Thank you for the information about trac, I didn't know this software, but it could be useful! I tried redoing the calculations without rounding. The results are closer to the results obtained with r.volume (only tens of meters of difference, instead of thousands‌), but they are not the exact

Hi I noticed you have a raster with a "minus" character in the name. Sometimes that gives trouble. Not sure if it's relevant to the current problem, but it might be worth renaming to something like "dec_juin" (underscore instead of '-') and trying again.   On

Hello, I tried using r.volume as you suggested. According to the documentation it is suitable for what I am trying to do. However, when I use it, I don't have the "Total volume" line at the end of the report, like it is shown in the documentation. I just have the total volume of each clump,
