Hi, I am hoping someone can help.
I am trying to extract areas "fill" volumes from a DEM using global mapper to use in drainage modelling software.
I have followed the procedure for calculating cut/fill for an area shape. This appears to have calculated the fill/cut volumes ok, but the fill areas don't appear to have calculated properly (eg: 0.00008 sq m - is not correct). See attached screenshot / image.

Unfortunately the modelling software program that I am extracting this information for requires areas at different levels rather than volume.
Can anyone suggest what I am doing wrong.
