  3. How it works • Using tabulated data collected, it is transformed into ArcView Shape files and then into Mapserver compatible format (.dbf files) • MapServer is not a full-featured GIS system but allows you create "geographic image maps" AGS 2002, Wellington, New Zealand

  4. Mapserver • Open source code developed by University of Minnesota • <mapserver.gis.umn.edu> • Freely available • OGC compliant software • ISO TC211 compliant • Projection file for Antarctica has been developed AGS 2002, Wellington, New Zealand

  5. Project Work Plan 2002-04 1. Maintain database and add in newly acquired data 2. Italy to provide further details on Northern Victoria Land points (photos, etc) 3. Collaboration with Steffen Vogt for KGI geodetic control 4. Australia (Henk Brolsma & John Manning) to help develop guidelines for photo identification (collaboration from Jerry Mullins) 5. Publish guidelines for geodetic control identification on the web site AGS 2002, Wellington, New Zealand

  6. Activities since Shanghai • Received 50 new points from BAS - field seasons 98-99, 00-01 & 01-02 • Updated in the on-line database • Information on Northern Victoria Land markers is being sent by Alessandro Capra • Information on photo identification is being sought AGS 2002, Wellington, New Zealand
