High resolution vector polygons of Antarctic rock outcrop - VERSION 7.10

A new version of this dataset exists. To see the last version of the Antarctic Digital Database, have a look here: https://data.bas.ac.uk/items/e74543c0-4c4e-4b41-aa33-5bb2f67df389/

High resolution dataset of rock outcrop in Antarctica. Data have been prepared from various map and remotely sensed datasets ranging from 1960s-2023. 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.

Changes in v7.10 include new data for the South Orkney Islands. Source attributes have also been added for some of the older data, although many are still missing. See the lineage for further details.

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.

Statement

Methodology:

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 majority was compiled in 1993 and 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.

The data newly added for the v7.10 release (South Orkney Islands) was automatically extracted and then manually edited from Sentinel-2 satellite images. The exact image IDs and acquisition dates can be found in the attribute table of the dataset.

Please note: due to the versioning of the ADD, there are no versions 7.4-7.9 for this specific dataset.
