Really excellent render!!
Like you say, bathymetric data is missing, unfortunately. I have been
looking everywhere for that, but it is not readily available on the net, it
seems, except for some more or less detailed maps. In any case, bathymetry
for coastal regions would then still be a problem, at least till about the
20m depth contour, as ships rarily go there for measurements. However, there
must be satellite data somewhere. Not made public for strategic reasons? I
wonder.
