Abstract
The second edition of the Antarctic Digital Database (ADD) coastline polygon dataset. A compilation of source data from eleven national mapping agencies at data scales no larger than 1:200,000/1:250:000. Polygon dataset was originally published on CD-ROM in 1998, in tiled Coverage format. Data has since been converted and merged to a single dataset and exported to shapefile and geopackage formats. Scale0 is the highest resolution that was produced.
Each polygon has a surface attribute (CST00SRF) indicating the type of feature it represents, ie. ice shelf, ice tongue, land, ocean and rumple.
For information on source of polygon delineations, refer to coincident features in the polyline dataset, Scale0 vector polylines of the Antarctic coastline v2.0.
ADD Version 2.0 contained many amendments to the original data. Most corrections were made in Quadrant 4, which covers the Antarctic Peninsula, parts of Ellsworth Land and Coats Land. A few features such as Doake Ice Rumples, were inadvertently omitted from ADD Version 1.0, so were included in this version for the first time. Data for the Ronne and Filchner ice shelves were also upgraded. A new map of James Ross Island was incorporated, and the positions of ice fronts of the northern Larsen Ice Shelf, Wordie Ice Shelf and Wilkins Ice Shelf were also amended using the latest available information. Other minor changes were also made and documented in the ADD Manual (https://nora.nerc.ac.uk/id/eprint/536533/).
The UK Consortium behind the ADD Version 1.0, passed the ongoing maintenance and revision of the ADD to British Antarctic Survey (BAS) for Version 2.0.

Due to the very wide and legacy sources of the data for this compilation, the dataset attributes are inconsistent in format and incomplete. The data are published as they stood at the time of their first publication in 1998.
