  1. Quantarctica:A free GIS package for research, education, and operation in Antarctica

  2. Quantarctica • Works with free software Quantum GIS. • Includes a range of geographical data. • Requires no internet access for the daily use, i.e. suitable for operation in Antarctica. • Is able to plot GPS-provided current positions together with GIS layers. Nice for research/operation in Antarcticaas well as education.

  3. What’s really unique? • Uniform map projection for all datasets • Optimized file size for satellite images • Sophisticated cartography • Capabilities to add your own data layers on Quantarctica and make your own GIS package.

  4. A ”ready-to-go” package This morning, to make a sandwich,you started with bread, not flour. Whydo you start with flourto do your job?

  5. Developer team at NPI Anders Skoglund Angelavon Deschwanden KennyMatsuoka - Previous versions were tested more than 2 years. - Now Quantarctica version 1.0 is publicly released and will keep growing as a community effort.

  6. Quantum GIS • Open source (GNU) • First release in 2002. • Regular updates. • Numerous plugins. • Activecommunitysupport. • http://www.qgis.org/

  7. Screenshot: detailed basemap You have simple continet-wide and informaiton-rich close-up views.

  8. Import of high-res satellite images High-resolution satellite imagenary can be imported with few clicks.

  9. Attribute table A right click gives an easy access to attributes of each facility (layer)

  10. Print composer High-quality figures for publications can be easily made

  11. Data currently available on QA (1) Glaciology Ice flowvelocity Bed elevation Ice thickness Grounding line Subglacial lakes various more

  12. Error layers Ice-flowspeed Ice thickness More transparent cells have more confident estimates

  13. Data currently available on QA (2) Glaciology Ice flow velocity Bed elevation Ice thickness Grounding line Subglacial lakes Surface elevation Geothermal flux Surface mass balance • Surface temperature various more

  14. Data currently available on QA (3) Geophysics Magnetic anomalies Gravity anomalies Geoid heights

  15. Data currently available on QA (4) Sea Ice Monthly sea ice extent

  16. Plugins: an example Profile plugin extracts digital values (e.g. elevation) from raster data

  17. Metadata and references Eachlayer has a descriptionincludingreferences Abstract: The surfacetemperatureestimates in °C arederived from AVHRR infrared data.

  18. Supporting community effort • It’s a community effort. • Layer contributions are expected. • Data layers particularly for oceanography, geology, meteology, biology, …. • Model-output layers for any disciplines. • ML annoucning updates (please register yourself at the web site below).
