[Vis5d-users] Re: Underwater Topo

Hi

I tried the modifications suggested.
however the topo layer is still at the 0.0 level (sea level)
I still cannot have the underwater relief shown
(I only see the 2-d colored image at the top)
does it mean that I had to code my underwater topo data's baselevel as level
0.0???
and the various depth converted to "height" from this baselevel???

Thank You

GT
