Need for better nautical charts

[Archive1]

We need better nautical charts that make available at least some sense of depth. Perhaps just a contour delimiting the 100 meter line along coastlines, but it would be nice to have some idea re: depths in shallower water without having to ping (sometimes in dangerous conditions). I am sure the Uboat commanders had nautical charts with at least minimal depth information. The nav map available is terribly insufficient (in many ways) and quite crude - devoid as we know of depth information except for faint coloration differences. Anybody know of a source of reasonably large scale maps that could be edited digitally with depth soundings (and free in the public domain, of course)? I've tried several sources but cannot find same. I realize the Lat/Long limitations of SH3 regarding real world azimuths, but coastlines would be reasonable accurate and congruent with the game. Perhaps someone could make a high quality scan of a representative coastline (East coast of England, West coast of Norway, for example) and we could add sounding data to it digitally, then upload it to the community as a test? The charts, as hardcopy, could reside outside the game, ie, not be accessed by some keystroke, to keep it simple.
Am using GWX v2 - great work, guys!
