Thinking and reading more it seems I might be wrong in part. I assumed
OGR's DGN driver would ignore the georeferencing completely. It might
be that it does not; it might only ignore the projection metadata,
while it would recognize the coordinates of DGN vector features
properly. If the latter would be the case, v.transform after v.in.ogr
should be not necesary. Please somebody who knows speak up.


Pawan,

Does

g.region vect=your_imported_DGN
d.vect your_imported_DGN

work as expected? What is the output of

g.region vect=your_imported_DGN -g

?

Sorry for so many doubts, but I don't have any DGNs to check it out myself.

Maciek
