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.
