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.

| Lineage: | 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 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. | |
