Re[fdo-users] turn geometries

[Maksim Sestic]

Does SHP support MultiPoint geometries at all?

Sorry, I don't really understand this. A point with multiple positions?!

Well, there is only one geometry returned.  So for example, if I step
through the program (using C#.net) the point shapefile I referred to returns
the following from the CreateGeometryFromFgf:

"Point(-116.925 44.058)" for the text.  This should be something like
"Point(-116.925 44.058, -116.xxx 44.xxx......)"
