[GRASS-dev] i.fusion.hpf addon: observing strong range change

[Markus Neteler]

Hi,

I am using i.fusion.hpf on Worldview-2 data and see that the resulting
range is completely different:

# orig
r.info -r wv2_17OCT08182034_M2AS_058891334010_01_P001.5
min=0
max=1509

# HPF
r.info -r wv2_17OCT08182034_M2AS_058891334010_01_P001.5.hpf
min=-1045.79783524995
max=3416.06793724612

Is that intentional?

thanks,
Markus
