[Mapserver-users] Spatial/geometric extent of DGN?

[Twan Kogels]

Vincent,

Thanks for the usefull reply! I just tryed your suggestion and it works, 
but the -so option was not known. It appears it's introduced in gdal 1.1.9 
and i was using 1.1.8. No problem, i've downloaded/installed the 
1.1.9  version and the -so option is now known. I tested it on a DGN file 
and the Extent: is printed. Now i'm gonna try to get the dgn to work with 
mapserver.

The given link is a handy link, i've bookmarked it.

Best regards,
Twan
