Hi Markus and Micha
I am just trying to find grids have the same values in these two
rasters, I will try the threshold approach.
Thanks
Ming

I can see that the maximum values are different. Have a look at the
Range values.
What are you trying to do? Maybe there's a simpler approach...

Many thanks for your reply.
Here is the command I am using:
if(float(cat1_acc_riv) == float(cat1_minacc), str_r, null())
The str_r is a CELL raster. the result is different when I change it
to:
if(int(cat1_acc_riv) == int(cat1_minacc), str_r, null())
Is there some reason that you expect the rasters to be the same? Maybe
begin by posting the outputs of `r.info` for both rasters, and what
command you used to compare them?

Hi Everyone
I tried to compare if grids in two rasters are the same, one raster is
FCELL and another raster is DCELL. I got different result when I int both
raster first before comparing them; and when I float() both raster first
before I comparing them
Is there any reason for this?
Thanks
