Abstract:
An incomplete dataset of moraine in Antarctica. Data have been prepared from various map and remotely sensed datasets. This dataset has been generalised from the high resolution version but there are some inconsistencies in this dataset and the high resolution version is recommended.
Changes in v7.10 include new data for the South Orkney Islands.
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.

| Quality: | This dataset might not comprehensively contain all moraine in Antarctica, due to the age and quality of the data. | |

| 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 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. The data newly added for the v7.10 release (South Orkney Islands) was generalised from the high resolution version by deleting polygons < 0.02 km2 in size and the 'smooth polygon' tool was then used in ArcGIS with the 'PAEK' algorithm and a smoothing tolerance of 200 m. Please note: due to the versioning of the ADD, there are no versions 7.4-7.9 for this specific dataset. |
