Christoph,
It looks like all three methods are working as they should.
In the first one, the ogr2ogr converts it to two dimensions,.
In the second one, the shapefile driver does that.
In the third method you are getting the geometry type, which is in wkb
format. I would guess them to contain the

Okay, sorry, I will describe it with more detail.
I have a shape file where ogrinfo reports it is a "Geometry: 3D Line String".
Selon Christoph Dohmen :
You're not very explicit about what you want to do. From the tile, I guess you
want to get rid of the Z coordinate of the geometry to produce 2D only
geometries ?
If so, you need to specify '-nlt LINESTRING' (remove the 25D otherwise you'll
still get the Z coordinate) or
Hi list,
I have a set of shape files which are reported as 'Geometry: 3D Line String'.
The geometries
are all LINESTRING, but they have 3D coordinates. Playing around with ogr2ogr
and different
options like '-nlt LINESTRING25D' or '-dsco "SHPT=LINESTRING25D"' did not bring
the expected
results.
