Description: Abstract

Medium resolution dataset of rock outcrop in Antarctica. Data have been prepared from various map and remotely sensed datasets ranging from 1960s-2019. This dataset has been generalised from the high resolution version. The large majority of data was compiled in 1993 and the quality and accuracy is uncertain. The automatically extracted rock outcrop layer provides a more accurate dataset in most locations.

Data compiled, managed and distributed by the Mapping and Geographic Information Centre and the UK Polar Data Centre, British Antarctic Survey on behalf of the Scientific Committee on Antarctic Research.


Further information and useful links
Map projection: WGS84 Antarctic Polar Stereographic, EPSG 3031. Note: by default, opening this layer in the Map Viewer will display the data in Web Mercator.  To display this layer in its native projection use an Antarctic basemap.

The currency of this dataset is May 2020 and is reviewed every 6 months. This feature layer will always reflect the most recent version.

For more information on, and access to other Antarctic Digital Database (ADD) datasets, refer to the SCAR ADD data catalogue.

For background information on the ADD project, please see the British Antarctic Survey ADD project page.


Lineage

Data compiled from various mapping and remote sensing sources. Exact data sources are currently missing from the attribute table for the majority of data – the large majority was compiled in 1993 digitized from the USGS 1:250k reconnaissance series maps dating from 1960s-1990s and DOS 1:250k series maps dating from 1960s and 1970s. Exact data sources can be provided on request in the format of vector lines.
