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

[twan@twansoft.com (Twan Kogels)]

Hello,

I've received a couple of DGN files orginal made in Microstation. I ran 
"ogrinfo" (a program supplied with gdal) on a single dgn and it output was:

========
using driver `DGN' successful.
1: elements
========

So i guess gdal can read the dgn file. But now i want mapserver to display 
the DGN files. So i made a .map file and got stuck when defining the EXTENT 
part of the map file, cause i don't know it.

When using ESRI shapefile, a program named "shpinfo" gives me the 
spatial/geometric extent of a shapefile which i then use in the .map file.

Is there a program (for *nix) which gives me the spatial/geometric extent 
of a DGN file?

Best regards,
