Abstract:
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.
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 100m interval contours for land south of 60°S, generated from REMA v1.1 and other sources.

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 3x3 cell size.
100 m contours were extracted and all contours with a height <1m were deleted, as well as erroneous
offshore contours. All contour ‘dangles’ were identified and then fixed to create a continuous dataset.
They were fixed either by interpreting the correct line from satellite imagery or from ‘Copernicus
WorldDEM 90m’ contours. Such lines are attributed with ‘interpreted’ in the source field and should be
treated with caution. In other locations where the contours significantly overlapped the coastline,
contours were redrawn/interpreted to not go offshore. 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 300 m using a PAEK smoothing algorithm.
Contours for Peter I Øy were incorporated from the Norwegian Polar Institute Data at 100 m intervals.
The source of every line is written in the attribute table.
All contours were merged together and lines <150 m in length were deleted. Further lines <1500 m 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.
