[GRASS-user] Use of vmap0 data

[Roger Mason]

Hello,

I'm trying to make use of the vmap0 data, following the article from
Markus Neteler in Grass News 3 (2005).  I recompiled gdal to include
the OGDI driver and went through the process of changing the directory
and file names as explained in the article.  However,  am unable to
open the files:

GRASS 6.2.1 (vmap0nad83):~ > ogrinfo -ro -summary gltp:${MYDISK}
'polbnda at bnd(*)area'
FAILURE:
Unable to open datasource
`gltp:/vrf//home/rmason/Download/vmap0//v0sas/vmaplv0/sasus' with the
following drivers.
  -> GRASS
  -> ESRI Shapefile
  -> MapInfo File
  -> UK .NTF
  -> SDTS
  -> TIGER
  -> S57
  -> DGN
  -> VRT
  -> REC
  -> Memory
  -> BNA
  -> CSV
  -> GML
  -> GPX
  -> KML
  -> GeoJSON
  -> GMT
  -> SQLite
  -> ODBC
  -> PGeo
  -> OGDI
  -> PostgreSQL
  -> AVCBin

If someone can suggest how to debug this I'd be most grateful.

Thanks,
Roger
