I wouldn't necessarily rule out iso-surfaces, but it sounds as though you need a
height-field.

With an iso-surface, it will largely depend on how much control you need.

Also, iirc you can combine a hf and an iso. Put the general terrain topology in
the hf, but then give some attractive detail with the iso-function?
