Hi Puneet,
From my experience you have to treat the text file as the datasource
and the (only) layer will have the same prefix. So don't point to
the folder, instead point to the file itself as the datasource.
Also, it seems ogr likes to have the CSV file with a .csv extension.
Even adding that CSV: prefix doesn't do the trick for me - so rename
your text file.
So here is what works for me:
$ cat foo.ovf
<OGRVRTDataSource>
<OGRVRTLayer name="foo">
<SrcDataSource>foo.csv</SrcDataSource>
<SrcLayer>foo</SrcLayer>
<GeometryField encoding="PointFromColumns" x="lon" y="lat"/>
<GeometryType>wkbPoint</GeometryType>
</OGRVRTLayer>
</OGRVRTDataSource>
$ cat foo.csv
"lat","lon"
54,124
55,122
Hope it helps,
Thanks, but unfortunately no. Here is my situation --
cd "C:\My Documents\resources"
less foo.ovf
<OGRVRTDataSource>
<OGRVRTLayer name="foo">
<SrcDataSource>"C:\\My Documents\\Data\\foo.csv"</SrcDataSource>
<SrcLayer>foo</SrcLayer>
<GeometryField encoding="PointFromColumns" x="LONGITUDE" y="LATITUDE"/>
<GeometryType>wkbPoint</GeometryType>
</OGRVRTLayer>
</OGRVRTDataSource>

I can't tell whether ogr2ogr can't file 'foo.ovf', or it can't find
the files referenced inside 'foo.ovf', or if I have something else
wrong altogether.
