[GRASS-user] How to sum a hundred of raster maps using r.mapcalc

[Miguel Carrero]

Hi all, 


Thanks to everyone for the help. I’ve tried with g.list, and pass a file with all map names in r.mapcalp, but realised that there is a limit on space to sum a high number of maps at the same time. So, I’m going to have a look to r.series.

Cheers, 

Miguel.

Hello,

Interesting, I always used mapcalc for this. Do you know what are the
advantages of using r.series instead of mapcalc for this type of job?
