Comparing two surfaces

Can Pix4d take one surface from a drone and compare it to another surface to see how much volume was removed from a site? Right now I fly a quarry and process the photos to create a surface. I then return to the same site about a month later and fly the same area. I create another surface and then I compare the two surfaces in Civil3d to let the client know how much material was removed.

Hi @Scott_Hopkins ,

Welcome back to our community!

If you are talking about surface subtraction, it is unfortunately not available in PIX4Dmapper. I would recommend using QGIS or ArcGIS’s math function for raster calculation.

Have a good day!
