I am using ArcGIS Pro 3.0.0.

I have two multipolygons and I would like to interpolate the values of one polygon to the other. I found the Areal Interpolation tool which does exactly that. One of required option/argument is that the tool asks the user to choose the dataset type average, rate or event.

And, that's where I am stuck because the values are categorical ranging from 0-10.

What datatype should be selected for such an interpolation?

    Can you please reflect a bit more on your categories, what 0 or 10 mean?

  • @fatih_dur means 0 = Flood Factor (FF) is 0 and vice versa is true for 10. Aug 10 at 12:55
  • I'd use average and just convert/round the results to the nearest integer category

  • @Brennan, average won't work since the values are categorical. 2 days ago
  • If the categories map linearly to whatever is it they measure, why not just treat them as integers, average them, then round the result to the nearest integer? If the categories are not along a linear spectrum, like land use classes, I'm not sure how you'd do any sort of interpolation, as opposed to just taking the dominant class in a given polygon.
