John Manning XXVII SCAR Shanghai, China, July 2002

SCAR Working Group on Geodesy & Geographic Information (WG-GGI)


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


WG Structure

Has evolved using umbrella groupings :

• GIANT for Geodesy related activities

• GIP for Geographic Information

• Outreach program for administration

and communication


GIANT Projects 2000-02

• Permanent Observatories

• Remote observatories

• GPS campaigns• Physical Data

BasesURL www.scar-ggi.\

geodesy\giant.htm

• Ground truthing for earth sensing satellite missions

• GPS and the Atmosphere

• Tide gauges• Geodetic control

Data Bases


Geographic Information Projects 2000-2002

• Spatial standards for GIS

• SCAR Place names on line gazetteer

• SCAR Digital Topographic data base

• KGI GIS• On line national

atlases

• On line Mapping Catalogue

• Bathymetric data base of southern ocean• SCAR Cybercartographic

atlas on line• ANT Imagery catalogue• East Antarctic GIS


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


Meetings 2000-2002• Program

coordinators Italy(at ANTEC) July 2001

• Geographic Information program workshop

• AGS00 & AGS01• Place Names

specialists meeting

• 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


Antarctic GPS base stations

• Data from Red dots available through IGS

• Data from blue dots available on request from individual researchers

time series


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


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


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


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 40+years.

• Future reporting will be through the Geoscience Scientific Standing Group
