difference plot including total volume

francescarusso

Hi all,

does anyone know if I would be able to accurately calculate a difference plot (including total volumes) in ArcGIS if I were to request the DTM of the in-survey and the DTM of the out-survey of a dredging volume calculation?

I have ArcGIS 10.2.2 with ONLY Spatial Analyst extension.

If it is possible, any suggestion how to d it?

Many thanks,

F.

differences are easy to determine in SA, what specifically are you referring to since there is no difference plot tool

EDIT

You wouldn't be referring to the Minus Tool to produce a map of the differences before and after would you?

Your volume estimates would be as accurate as the difference can be represented and the smaller the cell size the better.  Volume would be the differences in the cell counts * the cell area
