Abstract:
A very incomplete dataset of surface lakes in Antarctica. Data have been prepared from various map and remotely sensed datasets. This dataset has been generalised from the high resolution version.
Changes in v7.10 include new data for the South Orkney Islands and small regions of the Nordenskjold coast.
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 lakes in Antarctica, due to the age and quality of the data. | |
|---|---|---|
| Lineage: | Data compiled from various mapping and remote sensing sources. Exact data sources and dates are contained within the attribute table of the data. This medium resolution version has been generalised from the high resolution version. All polygons <0.02 km2 were deleted and the 'smooth polygon' tool was 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. |
