1. Report to SCADM September 2011 SCAR Standing Committee on Antarctic Geographic Information (SCAGI) Adrian Fox (BAS)

2. Purpose of SCAGI 1) Provide high-quality Geographic Information products for the Antarctic community – both Science and Operations High quality = useful, accurate, reliable, up-to-date, accessible, standards-compliant, inter-operable 2) Provide arena for arranging international collaboration: new projects, best practice, international reports 3) Through 1) and 2) support the international leadership role of SCAR

3. SCAGI products SCAGI is responsible for four SCAR Community Projects: SCAR Antarctic Digital Database SCAR Composite Gazetteer of Antarctica SCAR Map Catalogue SCAR Feature Catalogue Notable international collaborations in the SCAGI arena: Landsat Image Mosaic of Antarctica (LIMA) Scanning historic aerial photography archive

4. Progress with Antarctic Digital Database New ice shelf coastline from ENVISAT (PolarView) Updated grounding-line based on boundary of contiguous grounded ice from NASA ASAID project Antarctic Peninsula upgraded with new 1:250,000 scale mapping from BAS and new coastline BAS/Swansea Metadata for existing information as a database to conform to SCAR DIMS (legacy issue from early 1990s) Improved access – web-download in ESRI shapefiles Seamless compilation of best international mapping

5. Progress with Antarctic Digital Database 682 new registrations for download since June 2009 Immediate future plans: Include BEDMAP 2 Include new topographic data as/if available……. Longer-term objectives: Improve rock outcrop Improve elevation for mountains – GDEM, Tandem-X

6. Progress with Composite Gazetteer Allows features to be unambiguously identified Shows which features already named and dont need new names Unique identifier shows names that refer to the same feature, despite multiple names and different coordinates 36,722 names for 18,715 features – multiple naming, worst case 7 names for same feature, 3 names common The SCAR Composite Gazetteer of Antarctica (CGA) is a compilation of the national gazetteers

7. Progress with Composite Gazetteer 525 names for 435 new features since June 2009 Most active: Bulgaria; China; UK; USA; Australia Harmonisation of under-sea names with GEBCO Current and future plans: Continue to add new names, update coordinates Checking against LIMA, convergence of names eg DML (LIMA = Landsat Image Mosaic of Antarctica) publish a recipe to do this

8. Progress with Antarctic Map Catalogue 5,155 hard-copy maps from 26 countries 947 digital maps from 5 countries 1,515 hard copy and 249 digital maps since June 2009 9,856 downloads since June 2009 Online catalogue showing all known international maps Search tools and detailed metadata for entries

9. Progress with Feature catalogue Completed Developed by AAD and mainly used by them Other organisations often working in own protocols Detailed definitions of Antarctic geographic features that can be used to represent them in GIS software

10. Progress with Aerial photography scanning Large international archive of aerial photography back to 1940s – incredible resource for environmental change Risk of loss, deterioration – scan to secure Digital data easier to access USGS scanning own archive and key parts of others 330,000 US scenes, 10s of 1000s UK and Australia USGS and PGIC Minnesota flight-lines and web- download International campaign, led by USA, to scan archive of historic aerial photography

11. SCAGI objectives 2011-2013 Continue to develop products: ADD, CGA, MapCat Redevelop website in time with SCAR website (2012) Improve awareness with user community SSGs and COMNAP: Comment on developing SCAR science programmes, input to SRP planning meeting Modena, Feb 2012. Antarctic Treaty paper on SCAR products as a platform to build links with COMNAP Complete scanning of historic aerial photography and implement delivery systems (2012) Next meeting Portland, 2012
