Bug report #14165

Updated by Paolo Cavallini over 3 years ago

I'm getting:



Failed to create the output layer: non riesco a creare il layer (errore

OGR:Geometry type of `Unrecognised: 1003' not supported in shapefiles.

Type can be overridden with a layer creation option

of SHPT=POINT/ARC/POLYGON/MULTIPOINT/POINTZ/ARCZ/POLYGONZ/MULTIPOINTZ.

)



Note from Even Rouault:

Yes, it seems than any 3D geometry outputted by this plugin will not be GDAL

1.X compatible. 2D geometries should be OK though.

Perhaps there's somewhere in QGIS code base a way of converting ISO WKB to

old-style WKB ?
