Chris,
Here is what the ogr docs say. Look in the directory structure of the VPF
to see what layer names and family names you have:
gltp:[//<hostname>]/<driver_name>/<dataset_name>:<layer_name>:<family>
Where <layer_name> is the OGDI Layer name, and <family> is one of: "line",
"area", "point", or "text".
Usage example 'ogrinfo':
ogrinfo gltp:/vrf/usr4/mpp1/v0eur/vmaplv0/eurnasia 'watrc...@hydro(*)_line'
In the dataset name 'gltp:/vrf/usr4/mpp1/v0eur/vmaplv0/eurnasia' the
gltp:/vrf part is not really in the filesystem, but has to be added. The VPF
data was at /usr4/mpp1/v0eur/. The 'eurnasia' directory should be at the
same level as the dht. and lat. files. The 'hydro' reference is a
subdirectory of 'eurnasia/' where watrcrsl.* is found.
Usage examples VMAP0 to SHAPE conversion with 'ogr2ogr':
ogr2ogr watrcrsl.shp gltp:/vrf/usr4/mpp1/v0eur/vmaplv0/eurnasia
'watrc...@hydro(*)_line'
ogr2ogr polbnda.shp gltp:/vrf/usr4/mpp1/v0eur/vmaplv0/eurnasia
'polb...@bnd(*)_area'
An OGR SQL query against a VMAP dataset. Again, note the careful quoting of
the layer name.
ogrinfo -ro gltp:/vrf/usr4/mpp1/v0noa/vmaplv0/noamer \
-sql 'select * from "polb...@bnd(*)_line" where use=26'

well, orginfo tells me:
FAILURE:

OGDI is in there -- so I assume that it's built in -- how else can I tell?
thanks,
