Sounds great, but if it ends up like the UN Atlas of the oceans it will be
just another nearly useless "webstacle" that provides images and no access
to the real data.
Perhaps listers could respectfully write and suggest that they provide links
to downloadable GIS data in some reasonable form, such as shapefiles, to
allow people to actually use the maps in significant ways?
Cheers,
Dimitri
