[fdo-users] FDO 3.1 vs 3.2

[George McLean]

I just thought I would follow up with a fix for the unsupported geometry 
type error I was getting. This may already be well known but I thought 
someone might benefit from my experience. From what I can tell osgeo.fdo 
geometry types do not support Z or M in the definition of the geometry. 
I changed the dimensionality in the call to gf.CreatePoint from 2 which 
gave me XYZM to 0 which gave me XY. This also worked with the call to 
CreateLineString.
