No, but I'm not sure that would be more accurate in any sense.
The cell values I usually see represent some field values integrated over the volume of the cell. In this case, the smaller the cell volume, the more representative the integrated value is likely to be for any point in the cell. Thus, if I was to introduce weighting, I would use the inverse of the cell volume. I'm sure you can quickly come up with a counterexample why scaling by the cell volume is the right thing to do. And that's kind of the point. The conversion from cell data to point data is ambiguously defined and the best solution depends on your data semantics and problem domain. Although simple averaging is not always ideal, it is fast and can be used as a low order approximation as well as anything else. -Ken On 10/18/11 8:45 AM, "Stephen Wornom" <[email protected]> wrote: >Moreland, Kenneth wrote: >> None of those.
