      <IP_info>This is a polygon comprising easting and northing locations 
      tracing parts of the coastline at Dampier WA as well as a rectangular area inland.
      This is used to specifically set the onshore initial condition in a tsunami scenario
      and here, it is used with a unit test in test_polygon.py.
      
      The coastline was derived from Maritime Boundaries which is a public dataset. However,
      rumour has it that some of it was digitised from a Landgate supplied image.
      
      The origin and license issues are still undecided</IP_info>
