gdal - gdal_grid problem reading vrt file

I am trying to parse csv file and visualize it as geotiff using gdal_grid but I keep getting this error:

C:\work\testgdal1>gdal_grid -ot Float32 -l test  test.vrt dona.tif
ERROR 1: Failed to open datasource `test.csv'.
Unable to open input datasource "test.vrt".  

Failed to open datasource `test.csv'.

Both test.csv and test.vrt are in the same folder.

What can possibly go wrong and how to fix it?

Environment:

Windows 7 x64
osgeo4w as of 2 May 2011

test.vrt

    
    test.csv        
    test
    WGS84

Answer

Ah yes, I feel slightly to blame for this... I've just re-read the page on OGR's handling of CSV and it says that it only accepts commas, semi-colons, and tabs as field delimiters, but your file is fixed-width.

What you will need to do is convert each run of spaces to a comma. In Linux you can use a sed script, but as you're in Windows your options are a bit more limited. A simple way would be to load the ASCII file into a spreadsheet program, telling it to use fixed-width fields, then save it out telling it to use commas as separators. Not ideal, I grant you, but it is a technique I've used in the past.
