True. I didn't think about that. I guess that solves the issue for you
Chip, unless you need access to the Z values in MapScript in which case
we would have to add a 'z' value to the pointObj and modify mapogr.cpp
to set the z value. With the current version if you access a 3D
shapefile with OGR the Z values are simply dropped.
