Dear STEP forum,
I am trying to create a tiff image from a coh_sigmaAvrg_IW_VV_11Sep2018_23Sep2018_Coh_Ampl.tif with image profile:
#RGB-Image Profile
#Fri Mar 23 16:46:55 CET 2018
blue=0
name=coh_sigmaAvg_null
green=if fneq(coh_VV_11Sep2018_23Sep2018,0) then max(min(floor(sigmaAverage*12.7+191.5),255),1) else 0
red=if fneq(coh_VV_11Sep2018_23Sep2018,0) then max(min(floor(coh_VV_11Sep2018_23Sep2018*256.565656566-1.56565656566),255),1) else 0
I call p convert with this command:
pconvert -f tif -p coh_sigmaAvg_null.rgb -s 0,0 -o /output/coh_sigmaAvrg_IW_VV_11Sep2018_23Sep2018_Coh_Ampl.tif
This works fine when pixelspacing of the input image is set to 30 meter, but when it is set to 15 meter unfortunately it crashes with this error message:
reading file coh_sigmaAvrg_IW_VV_11Sep2018_23Sep2018_Coh_Ampl.tif

error: failed to create image: null
The size of the input image is 6,8 GB.
Could you please advice me how to fix my issue?
Thanks in advance,
Thijs
