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. Data has now been merged to a single dataset using ArcMap v10.8 and exported to shapefile and geopackage formats. Each line has attributes detailing the date ('CST00DAT'), and sources ('CST00SHT' and 'CST00SRC'). Data sources are dated between 1956-2007.
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)
