Hi,

Hopefully this is a really stupid question.  I can't seem to locate any 
layers using ogrinfo:

$ ogrinfo gltp:/vrf/home/<snip>/Global_Map/Area
ERROR 4: OGDI Driver doesn't support update.
Had to open data source read-only.
INFO: Open of 
`gltp:/vrf/home/gdata/auslig/Global1M/Global_Map_Data_Australia_1M_2001/Vector/VPF/Australia/Global_Map/Area'
using driver `OGDI' successful.

http://gdal.velocet.ca/projects/opengis/ogrhtml/ogr_utilities and 
drv_ogdi.html indicate that this should "report a list of available 
layers (and their layerwide geometry type)".

Attached is the output from:
$ ogdi_info -u gltp:/vrf/home/<snip>/Global_Map/Area

I'm just learning about the VPF format, however from this output I 
gather that I should have the following coverages:

Coverage_name: tileref
Description: Tile Reference
Level: 3

Coverage_name: bnd
Description: Boundaries
Level: 3

Coverage_name: hydro
Description: Hydrography
Level: 3

Coverage_name: pop
Description: Population
Level: 3

Coverage_name: trans
Description: Transportation
Level: 3

Any ideas/recommendations?  FWIW, ArcGIS 8.1 only seemed to recognize a 
"tileref" layer, not the others....

cheers,
John
