I think you're saying that your input data would be a 2-dimensional
array each element of which would indicate an height above sea level
for that X,Y coordinate (the more I read your original question the
more I doubt my assumption but here goes anyway).

Firstly if you can mangle your data into some format which would be
acceptable as format I suspect that this ...

... might do that job.

Assuming that you can't do the mangling (I know I couldn't) have you
seen this ...

... I suspect however that you wanted some output that looked, however
roughly, like an aerial photograph - would be interested to know. I
live in a hilly, rather attractive city and have long wondered about
the possibility of being able to build a model of the land in
software.

Sorry this isn't more help. Maybe you could expand on your needs a
little ?
