I recently saw some messages from someone looking for contouring.mbx.
I wonder if someone has used both surfer (with the MI interface) and VM
and could give us some hints on their respective comparative advantages.

Personnaly I use VM and find the interface (version 2.0) quite OK, but
the interpolation algorithms yield surprising results : when
transforming contour lines (say elevation 1,2,3,... to 10) into points
and creating a grid surface based on these points, the cell values
distribution is incredibly "SPIKY", with huge concentrations of cell
values around integer values (while we could expect a smooth
distribution from regularly spaced contour lines).

I tried to get some feedback from NorthwoodGeo on that matter and it's
good to know that they let three of my Emails unanswered. They,
apparently, are not very concerned with their customers and/or unabled
to give comment or (or dismiss) possible flaws of their products.

As anyone observed or understood the "spikes" ?
