HI Folks,
Thanks for all the responses. I think at this point the visualisation
problem is more one of not really know what client we're going to use (I'm
struggling to find any good, easy to use, Open Source 3D clients). So I'll
forgo the visualisation aspect for now.
I guess I'll just turn it into a WMS heightmap to start with
@Phil, that sounds interesting, I'll have to give it a try.
@Marcus - the web-app you demo'd is interesting. It also kind of works in
Opera (though you have to out of your way to enable webGL; seems to be off
by default). Nasa WorldWind can do similar things, though that's Java.
Thanks all,
Jonathan
