Hillshade and bathymetry compilation of Antarctica and the Southern Ocean, south of 50°S. Created by the Mapping and Geographic Information Centre, British Antarctic Survey.
Source data is reviewed and updated every 6-12 months to ensure coastline is up to date, and data sources are appropriate. Available as an Esri Tile Service. The tile layer can be used up to 1:110,000 scale.
Projection: WGS84 Antarctic Polar Stereographic, EPSG 3031

Lineage Statement
Datasets were prepared using ArcGIS Pro v3.5 and published to ArcGIS Online as an Esri Tile Service. A hillshade of the Antarctic topography was generated using the Antarctic DEM, with a z factor of 4 and displayed with a brightness enhancement of +15. The Extract By Mask tool was then used to clip the hillshaded DEM by the Antarctic coastline polygon dataset, to ensure the extent exactly matched the coastline.
A hillshade of the Sub-Antarctic islands and South America was generated using the GLO90 DEM, with a z factor of 1. This was clipped by the sub-antarctic coastline polygon dataset.
A hillshade of the bathymetry was generated using a z factor of 6. This was displayed with a transparency of 30%. Another copy of the bathymetry was styled using a blue to white based on depth, and displayed with a transparency of 20% and placed on top of the hillshade in the layer ordering.
