There was a discussion on IRC about whether to upload PGS coastline
data "as-is", or to try and correct the 10-30m shift that it appears to have
relative to some other datasets.

Any views on this? Shifting the data will require us to justify how we
calculated the error (e.g. several of the screenshots people have given me
seem to be from google maps) and preferably we need a model for the error
which is consistant worldwide.

p.s. how's Sydney harbour correlating with other data?
p.p.s. did anyone email NGA to ask?
