question about volume attribute

JSL Global Mapper UserTrusted User

When measuring volume between two surfaces, what is the meaning of the "AVG_Z_DELTA" attribute that results from the process? Is that the mean thickness?

    Yes, the volume calculation takes a large number of samples from each surface. The AVG_Z_DELTA would be the average of the difference in Z values, or average thickness.
