[OSM-newbies] National park boundaries

[swanilli]

Thank you.

Here is a sample:
http://www.openstreetmap.org/?lat=-34.07168&lon=151.10088&zoom=15&layers=B000FTF

The multipolygon annotated "Based on Australian Bureau of Statistics
data" I take to be accurate becaouse f its detail and coming from a
government source. The coastline in this area (htough not everywhere)
should be identical to it. The multypolygon named "Royal National
Park" is mostly identical to it, except that there are a few regions
of private property that have been excluded from it. I have been
identifying these from aerial imagery and the Australian Bureau of
Statistics boundaries.
