Sneak Preview:The New US Geospatial Metadata Standard

GeoMaximFederal Geographic Data Committee (FGDC)

Lynda Wayne, GISPSharon Shin

slide2
The US is in the final stages of adopting a national geospatial metadata standard. While the FGDC geospatial metadata standard was a federal standard recognized by most state and local governments, the forthcoming standard will be an American National Standards Institute (ANSI) implementation of the International Organization for Standardization (ISO) Geographic Information - Metadata (standard). This new standard, while based heavily on the FGDC Content Standard for Digital Geospatial Metadata (CSDGM) version 2.0, introduces new formats and content that incorporate more robust data structures, e.g. flexibility, while at the same time addressing the need for increased standardization in individual element values, e.g. domains. Get a sneak preview of these new features as well as the draft guidance workbook under development by the FGDC.

we are here

  • North American Profile (NAP) Status
    • US is in the final is in the final stages of adopting a national geographic metadata standard
    • Content Standard for Digital Geospatial Metadata aka ‘FGDC’ metadata standard is a federal standard
    • NAP is an American National Standards Institute (ANSI) standard with broader applicability
    • ANSI approval is expected in early 2009

scale determined by ISO, ANSI, INCITS L1 and various other acronyms

slide4
Transition to the NAP
    • transition will be staged as it as with the FGDC standard
      • apply to new metadata records
      • translate existing metadata records
    • FGDC is working with NSGIC, URISA and others to develop effective transition strategies
    • translation applications under development by FGDC, Intergraph, ESRI and several international metadata application developers

CSDGM

NAP

new or robust sections
New or Robust Sections
  • - Resource Maintenance
    • added functionality
  • - Data Quality
    • increased structure
slide6
What’s New with the NAP?
  • New Elements
    • International elements
      • Data / Metadata Language
    • Technical elements
      • Character Set Encoding
    • Extended elements
      • CSDGM = geographic and temporal extent
      • NAP = geographic, temporal, & Vertical Extent
    • Needed elements
      • Topic Category– 19standardized subject categories to facilitate data discovery
slide7
What’s New with the NAP?
  • Conditionality
    • Fewer mandatory elements
      • Core contains only 7 mandatory elements
      • Dataset Title
      • Dataset Reference Date
      • Dataset Language
      • Dataset Topic Category
      • Abstract
      • Metadata Point of Contact
      • Metadata Date Stamp
    • ...includes far more optional elements
slide8
What’s New with the NAP?
  • Domains
    • More standardized domains and code lists in place of free text to control vocabulary and improve discovery
      • Contact Role = author, distributor, custodian, point of contact…
      • Topic Category = transportation, environment, elevation, biota….
      • Online Function = download, information, offline access…
      • Keyword Type = theme, place, stratum, temporal…
      • Maintenance Frequency = continual, daily, weekly, annually…
      • Progress = completed, archived, obsolete, ongoing, planned…
      • Topic Category = transportation, environment, oceans, biota…
slide9
What’s New with the NAP?
  • Content
    • Includes elements to document geospatial services
      • Web Mapping Services
      • Geospatial Data Catalogues and Portals
      • Other
    • Does not CURRENTLY include Entity & Attribute documentation
      • documented by ISO 19110: Feature Catalog
      • NAP team intends to extend NAP to include Feature Catalog in next version
slide10
What’s New with the NAP?
  • Multilevel Metadata
    • Metadata can be created for:
      • Data Series - wetlands
      • Dataset - Paducah wetlands
      • Feature Type - marsh
      • Feature Instance - Mandy’s Marsh
      • Attribute Type - salinity
      • Attribute Instance - actual % water salinity
