SCAR Antarctic Digital Database (ADD) www.add.scar.org
A compilation of the best international topographic mapping for Antarctica at scales between 1:250,000 and 1:10 M that can be viewed on a range of vector and satellite image backdrops. The underlying data can be downloaded free of charge in a range of formats for onward work in desktop GIS.
SCAR Composite gazetteer https://data.aad.gov.au/aadc/gaz/scar/
A searchable database of all Antarctic place-names from each country active in Antarctica.
SCAR map catalogue https://data.aad.gov.au/aadc/mapcat/
This catalogue of international maps for Antarctica is compiled and maintained by the Australian Antarctic Division Data Centre. It contains entries for over 5000 hard copy maps from 26 countries and about 1000 digital maps from five countries. Some maps are available for download at full resolution, but the majority have only a low-resolution quicklook and metadata including contact information to access them.
UK Antarctic Place-names Committee website http://apc.antarctica.ac.uk/
A web-based, searchable map of the British Antarctic Territory and SGSSI place-name gazetteers, giving information on the location and description of the feature. Each of the place-name datasets is available to download. There is also information on how to propose new place-names, the role of the UK-APC, and links to other Antarctic place-naming organisations.
Arctic web-map http://map.arctic.ac.uk/home
A web-based GIS providing access to environmental information and human activity in the Arctic, layered on a topographic mapping backdrop. The map is a useful planning tool for Arctic research projects and all of the base data is available to download.
CCAMLR web-GIS https://gis.ccamlr.org
Web map based system developed to showcase CCAMLR fisheries data. Initially developed and populated with data at BAS, it is now maintained by CCAMLR staff in Hobart.
Landsat Image Mosaic of Antarctica (LIMA) http://lima.usgs.gov
A seamless mosaic of over 1000 15 metre resolution Landsat-7 images of Antarctica, acquired between 1999 and 2003. Compiled by BAS, NASA and US Geological Survey. It provides cloud-free coverage of the whole continent and is available as natural colour and false colour mosaics and with a range of contrast stretches. GIS-compatible image data can be downloaded from the LIMA website or through the ADD.
Access to recent satellite radar images of sea ice density and distribution, and sea ice charts, for the southern ocean and arctic regions. Image data can be downloaded in a range of formats and optimised for low-bandwidth links. The images are also very useful for ice-shelf fronts and internal structure.
South Georgia GIS SG-GIS www.sggis.gov.gs
A web-based GIS providing access to environmental information for South Georgia layered on topographic mapping and satellite image backdrops. It includes the South Georgia and South Sandwich islands place-names gazetteer. The underlying data is available for download free of charge in a variety of formats for onward work in desktop GIS. Free registration is required.
