[gdal-dev] OGR support for VPF DNC?

[Andreas Oxenstierna]

I cannot make OGR work with VPF DNC data.
ogrinfo and ogr2ogr crashes when trying to read data from any level 
inside the VPF structure. DHT and LAT files do exist.
OGR does work for standard VMAP0 and VMAP1 data.
Is this a known limitation?
Does DNC require some special syntax?
I have used e.g. ogrinfo gltp:/vrf/C:\xxx and ogrinfo gltp:/vrf/C:/xxx

Tested version:
1.7.0b2 as included in FWTools 2.4.7 on Windows

I noted that only FME seems to be able to always correctly read the DNC 
data we have available. For example vpfview, nimamuse and ArcGIS do have 
various issues.

Best Regards
