[gdal-dev] GDAL 2.1 and Norwegian SOSI

[Blumentrath, Stefan]

Hei again,

First of all, now the SOSI file opens fine again. So, many thanks for that!

Unfortunately, I now get a new error on ogrinfo ./ADM_kommune_0620_Hol.sos lines

Layer name: lines 
Geometry: Line String 
ERROR 4: Unrecognized geometry of type 5. 
ERROR 1: Feature 82 referenced by 2204, but it was not initialized. 
Aborted (core dumped)

I get it for polygons too. Geometries of type 5 are curved geometries which got introduced in SOSI version 4.5 - if I am not mistaken...

Geometry type 5 (BUEP) is defined in https://github.com/kartverket/fyba/blob/master/src/FYBA/fyba.h (Line 408)... Would it be sufficient to add something like:
        case wkbCompoundCurve: {
            pszSosi = ".BUEP";
            break;
        }
to: ogr/ogrsf_frmts/sosi/ogrsosilayer.cpp (not sure if the translation is 100% correct)

But maybe also trunk/gdal/ogr/ogrsf_frmts/sosi/ogrsosidatasource.cpp needs modification...?
(I am no programmer).

Seems to be an older issue and other GeometryTypes seem to cause trouble too:

Cheers,

Hum, I see this is actually a 2.1.0 regression.
Fix available in https://trac.osgeo.org/gdal/ticket/6500
