemporal data describing people and their environment. To do so, TerraPop is assembling a globe-spanning and temporally extensive collection of high-quality population and environmental data, ensuring good documentation, and developing a Web-based data access system that enables users to assemble customized integrated data sets drawing on a variety of data sources and formats. We describe TerraPop's collection strategies, detail the geospatial workflows involved in preparing data for ingest into the project database and those used to transform data across formats for dissemination, and discuss the system used to capture and manage provenance metadata throughout the project. A key aspect of the project is the development of global current and historical administrative unit boundaries that can be linked to census data. These boundaries serve as the linchpin of TerraPop's data integration strategy, and constitute an important data set in their own right.  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

As geospatial missions age, one of the challenges for the usability of data is the availability of relevant and updated metadata with sufficient documentation that can be used by future generations of users to gain knowledge from the original data. Given that remote sensing data undergo many intermediate processing steps, for example, an understanding of the exact algorithms employed and the quality of that data produced could be key considerations for these users. As interest in global climate data is increasing, documentation about older data, their origins, and their provenance are valuable to first-time users attempting to perform historical climate research or comparative analysis of global change. Incomplete or missing documentation could be what stands in the way of a new researcher attempting to use the data. Therefore, preservation of documentation and related metadata is sometimes just as critical as the preservation of the original observational data. The Goddard Earth Sciences–Data and Information Service Center (GES DISC), a NASA Earth science Distributed Active Archive Center (DAAC) that falls under the management structure of the Earth Science Data and Information System (ESDIS), is actively pursuing the preservation of all necessary artifacts needed by future users.

In this article, we will detail the data custodial planning and the data lifecycle process developed for content preservation, and our implementation of a Preservation System to safeguard documents and associated artifacts from legacy (older) missions, as well as detail lessons learned regarding access rights and confidentiality of information issues. We also elaborate on key points that made our preservation effort successful; the primary points being drafting of a governing baseline for historical data preservation from satellite missions and using the historical baseline as a guide to content filtering of what documents to preserve. The Preservation System currently archives documentation content for High Resolution Dynamics Limb Sounder (HIRDLS), Upper Atmosphere Research Satellite (UARS), Total Ozone Mapping Spectrometer (TOMS) mission data, and the 1960s era Nimbus mission. Documentation from other missions like the Tropical Rainfall Measuring Mission (TRMM), the Ozone Monitoring Instrument (OMI), and the Atmospheric Infra-Red Sounder (AIRS) are also slated to be added to this repository, as well as other mission datasets to be preserved at the GES DISC.  相似文献

The United States’ National Oceanic and Atmospheric Administration (NOAA) operates over one hundred observing systems and numerical models providing information and forecasts about the planetary environment from the bottom of the ocean to the surface of the Sun. Collected NOAA data constitute an irreplaceable resource that must be well-documented, discoverable, accessible, and preserved for future use. Good data management should therefore be part of NOAA's core business practices, and employees and leadership should be aware of their roles and responsibilities in this arena. NOAA has developed an Environmental Data Management (EDM) Framework document that discusses Principles, Governance, Resources, Standards, Architecture, Assessment, and the Data Lifecycle, and which also enumerates specific recommendations. The NOAA EDM Committee has issued Directives pertaining to data management planning, archiving, data access, metadata, and other topics. A Data Catalog has been established, and a project to assign persistent, citable identifiers to archival data is well underway. Numerous groups at NOAA are performing technical work related to data access, usability, and preservation.

The purpose of this article is to describe these documents and activities in order to share our experiences and to provide guidance and encouragement for improved data management practices and processes at other organizations.  相似文献

The complexity and size of geospatial data can constrain the capabilities of service providers and create risks to the long-term preservation and archiving of valuable information assets. While services-oriented architectures such as the Earth Data Analysis Center's Geographic Storage, Transformation and Retrieval Engine (GSToRE) facilitate increased use and impact of geospatial data by mitigating these complexities by development of dynamic applications and interfaces, such services can often be primarily focused on the maintenance and delivery of only the most current versions of geospatial data that may nonetheless possess significant historical, cultural, or scientific value. Actions and documentation required to assure long-term preservation may not be supported by existing business models or may be otherwise compromised. However, general purpose archives offer a preservation capability that is complementary to the value created by dynamic service providers. We present an overview of the features of GSToRE, and the DSpace repository platform and describe the requirements of a methodology for the harvest, quality assurance, and ingest of geospatial data into an institutional repository as a complement to the dynamic data access and visualization services provided by GSToRE and systems like it.  相似文献

The University of Florida GeoPlan Center has been organizing, standardizing, and distributing geospatial data since 1998 through the Florida Geographic Data Library (FGDL), a collection of Florida geospatial data from various agencies, as well as data developed in-house. With funding from the Florida Department of Transportation (FDOT), FGDL serves as a public distribution mechanism for hundreds of Florida geospatial data layers. Since 2004, FGDL layers have formed the data foundation for FDOT's interagency application known as efficient transportation decision making (ETDM), which facilitates the review and permitting process for proposed transportation projects. Data layers are standardized and inspected to ensure that the data are adequate for use in analysis and decision making. To efficiently manage the geospatial data and workflows, a quality assurance/quality control (QAQC) process and relational database schema was developed to track the standardization procedures, lineage, versioning, and archiving of the data layers. This article details the history of the Florida Geographic Data Library, challenges of managing a large geospatial data repository, development of a QAQC process and database schema, and lessons learned.  相似文献

This article presents a multifarious examination of natural resources and environmental scientists' adventures navigating the policy change toward open access and cultural shift in data management, sharing, and reuse. Situated in the institutional context of Virginia Tech, a focus group and multiple individual interviews were conducted exploring the domain scientists' all-around experiences, performances, and perspectives on their collection, adoption, integration, preservation, and management of data. The results reveal the scientists' struggles, concerns, and barriers encountered, as well as their shared values, beliefs, passions, and aspirations when working with data. Based on these findings, this study provides suggestions on data modeling and knowledge representation strategies to support the long-term viability, stewardship, accessibility, and sustainability of scientific data. It also discusses the art of curation as creative scholarship and new opportunities for data librarians and information professionals to mobilize the data revolution.  相似文献

Although federally supported geospatial data clearinghouses have appeared on the Internet, there exist few resources allowing for a coordinated collection of publicly available geospatial data over large areas. The completion of a national survey of potential producers of geospatial data provides users with a new way of learning about relevant, publicly accessible data when they embark on projects with a spatial component. This article presents a progress report on the National Survey of Geospatial Framework Data. The survey's methodology is described, allowing for readers to anticipate both the nature and extent of the survey results. Also described are the means by which the final results will be released. The survey results will serve as a major national source of information regarding where public geospatial data can be obtained at all levels of government. This article is intended to encourage access to the survey results so the results reach an appropriate audience while still timely and relevant. The survey will serve as a new source of information having implications for access to geospatial data nationwide. Published by Elsevier Science Ltd  相似文献
