Hi Emilio.
One basemap that might be useful is to use grdtrack to sample a profile of the
terrain, and draw this as the top of the basemap.
It may be easiest to have your depth map use either the NS or EW axis as the X
value on your plot, and the Z value as your Y. The profile you plot as the land
surface would therefore be EW or NS.
While Geoserver "would like" the coordinates to map to a coordinate system,
they don't need to in this case.
A left field approach would be to draw the images with a tool like GMT via CGI
scripts (does this very nicely) and not use Geoserver at all.
Cheers,
Brent Wood

Hi Emilio,
That looks really interesting. My question would be - do you actually need a
"basemap" to differentiate depths? You're using colour very effectively. If you
also used shape too (to help the colourblind - ideally when styling you should
never rely solely on colour), then it'd be very easy to visually see the
different depth groupings (although it already is to be fair).
How are you getting the depths to show? Is that actually using a height
component that GeoServer can render at an oblique (90 degree) angle? Or is it a
simple X/Y grid-coorg system? In the later case, couldn't you create a
shapefile or something similar in the same grid system and use that as the
basemap?
Regards,
Jonathan
