[Qgis-developer] Volume between two surfaces

[Pedro Venâncio]

Hi all,

Is there any way to calculate the volume between two surfaces (two DEM rasters)?

There are ways to calculate the volume between a surface and a particular height value (GRASS r.volume or SAGA Grid Volume) but I can not find how to calculate the volumes (landfill / excavation) between two DEM.

Any tips?

Thank you very much!

Best regards,
Pedro Venâncio
