Webinar Goals
In the next 60 minutes, we’ll use a case study approach to learn how to…
1. Navigate Quantarctica’s data package in QGIS
2. Import and convert between different scientific
data formats
3. Analyze and manipulate scientific and basemap
data
4. Use cartographic design principles
5. Create a production-quality map or figure
Technical Notes
• A current version of QGIS (2.18.x) installed and
running on a stable computing environment
• Already downloaded and extracted the full
Quantarctica data package (7GB)
• The workshop_data.zip
[http://tinyurl.com/qaegu17data,
package downloaded and extracted to the
5.4MB ZIP]
Quantarctica project folder

What’s inQuantarctica?
Complete datasets, stored on your hard drive, at full quality and in open data formats, with no internet access
required after installation. Copy, modify, redistribute, and mash it up with your own scientific data –every dataset is
open access, and full citation information and metadata is always included.
• Continent-wide satellite imagery • Antarctic and sub-Antarctic coastlines and
(Landsat, MODIS, RADARSAT) outlines for exposed rock, ice shelf, and
subglacial lakes
• Digital elevation models and/or contour
lines of bed and ice-surface topography and • Magnetic and gravity anomalies
seafloor bathymetry
• Ice flow velocities, catchment areas, mass
• Locations of all Antarctic research stations balance, and firn thickness grids
and every named location in Antarctica
(SCAR Composite Gazetteer of Antarctica)
Basemap Topography Satellite Imagery

The Final Product
The Map/Figure will…
• Show imported and converted data
• Use Basemap data from the
Quantarctica data package
• Use at least one scientific dataset
from the Quantarctica data package
• Be a functional, good-looking map
that you hopefully feel proud of!
