Abstract:
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.
Data compiled, managed and distributed by the Mapping and Geographic Information Centre and the UK Polar Data
Centre, British Antarctic Survey on behalf of the Scientific Committee on Antarctic Research.
Purpose:
Continuous, smoothed 500m interval contours for land south of 60°S, generated from REMA v1.1 and other sources.

Statement:
All processing described here was performed in ArcGIS Pro version 2.6.
A composite Digital Elevation Model (DEM) was created comprising of three datasets from the Reference
Elevation Model of Antarctica v1.1: ‘REMA_100m_peninsula_dem_filled’, ‘REMA_100m_dem’ and
‘REMA_200m_dem_filled’. These DEMs were first converted from ellipsoidal height to height above EGM2008
geoid and then mosaicked together in respective order at 100 m spatial resolution. This 100 m DEM was
smoothed by performing ‘Focal Statistics’ using a 40x40 cell size.
500 m contours were extracted and all contours with a height <1m were deleted, as well as erroneous
offshore contours. In certain locations, primarily some islands on the Antarctic Peninsula, REMA data
was insufficient to produce contours. In these places, contours were produced from the ‘Copernicus
WorldDEM 90m’ DEM and smoothed by 4 km using a PAEK smoothing algorithm. Contours for Peter I Øy were
incorporated from the Norwegian Polar Institute Data at 100 m intervals: 500 m intervals were extracted
and smoothed by 800 m, to match the appropriate resolution of the main contours.
All contours were merged together and lines <5 km in length were deleted. Further lines <20 km were
deleted in ‘non-mountainous’ regions, so as to avoid deleting small mountain peak contours but to still
simplify the main dataset. These regions were interpreted manually using the hillshade of the DEM used
to produce the contours.
