I created a shapefile in ArcMap with 5 objects.  The first two are
really a collection of many line strings that I copied from a Census
Tigerline file and the other three I created using the ArcMap editor arc
tool.  The attached file shows what the shapes look like.

 

I can read the two smaller objects using OGR without any problem.  They
have reasonable point counts and the X/Y data from the ones I looked at
in the debugger look valid.

 

I can not get to the point data in the larger three shapes.  The
geometry type shows up as linestrings but the point counts are way to
low (i.e 28, 10 and 3).

 

I tried to cast them into OGRCurve, OGRMultiLineString,
GeometryCollection and a few more I think but none of them worked.

 

Is there some special way to read data like this?
