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.
