Scale0 vector polygon of the Antarctic coastline - VERSION 3.0

High resolution (Scale0) polygon dataset of the Antarctic Coastline. 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 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 v3.0.

Changes in ADD Version 3.0 included amendments to ice shelf positions, including many other minor corrections. These are available to view in detail in the ADD Manual (link).

Funding was received from Scientific Committee for Antarctic Research (SCAR) in 1999 which enabled British Antarctic Survey (BAS) to compile, manage and distribute the ADD.

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 2000.
