Hello
About 20,000,000 cells. That should be OK.
Do you know how many different values are actually in the
data?
Yes... In this case is 6608. In other examples it can be
3000 or 2000. Why?
Just to understand how complex the calculation of r.mode has to be.
I'd try two things here. First can you change to a smaller
region and
rerun r.mode and try to display the results?
Yes. It worked with a much smaller image.
Ah, good.
Second: the result of r.mode is a "reclass" of the
original values. So
I suppose it has to be recalculated each time you want to
display. You
can make that reclass map into a permanent raster by
running:
r.mapcalc "output2 = output1"
I tried this and after 15 minutes running I gave up. Can
this be related with memory restrictions?
Well, that's not good. Yes, maybe a problem with disk space or
memory? l'll have to leave to someone more knowledgeable to answer
here.
If you just let it run for longer will it finish?
