High resolution dataset of rock outcrop in Antarctica. Data have been prepared from various map and remotely sensed datasets ranging from 1990s-2019. 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 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.
