I think that if the counts are representative for a spatial support (area) or temporal support that does not vary, then you can consider the counts as an unscaled density and can interpolate. If they are representative for varying spatial/temporal support, I would avoid it, and first work towar

[R-sig-Geo] Interpolating Count Data?

All, I am reviewing some research in which a number of interpolations (Inverse Distance Weighting) were done on Species Abundance and Taxa Richness. My gut and my memory suggest that interpolating count data is not acceptable. After several hours of research I couldn't confirm this. My questio
