Abstract:
Medium resolution dataset of rock outcrop in Antarctica. Data have been prepared from various map and remotely
sensed datasets ranging from 1960s-2025. 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.
Changes in v7.11 include new data for the area between 20°W and 80°W and as far south as 82°. `sourcedate` and
`revdate` attributes were updated to a consistent YYYY-MM-DD format. To indicate limited date precision for
earlier records, `sourceprec` and `revprec` attributes were introduced.
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.
Purpose:
Generalised rock outcrop in Antarctica derived from maps and remote sensing data from 1960-2025. Primarily
compiled in 1993 with uncertain quality and accuracy.

Statement:
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 the 1960s to 1990s, and DOS 1:250k series
maps dating from the 1960s and 1970s. Exact data sources can be provided on request in the format of
vector lines.
The data newly added for the v7.11 release (the area between 20°W and 80°W and as far south as 82°, except
for South Orkney Islands, north of Clarence Island, Deception, Seymour, and Cockburn Islands, and
Rothera Point) was generalised from the high resolution version by deleting polygons < 0.02 km2 in size
and smoothing the polygons. The exact source with the corresponding `sourcedate` attribute can be found
in the attribute table of the dataset. Additionally, the `sourceprec` field, identifying source time
precision (day, month, or year), is provided. The `revdate` field with the corresponding `revprec`
attribute identifies the date of data revision.
Please note: due to the versioning of the ADD, there are no versions 7.4-7.9 for this specific dataset.
