1 Glenn Johnstone / John ManningAGS 2002, Wellington, New Zealand Report on Geodetic Control Database project activities (since XXVII SCAR July 2002)

2 Glenn Johnstone / John ManningAGS 2002, Wellington, New Zealand History of Project Led by NZ from Lack of resources/personnel to continue project - Australia assumes responsibility GA develops database from existing control received On-line version live in March 2002

3 Glenn Johnstone / John ManningAGS 2002, Wellington, New Zealand 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"

4 Glenn Johnstone / John ManningAGS 2002, Wellington, New Zealand Mapserver Open source code developed by University of Minnesota – Freely available OGC compliant software –ISO TC211 compliant Projection file for Antarctica has been developed

5 Glenn Johnstone / John ManningAGS 2002, Wellington, New Zealand Project Work Plan 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

6 Glenn Johnstone / John ManningAGS 2002, Wellington, New Zealand Activities since Shanghai Received 50 new points from BAS - field seasons 98-99, & 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

7 Glenn Johnstone / John ManningAGS 2002, Wellington, New Zealand Database details

9 Glenn Johnstone / John ManningAGS 2002, Wellington, New Zealand

10 Glenn Johnstone / John ManningAGS 2002, Wellington, New Zealand Future Activities Acquire more data from GSSG members (inc. KGI control) Publish guidelines for geodetic control identification on the web Other suggestions?
