Question.
When using the analyze volumes tool, the resulting quantity between two terrains should be the same as the quantity as a delta terrain built from the same surfaces and analyze volumes performed against a plane elevation 0.00'. But, it is not.
We have a project with the following results comparing existing to proposed (analyze volumes).
Cut Factor = 1.0000
Fill Factor = 1.0000
Cut = 6254773.6620 sf3
Fill = 4400699.4384 sf3
Balance = -1854074.2236 sf3 = 68,669.42 cy
We then generated a delta terrain between the same terrains, then used analyze volumes terrain to plane of 0.00 and had the following results.
Cut = 6255136.0495 sf3
Fill = 4405001.8043 sf3
Balance = -1850134.2452 sf3
We get the same result regardless of using boundaries. Could someone try to explain.
So.... What I'm saying is that there is an apparent problem with the results of the analyze volume tool. That's kind of a big deal.
