[Qgis-user] QGIS1.5 on Win (standalone installation): Problem with VRT

[Agustin Lobo]

Hi!

I use the gdal utilities (raster/Build Virtual Raster) with 4 files but
then QGIS sees one band only (only one band listed in the Properties dialog).
This is the VRT file, could anyone tell me if this is correct?
