Transcript of "The New Trends for Librarians in Management of Geographic Information"

  1. 1. Ionian University Department of Archive and Library Sciences Laboratory on Digital Libraries and Electronic PublishingThe New Trends for Librarians in Management of Geographic Information Ifigenia Vardakosta Sarantos Kapidakis {ifigenia,sarantos}@ionio.gr 2nd IC-ININFO Budapest, 30 Aug. – 2 Sept., 2012
  2. 2. Session Overview• Purpose of the presentation• Geographic Information (GI)• Geographical Collections (GC)• How Librarians Manage GI• Libraries and Geographical Metadata• Most used tools• What’s new? 2nd IC-ININFO Budapest, 30 Aug - 2 Sept.,201 2
  3. 3. This presentation aims…• To highlight the importance of GI and its proper management• To overview the tools most commonly used for GI management and,• Demonstrate the latest changes and developments in this area according the international literature. 2nd IC-ININFO Budapest, 30 Aug - 2 Sept.,201 3
  4. 4. Geographic Information (GI) “Information about objects or phenomena that are associated with a location relative to the surface of the Earth” (Association of Geography Information)Why GI is important?• Almost all human activities contain a geographic element• The GI processing involves complex and difficult choices which are to a large extent unique (Longley e.a., 2010) 2nd IC-ININFO Budapest, 30 Aug - 2 Sept.,201 4
  5. 5. The main characteristics of GI• there is no uniform data model,• geospatial data vary widely in the amount of information they show,• these data are being stored in relational geodatabases requiring sophisticated storage and archiving schemes,• geospatial imagery datasets are often quite large and metadata may be voluminous as well,• geospatial data may be produced over time,• are subject to versioning because of updated information being made available or to correct past errors in the data (Janee, 2009 ; Erwin & Sweetkind-Singer, 2010) 2nd IC-ININFO Budapest, 30 Aug - 2 Sept.,201 5
  6. 6. Geographic Collection (GC) A Geographic Collection consists materials suchas books, serials, maps, atlases, aerial photos,remote sense images, geospatial data, softwareetc which dealing with the study of the impact ofpeople upon the earth. The GeographicCollection is designed to support instruction,recreational needs, and research in theorganization that library serves. 2nd IC-ININFO Budapest, 30 Aug - 2 Sept.,201 6
  7. 7. Our research so far indicates that…Academic Libraries worldwide:• Collect geographical data in a variety of type, format and subject• Sustain Geographic Collections• Develop GIS services for dealing with their users needs (Vardakosta and Kapidakis, 2011, 2012a,2012b, 2012c) 2nd IC-ININFO Budapest, 30 Aug - 2 Sept.,201 7
  8. 8. The main role of a GIS Librarian…• Acquire data• Extract geographic information• Extract semantic and ontological information• Present in a form that allows easy exploration by users (Turton, e.a., 2007) 2nd IC-ININFO Budapest, 30 Aug - 2 Sept.,201 8
  9. 9. How librarians manage GI1) By contributing in the development of interactive geo-services in their libraries, and2) By using the proper descriptive standards 2nd IC-ININFO Budapest, 30 Aug - 2 Sept.,201 9
  10. 10. 1. Interactive Geo-Services in Libraries Information services for the public usually for aspecific subject e.g. health, environment,archaeology etc. Some of them allow user to enter postcode, placename or address details to retrieve informationand a map displays specific to their locations (Mathys and Kamel Boulos, 2011) 2nd IC-ININFO Budapest, 30 Aug - 2 Sept.,201 10
  11. 11. 1. a. A vision of Britain through time http://www.visionofbritain.org.uk/ 2nd IC-ININFO Budapest, 30 Aug - 2 Sept.,201 11
  12. 12. 1. b. Harvard Geospatial Library http://calvert.hul.harvard.edu:8080/opengeoportal/ 2nd IC-ININFO Budapest, 30 Aug - 2 Sept.,201 12
  13. 13. 2. Geographical Metadata Metadata are data that describe the content, datadefinition and structural representation, extent (bothgeographic and temporal), spatial reference, quality,availability, status and administration of a geographicdataset. (IFLA) Geographical Metadata’s role: •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) (Nogueras-Iso, e.a., 2005) 2nd IC-ININFO Budapest, 30 Aug - 2 Sept.,201 13
  14. 14. Digital Communication Standards• GML (Geography Markup Language). Is an open industry standard that uses XML encoding for the transport and storage of GI including both the geometry and properties of geographic features, such as feature, geometry, coordinate reference system time, dynamic feature, coverage (including geographic images) unit of measure, and map presentation style (Hanson & Heron, 2008,p.133)• Z39.50 is an open, well-established communications protocol for information sharing on wide area networks (ESRI, 2002) 2nd IC-ININFO Budapest, 30 Aug - 2 Sept.,201 14
  15. 15. Metadata Content Standards (1)1) (FGDC-CSDGM) Content Standard for Digital Geospatial Metadata, officially known as FGDC-STD-001-1998 (USA)• with over 334 different elements, 119 of which exist only to contain other elements2) ISO 9115 (2003)• has more than 350 elements3) Australia New Zealand Land Information Council (ANZLIC)Project4) Dublin Core (DC)Since 2003 has been adopted as ISO standard (ISO 15836)5) INSPIRE Directive (2009) 2nd IC-ININFO Budapest, 30 Aug - 2 Sept.,201 15
  16. 16. Gazetteers (1) Digital gazetteers are directories containing triples of Place names (N), geographic footprints (F), and feature types (T) for named geographic places (Hill, 2000)• Some gazetteers provide information about places and features• Some lists of geographic names are available as hierarchical term sets (thesauri) designed for information retreivalExamples: GeoRef Thesaurus (American Geological Institute) Thesaurus of Geographic Names (Getty Museum) Geographic Names Information System (GNIS) Geographic Names Processing System (GNPS) Alexandria Digital Library Gazetteer 2nd IC-ININFO Budapest, 30 Aug - 2 Sept.,201 16
  17. 17. Gazetteers (2)Gazetteers so far are unable to:respond to complex queries spanning across different gazetteers and typingschemas, andthey lack the functionality to handle evolving data of differing quality, e.g.,user generated content (Keßler e.a., 2009) 2nd IC-ININFO Budapest, 30 Aug - 2 Sept.,201 17
  18. 18. AACR2r – RDA - FRBR• AACR2r : facilitates data sharing among disparate systems and frees the cataloger from having to reinvent the rules for each dataset• RDA : has the ability to better describe and embed FGDC data elements and description into the bibliographic and authority records (Hanson & Heron, 2008, p.91)• FRBR : a conceptual model for creating bibliographic records 2nd IC-ININFO Budapest, 30 Aug - 2 Sept.,201 18
  19. 19. Linked Data• Proposed 2006 by Berners-Lee: “data (its web representation) can contains links to data located elsewhere on the Web”.• "Linked Data" refers to data published in accordance with principles designed to facilitate linkages among datasets, element sets, and value vocabularies. Linked Data uses Uniform Resource Identifiers (URIs) as globally unique identifiers for any kind of resource. In Linked Data, URIs may be Internationalized Resource Identifiers (IRIs) – Web addresses that use the extended set of natural-language scripts supported by Unicode. Linked Data is expressed using standards such as Resource Description Framework (RDF) which specifies relationships between things -- relationships that can be used for navigating between, or integrating, information from multiple sources.• Linked Data is sharable, extensible, and easily re-usable. (Stanford Linked Data Workshop, 2011) 2nd IC-ININFO Budapest, 30 Aug - 2 Sept.,201 19
  20. 20. Conclusions The Digital Environment’s Challenges• Technological advances and software engineering• Reuse of bibliographic records by multiple agents in the www• Information retrieval from different heterogeneity sources• Proliferation of volunteered geographic information• Semantics-based retrieval and navigation• The time and cost factors for anonymising, tranforming and delivering data remains as a major obstacle for most data providers.• Changes in data policies and revisions to standards also impose additional concerns on data developers• Issues regarding privacy and security (Keßler,e.a., 2009; Mathys and Kamel Boulos, 2011) 2nd IC-ININFO Budapest, 30 Aug - 2 Sept.,201 20
  21. 21. The main target the efficient use of geospatial informationSo, librarians should follow:• Good data management, and• Sharing practices 2nd IC-ININFO Budapest, 30 Aug - 2 Sept.,201 21
