Hi ByronThe answer is yes. Create your 2 grids using the vector to radtor tools within qgis or saga and then use grid calculator to obtain the difference between the two.Kirk SchmidtSent from my Galaxy -------- Original message --------From: Emma Hain via QGIS-User <qgis-user@lists.osgeo.org> Date: 2024-11-20 12:15 a.m. (GMT-04:00) To: Byron Veilleux <by...@conjugategeo.com> Cc: qgis-user@lists.osgeo.org Subject: Re: [Qgis-user] volume calculation workflow.
