  • Introducing ourselves:Who are we?What are we doing?
  • Implementing ISO TC211 work- an application-oriented view

Example 1: feature catalogueing – SCAR Feature CatalogueExample 2: metadata – SCAR KGIS Project

scar gig who are we
SCAR GIG: Who are we?
  • Scientific Committee on Antarctic Research (SCAR) is an inter-disciplinary committee of the International Council for Science (ICSU).
  • SCAR is charged with the initiation, promotion and coordination of scientific research in Antarctica.
  • SCAR also provides scientific advice to the Antarctic Treaty System(e.g. on environmental protection issues)
  • GIG stands for Geospatial Information Group
what are we doing
What are we doing?

Physical

Sciences

Life

Sciences

Geosciences

  • from mapping an unknown continent to modern GI technology framework
  • promulgation of cartographic standards for Antarctica since 1961
  • currently the endeavour in the GI programme is to providea spatial data infrastructure for Antarctica to support all scientific disciplines (policies and products)

what are we doing5
What are we doing?

GIG Terms of Reference:

  • To make fundamental reference data (geographic, geodetic, geophysical) available to the Antarctic and global user communities to meet scientific research requirements
  • Contribute to global geodesy for the study of the physical processes of the earth and the maintenance of the precise terrestrial reference frame
  • To integrate and coordinate Antarctic mapping and GIS programs
  • Provide a common geographic reference system for all Antarctic scientists and operators as the basis for sound data management
  • To establish and maintain strong links with all Antarctic science research groups and Antarctic data management groups
the challenge
The Challenge
  • research, logistics, politics, economic interest, SAR
  • political / administrative issues
  • still an comparably unknown and inaccessible continent
  • dynamic environment
  • our information community, the Antartcic Community, in fact is many communities:data producers from a broad range of agencies and institutions in many nationsdata custodians in a broad range of agencies and institutions(from large, powerful data centres to individual scientists)data users from a broad range of application fields (science, management, tourism, ...)

why do we need to standardize antarctica

80% of all data have a spatial component

Why do we need to standardize Antarctica?
  • The Vision:establish a distributed SCAR data and processing network for geospatial data

Example: spatially enabled RiSCC Biodiversity database

  • RiSCC project homepagehttp://www.riscc.aq
  • RiSCC biodiversity homepagehttp://www-aadc.aad.gov.au/biodiversity/

  • observation data, taxonomy, gazetteer, map catalogue bundled into one framework at AAD-AADC

standards and specifications
Standards and Specifications
  • open, non-proprietary, well-established technology
  • maturing of standards and specifications(SCAR GIG Liaision Member of ISO TC211)
standards and specifications18
Standards and Specifications
  • Example 1: SCAR Feature Catalogue build on 19110
  • Example 2: SCAR KGIS Project - A Testbed for 19115 Towards a Metadata Community Profile?
scar feature catalogue
SCAR Feature Catalogue
  • should provide common semantics
  • shoud be applicable to any scale of spatial information
  • should be applicable to any GIS package
  • should enable exchange of spatial information across disciplines / agencies / nations / cultures
scar feature catalogue20
SCAR Feature Catalogue
  • Part of SCAR Spatial Data Model project (under co-ordination of AAD)Goal:“To provide a SCAR standard spatial data model for use in SCAR and national GIS databases”
  • ISO 19110 compliant
  • Under construction!living document (http://www.antdiv.gov.au/default.asp?casid=6259; model@aad.gov.au)

  • in terms of implementation seems to provide a flexible enough framework
  • in terms of acceptance the ‘ ISO branding’ might become very helpful

King George Island

  • several nations operate permanent bases
  • important hub to Antarctic Peninsula
  • focal point of scientific activities
  • shipborne / airborne tourism
  • protected areas
  • complex context but apparent need for co-ordinated management(SCAR recommendations Tokyo 2000)
goal of the kgis project
Goal of the KGIS project

To produce an integrated geographic database

  • for use by all countries
  • for use in multi-disciplinary applications:
    • planning and coordination of activities
    • environmental impact assessments
    • scientific database
    • management plans (SSSIs, ASMA)

metadata whithin kgis database
Metadata whithin KGIS database
  • comes typically sparse & incomplete
  • SCAR adopted standard is DIF (Antarctic Master Directoy is part of Global Change Master Directory)
  • some institutions have strict standards
  • some institutions have no standards at all
  • most important source for metadata typically is personal communication with data producers
  • we started to construct comprehensive metadata records based on 19115
  • these are provided as XML, HTML and text files to the users
  • positive feedback if tools to easily access the information are at hand
  • growing acknowledgement of the importance of metadata
antarctic metadata and iso 19115
Antarctic Metadata and ISO 19115
  • an ISO 19115 compliant community profile appears to be very helpful in integrating exisiting metadata / metadata standards
  • tools for user oriented metadata presentation help in raising awareness of the fact that metadata actually is part of the data
  • this might help to stimulate the production of metadata records useable for a distributed data and processing environment
conclusions from our application oriented point of view
Conclusionsfrom our application-oriented point of view
  • users / producers slowly start to realize how they benefit from and why they should adhere to standards
  • looking at the implementation of some ISO TC211 based standards:technically: works, but of course the devil’s in the details ...application-oriented: break the communication barrier!
