title: Scale0 vector line of the Antarctic coastline - VERSION 1.0

description: This dataset consists of the first edition of the Antarctic Digital Database (ADD) coastline polyline dataset. A compilation of source data from eleven national mapping agencies at data scales no larger than 1:200,000/1:250:000. Line dataset was originally published on CD-ROM in 1993, 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.

The ADD project was first proposed in 1990 by a Cambridge (UK) based consortium comprising British Antarctic Survey (BAS), Scott Polar Research Institute (SPRI) and the World Conservation Monitoring Centre (now UNEP World Conservation Monitoring Centre(WCMC)). International participation in the project was agreed through the Scientific Committee on Antarctic Research (SCAR) and it's Working Group on Geodesy and Geographic Information.
 
'The majority of data capture and data management was undertaken in Cambridge, UK. Work was initially funded by BAS and by The British Petroleum Company p.l.c (BP). Other contributing nations sponsored their own data capture through either their national mapping agencies or their Antarctic research organisations. 

BP had no commercial interest in the project and the information gained from this database was in the public domain. BAS, SPRI, WCMC and SCAR, by entering into this project with BP, in no way implied their acceptance or endorsement of any exploration activity for oil, gas or minerals in Antarctica.

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 1993. The most recent version of the Antarctic Digital Database is available at: https://data.bas.ac.uk/collections/e74543c0-4c4e-4b41-aa33-5bb2f67df389/
description: Compiled using data from eleven national mapping agencies at data scales no larger than 1:200,000/1:250:000. Dataset was originally published in tiled Coverage format, using Esri ArcInfo. Data has now been merged to a single dataset using ArcMap v10.8 and exported to shapefile and geopackage formats. A number of slithers were removed from the merged data where source tiles were adjacent. Each polygon has a surface attribute (CST00SRF) indicating the type of feature it represents, ie. ice shelf, ice tongue. Data sources are dated between 1956-1990.

For full details on the dataset, including bibliography of sources, please refer to the ADD Manual v1.0: https://nora.nerc.ac.uk/id/eprint/517623/

Data attributes are:

- CST00TYP - Coastline type (denoted by code, outlined below)
- CST00DAT - Datestamp of source data
- CST00INF - Text field for notes and comments
- CST00SHT - Reference for map sheet of digitised source data
- CST00EDT - Data editor
- CST00SRC - Source of data
- CST00REV - Revision date of data

Coast types are defined using the 'CST00TYP' attribute, where: 
 
- 22010 - ice coastline (definite),
- 22011 - rock coastline (definite), 
- 22012 - grounding line (definite),
- 22013 - rock against ice shelf (definite),
- 22020 - ice wall (approximate),
- 22021 - rock coastline (approximate), 
- 22022 - grounding line (approximate),
- 22023 - rock against ice shelf (approximate), 
- 22030 - iceberg tongue
- 22040 - floating glacier tongue
- 22050 - ice shelf and front
- 22090 - ice rumples (distinct)
- 22100 - ice rumples (indistinct)
