[GRASS-user] calculate the volume of a DEM with r.volume

[marion-brunet at sfr.fr]

<span style="font-family:arial,helvetica,sans-serif; font-size:12px">Hello,<br>
<br>
I tried using r.volume as you suggested.  According to the documentation it is suitable for what I am trying to do.<br>
<br>
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, but not of all the clumps... Has it ever happened to you when using this command? in the command line<br>
<br>
I simply wrote</span>r.volume input=difference clump=clump <span style="font-family:arial,helvetica,sans-serif; font-size:12px">in the command line<br>
<br>
Thank you very much,<br>
Marion</span>

I wonder if<br>
https://grass.osgeo.org/grass74/manuals/r.volume.html<br>
could be of any use here?<br>
