Chaitanya, <br>

Same result with 1.8.0<br>
With some effort we can test with 1.9, as we have not found any
OGDI-compiled OGR for 1.9<br>
Then also I assume we can insert debug-flags to maybe get more
information. We have experimented with the Java bindings (jar) as we
will integrate OGR with a Java servlet.<br>
<br>
Best Regards<br>

Could you first test your data with the latest version of GDAL?
The latest Windows binaries can be obtained through the OSGeo4W
installer.<br>
<br>
In any case, I couldn't find any reference to DNC in the OGDI
library, which is used by OGR to read VPF files.<br>

I cannot make OGR work with VPF DNC data.<br>
ogrinfo and ogr2ogr crashes when trying to read data from any
level inside the VPF structure. DHT and LAT files do exist.<br>
OGR does work for standard VMAP0 and VMAP1 data.<br>
Is this a known limitation?<br>
Does DNC require some special syntax?<br>
I have used e.g. ogrinfo gltp:/vrf/C:\xxx and ogrinfo
gltp:/vrf/C:/xxx<br>
<br>
Tested version:<br>
1.7.0b2 as included in FWTools 2.4.7 on Windows<br>
<br>
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.<br>
