Quantarctica is a collection of Antarctic geographical datasets which works with the free, open-source software Quantum GIS. The package is freely available for non-commercial use in research, education, and operation in Antarctica. It was originally developed for in-house use at the Norwegian Polar Institute. Development on a public version started in 2012, and the first version was released in 2013.
The base package v1.0 is about 7gb and the zip file includes:
- Imagery: LIMA mosaic, MODIS mosaic, RADARSAT mosaic, index files (for Landsat CIRREF, MOS and RADARSAT tiles), Landsat CIRREF tiles, and ancillary files. 3.3 GB in total.
- Terrain: Digital elevation models (ETOPO1, RAMP2, Bamber), hillshades and elevation contour lines (at 100, 200, 500 and 1000 m intervals). 990 MB in total.
- Vector: Detailed vector basemap data (ADD). 1.5 GB in total.
- World: Low resolution satellite imagery mosaic (NASA BMNG), countries dataset, geographic lines. 4 MB in total. Not loaded in project file.
- Miscellaneous: Place names (SCAR CGA), facilities (COMNAP-listed), graticules, UTM zones and simple basemap. 70 MB in total.
- Geophysics – Magnetic anomaly (ADMAP), Gravity amality (GOCE), Geoid height (GOCE). 15 MB in total.
- Glaciology – Subglacial lakes (various sources), Grounding and hydrostatic lines (ASAID), ALBMAP compilation, BEDMAP2, Flow speed. 1 GB in total.
- Quantum GIS 1.8 Windows installer, selected plugins and software user guide, Antarctic facts. 140 MB in total. (You can also find Mac OSX, Linux/Unix and Android versions of Quantum GIS at its official website)
High-resolution satellite images
High-resolution Landsat MOS and RADARSAT images are available in two ways:
- For specific areas of Antarctica: you can download individual satellite images from within Quantarctica. See the “Add high-resolution satellite imagery” section in the Quantarctica manual for details. Each Landsat MOS image typically covers 150 km by 150 km and RADARSAT does 500 km by 500 km.
- For a larger area or for the entire Antarctica: use a ftp client software like Filezilla to download the images:
See Quantarctica’s manual (PDF, 0,5 MB) for installation details and how to optimize Quantum GIS for the use with Quantarctica.
