Yep. I just figured out the same a few minutes ago & fixed it in CVS.
(+6.2 release branch). It was ok in 6.1.0.


So ps.map is pretty much broken in 6.2.0. Bummer.



If we can figure out why NVIZ volumes are broken and fix the following
bug, I'd vote for a quick 6.2.1 release.

NVIZ volume problem (test with slovakia3d dataset) - sometimes it works
 * fails from command line; ok if the volume added within NVIZ (bug #4725)

It would be nice to fix this one too:
