Ole Nielsen mainland_only.csv 556538090 Yes Ole Nielsen Geoscience Australia Geoscience Australia This is a polygon comprising easting and northing locations roughly tracing parts of the coastline at Dampier WA as well as a small arbitrary area inland. The data was obtained by subsampling the digitized coastline by a factor of 10 making it a very rough approximation. It is used with a unit test in test_polygon.py as an example of a convoluted polygon to test the functionality in ANUGA to specifically set the onshore initial condition in a tsunami scenario. The original coastline was derived from Maritime Boundaries which is a public dataset but some of it was modified using a digitised coastline from a Landgate supplied image. However, after decimation, this dataset is obscured and does not provide a usable coastline. As such it does not infringe on Landgate's IP.
