Paul,
for the coastline you can follow this example (in the Complex Shape section):
http://yapso.sourceforge.net/demo/demo.html

note that you don't need yapso to do it but you can find the file with
the coastline in the last version of yapso
http://downloads.sourceforge.net/yapso/yapso-0.3.4.tar.gz?download

you can also take a look at m_map
http://www.eos.ubc.ca/~rich/map.html
as far as I remember not every function works in octave but this might
have changed since the last time I tried.

Regards,
Claudio
