In 2013 a hillshade image was produced from the 2011 digital elevation model. The hillshade was created in ArcMap using the 'hillshade' tool with an azmith of 315, an altitude of 45 and a vertical exaggeration of 5. The hillshade covers the full extent of Christmas Island. The hillshade image can be viewed as a greyscale image, or underneath the DEM (if semi-transparent). It can also be viewed under any other layer to show the lie of the land, for example orthophotography, canopy heights or infrastructure.
The hillshade was created from the 2011 DEM which is vertically accurate to 15cm and horizontally accurate to 30cm.
