SCAR Working Group on Geodesy

SCAR Working Group on Geodesy Geographic
Information (WG-GGI)
2
Background to GGI

• 1959 WG Cartography formed
• 1961 Geodesy and Cartography formed
• 1988 name change to Geodesy and Geographic
  Information
• Chaired By Australia since 1961
• 24 member countries and observer members from
  IHO, IAG, FIG, ISCGM (Global Map), GEBCO, JCADM
  COMNAP

Objectives of WG-GGI

• Provide support to Antarctic science in mapping
  and positioning in an unknown continent
• Coordination standardisation of surveying and
  mapping activities
• To produce guidelines for map production (incl.
  GIS) and collection of geodetic data
• To produce and make available homogenous datasets
  of Antarctica

4
WG Structure

• Has evolved using umbrella groupings
• GIANT for Geodesy related activities
• GIP for Geographic Information
• Outreach program for administration
• and communication

• URL www.scar-ggi.\geodesy\giant.htm

• Ground truthing for earth sensing satellite
  missions
• GPS and the Atmosphere
• Tide gauges
• Geodetic control Data Bases

Outreach Program

• Website building and maintenance
• newsletters (7500 individual users accessed the
  site in the period
• arrange symposia and publication of papers
  (eg-Warsaw and St Petersburg)
• Post guidelines for specific geodetic activities
• Liaise with ISCU bodies and other NGOs

8
Meetings 2000-2002

• Special Antarctic geodesy session (with ANTEC) at
  EGS01
• Two Cybercartographic Atlas workshops - Argentina
  and Canada
• Informal meeting and papers presented at AGU2002
  and EGS 2002

• Program coordinators Italy(at ANTEC) July 2001
• Geographic Information program workshop
• AGS00 AGS01
• Place Names specialists meeting

Antarctic GPS base stations

• Data from Red dots available through IGS
• Data from blue dots available on request from
  individual researchers

WG-GGI Accomplishments

• On line composite Gazetteer of Antarctic Place
  names (17,000)
• Five major editions of a Catalogue of Antarctic
  Maps and Charts
• SCAR Antarctic Digital Database
• Mapping standards (now spatial data standards for
  GIS)
• Common Geodetic datum as positional basis for all
  homogeneous spatial data

14
WG-GGI Accomplishments

• Encouragement of involvement in international
  cooperative projects
• Freeing up data through technology transfer
• Transition to Internet based communication- WG
  web site for past three years with listserver and
  newsletters

15
Outcomes from Shanghai WG-GGI

• Recommends that the group is not disbanded
  immediately but continues as an group of experts
• Recommends that all live projects be carried
  forward
• Recommends that the scope of the group be
  expanded to include Geospatial information
• Recommends that links be formally established to
  other SSGs, SCAR Standing Groups (COMNAP data
  groups) in a new structure

16
Finally

• The last meeting of the autonomous Working Group
  of Geodesy and Geographic Information closed at
  1700 on Tuesday 17th July 2002 after a continuous
  and productive life of 40years.
• Future reporting will be through the Geoscience
  Scientific Standing Group
