Presentation Transcript

  1. Digital Gazetteer Information Exchange • NSF-sponsored DGIE workshop, October 1999, at the Smithsonian Institute (Hill & Goodchild, co-PIs) • 66 participants from academic, state and federal government, and commercial sectors; international representation • Presentations and final report have been published online at www.alexandria.ucsb.edu/gazetteer/dgie/DGIE_website/DGIE_homepage.htm • On-going activity to develop gazetteer service query and response protocols through OpenGIS

  2. DGIE Workshop Purpose • Develop an understanding of the potential of indirect spatial referencing of information resources through geographic names • Identify the research and policy issues associated with the development of digital gazetteer information exchange

  5. Highlights from the DGIE Workshop • Acknowledgement of the immediate opportunity and requirement to coordinate the building of shareable digital gazetteer data in the interest of digital earth applications • The importance of the temporal aspects of gazetteer data • The need for a gazetteer service protocol to support distributed gazetteer services

  6. Summary of Workshop Outcomes • Key everyday life tool - embedded in many applications - early education component • Enable publishing of digital gazetteers - commercial, personal, group • Access to gazetteer data embedded in other products (e.g., GIS datasets) • Footprint representation • Fuzzy locations • “Sufficing” of generalized footprint for IR - related to use and scale • More feature extents

  7. Summary of Workshop Outcomes • Seamless access to digital government data through indirect geographic referencing (place names) • Geo-name Services • import and export gazetteer data • distributed, interoperable gazetteer model (query-response protocols) • registry service for gazetteer data/service • gazetteer creation tools

  8. Summary of Workshop Outcomes • Policy issues • security and confidentiality authentication (digital signature) • intellectual property, rights (constraints) • attribution, provenance, authority, confidence (level of trust) • indication of quality (name, footprint, …) • currentness • Evaluation of uses of gazetteer services • User communities, current and potential uses • Interaction modes, scenarios of use

  9. Preliminary View of Workshop Outcome • Multicultural issues • Language and alphabet • Cultural sensitivity • Collaborations - Partnerships • Other: sustainable systems, duplicate management, registries (inventories)
