[Gdal-dev] Wrong geometry type detected

[Chapman, Martin]

If that doesn't work just call flattenTo2D() before using the geometry
and that will make sure it's 2D.

Petteri,

There was a major overhaul of OGR geometry in the
early fall of 2005 to carry along coordinate dimension
information explicitly.   That overhaul should fix the particular
problem you are seeing.

I would encourage you to upgrad eto GDAL 1.3.1.

Best regards,
