[Qgis-user] batch conversion of raster file to GeoTIFF format

[Ramon Andiñach]

Hi Leo,

I can't help you with why it isn't working as a batch, but:

1. Yes, the GDAL script at the bottom of the window should be expected to work in the OSGeo shell. 

2. There's probably an equivalent in Processing, which might give you a better response.

I tried using the GDAL Translate option in the Processing Toolbox but it reads only the *.hdr file of my raster not the file that holds my raster data. When I execute the batch process file using file.hdr as my input it returns:
