I have been asked to model an Ocean by a 3rd party in terms of the
possible movement patterns fo ships, has anybody got any suggestion on
where to start on this issue?

I am used to think about cost distance models, friction maps, nearest
neighbour etc on land.  But an ocean is a different concept. Its a fluid
mass which can change density.

In terms of sailing its going to have areas such as sandbank, rocks,
shipwreck sites etc which in terms of land movment patterns can be
classified as inpassible areas,  openwater as flat land masses.

Has anybody tried to do anything simalir?, any suggestions hints etc,
greatly appreciated.
