High resolution vector polygons of Antarctic rock outcrop - VERSION 7.10

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.
