[gdal-dev] OGR support for VPF DNC?

[Andreas Oxenstierna]

Chaitanya,

Same result with 1.8.0
With some effort we can test with 1.9, as we have not found any 
OGDI-compiled OGR for 1.9
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.

Best Regards

Andreas
