[GRASS-user] compare a DCELL and FCELL question

[ming han]

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
Ming

The error means the number of raster maps in the development parameter does
not match the number of years in the observed_population CSV. So for
example, if you specify development=urban_2001,urban_2006,urban_2011 (3
maps) then the observed_population file should look like this (header + 3
lines):

year,37037,37063,...
2001,19860,10980,...
2006,20760,12660,...
2011,21070,13090,...

If you can't see any obvious mistake with your data, I would have to see
the r.futures.demand command you are trying to execute and the input CSV
file.

Re: [GRASS-user] GRASS won’t open after locking up

[Maris Nartiss]

1) Clean up ".tmp" directory located inside the last used mapset;
2) Remove the "~/.grass7/rc" file to force a clean start for GRASS. It
is safe as GRASS will generate a new one if rc file is missing.

Hope this helps,
Māris.
