Tusentakk Håvard, that works fine!
But still wondering why GRASS can reclass a 0=NULL, but not a NULL=0...

You could use the GRASS function r.null (available in
Processing).

I'd like to reclass a raster that contains just cells with values nodata

Now I want to change all nodata values to 0, but I cannot find any way
to do this. I tried the grass and gdal tools and the qgis raster
calculator, but without luck.
Does anyone know?
Thanks!
Raymond
PS
In fact I have 2 of these layers and I want to "union" them. So I tried:
raster1 OR raster2
in the calculator, but that only returns 1 for the cells that contain a
1 in both input rasters, resulting in the overlapping area.
By changing nodata to 0, I'm hoping to calculate:
(raster1 + raster2) ^ 0
and get my desired results.
Any ideas on this?
