I have a GeoTIFF file (real32) with one band(0)
Like to extract just the value 0.4 from it.
But whatever I try, nothing works out.
It's so simple, but I can't see it....
With the RasterExpressionEvaluator I use this expression:
@if(AA0]==0.4,0.4,0)
The only result I get is : 0
Probably because the band only contains RGB values whereas the z-value 0.4 is interpreted? But what then, is the best way to extract this?
