I got the height field tutorial to work for me. Now, how do I place an
object at a specific place in (on) the height field? Is there a way to
query for a x,z to find out what the value of the height field y is?

There is an article including macros and sample scenes at the WikiPOV:

I first tried the help button for trace. gosh that is a really helpless way
to find anything.
your DropOnSurface was spot on. Thanks for the direction.

First I searched on "trace" ... too many hits and I never found the right
reverence.
When I went to index tab, the trace entry was also just what I should have
found first.
Since my learning mechanism is based on creating and solving errors. I am
learning a lot.

If you are using winpov, just write "trace" on the editor (ie in the
pov-file you are editing) and press F1. It will take you directly to
the appropriate subsection.
