MI-L region to grd (difference in values)

[Simon H�bert]

I created a grd file in VM with a layer of regions with wind speed values
and I have difference with these values and my original vectoriel values.
It�s not big differences but enough to affect my results. I don�t understand
why these differences. Do you think that it would be better if I try an
interpolation with my region centroid points?
