I'd like to use  the isosurface feature by using an image_map as a
'normal'  to get a height_field on a sphere.

I have been looking for 2 map of the world : One for the shape of the
oceans and continents, the other is for the function to deform the
sphere. So far no success. I got a lot of 'DEM' sites and maps with a
lot of prints on them, but none with nothing but geographical pictures
on them.

Does anyone know where I could get high resolutions maps of the pictures
I enclosed ? I got these from a CD.

Thanks

Fabien
