     <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.
+    roughly tracing parts of the coastline at Dampier WA as well as a small 
+    arbitrary area inland.
     
-    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 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 origin and license issues are still undecided</IP_info>
+    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.
