v41 computing volume from a DEM in ArcMap 

Thank you for the clear and concise video, very well explained!

Wonderful, love the concept of extracting volume.

Good job. . . . Thanks

Can I use 3D analyst tool --> Functional Surface --> surface Volume toolbox to find the volume? Thanks for your video lectures.

Well explained! How do I calculate the volume of a ditch or say a pond?

what if the reference plane is inclined?

But when the reference surface is NOT flat! But have a difficult terrain! That mean your surface contain hundreds or thousands of different heights How can i do that!?
