<div dir="ltr">Hi,
<div>I've got some data that is in VPF (Vector Product Format)
format and it appears that the OGDI vector should be able to
consume it.</div>
<div><br>
</div>
<div>I have GDAL 3.4.0 (the OSGeo4W build) and cannot figure out
how to even run "ogrinfo" on the data set. </div>
<div><br>
</div>
<div>From this page (<a href="https://gdal.org/drivers/vector/ogdi.html" target="_blank">https://gdal.org/drivers/vector/ogdi.html</a>),
it appears that the syntax should be <br>
</div>
<div><br>
</div>
<div>ogrinfo
gltp:[//<hostname>]/<driver_name>/<dataset_name>:<layer_name>:<family></div>
<div><br>
</div>
<div>but in all of the examples, the "driver_name" is "vrf" so I
tried that (as well as "vpf" out of desperation) but I'm on
Windows so I'm puzzled about the exact syntax.</div>
<div><br>
</div>
<div>My data is in d:\users\carl\vvod (which contains the dht
and lat files).</div>
<div><br>
</div>
<div>>ogrinfo gltp:/vrf/d/users/carl/vvod<br>
</div>

<div>There are indeed "cat" files in every sub-directory of
