Items:

Topics:
Topographic Mapping

Summary

The Scientific Committee on Antarctic Research (SCAR) Antarctic Digital Database (ADD) aims to provide seamless topographic datasets compiled from the best available geographic information. It covers Antarctica south of 60°S.

The SCAR ADD consists of the following datasets, available to download from this catalogue:

  • coastline, including grounding lines and ice shelf fronts
  • rock outcrop
  • contours
  • lakes
  • moraine
  • streams
  • seamask
  • ADD data limit at 60°S

The ADD is managed by British Antarctic Survey, see the website for more information on the project.

The ADD map viewer also displays supplemental datasets to provide context to the ADD datasets. You can download these here.

High resolution vector contours for Antarctica

Version:
7.3
Released:
2020-11-04T13:45:03

A continuous contour dataset at 100 m intervals for all land south of 60°S, excluding the Balleny Islands. The vertical datum of the contours is EGM2008. Contours are extracted primarily from the PGC Reference Elevation Model of Antarctica (REMA) v1.1 with certain islands filled from Copernicus WorldDEM. Further small areas are interpreted from satellite imagery, and Peter I Øy contours are from the Norwegian Polar Institute. Sources of individual line segments are contained in the attribute table and full compilation information is given in the lineage statement.

Note: contours overlap the coastline in small areas, due to resolution of the data used in creation of the lines, and potential errors in coastline and/or contour data. Certain areas are known to contain erroneous data due to faults in the original DEM data.

A continuous, smoothed contour dataset at 500 m intervals for all land south of 60°S, excluding the Balleny Islands. The vertical datum of the contours is EGM2008. Contours are extracted primarily from the PGC Reference Elevation Model of Antarctica (REMA) v1.1 with certain islands filled from Copernicus WorldDEM. Peter I Øy contours are from the Norwegian Polar Institute. Sources of individual line segments are contained in the attribute table and full compilation information is given in the lineage statement.

Automatically extracted rock outcrop dataset for Antarctica

Version:
7.3
Released:
2020-11-05T08:58:10

A rock outcrop dataset for all of Antarctica, automatically extracted from Landsat 8 imagery. The original dataset was published in the following paper 'An automated methodology for differentiating rock from snow, clouds and sea in Antarctica from Landsat 8 imagery: a new rock outcrop map and area estimation for the entire Antarctic continent', The Cryosphere, 10, pp1665-1677, doi:10.5194/tc-10-1665-2016. This version has been updated in places to match the current coastline, and areas outside of the ADD data limit have been removed.

High resolution vector polygons of Antarctic rock outcrop

Version:
7.3
Released:
2020-11-05T08:59:56

High resolution dataset of rock outcrop in Antarctica. Data have been prepared from various map and remotely sensed datasets ranging from 1960s-2019. The large majority of data was compiled in 1993 and the quality and accuracy is uncertain. The automatically extracted rock outcrop layer provides a more accurate dataset in most locations.
