I get some data with number of specimens with a request to interpolate it using kriging method.
After some investigation it appeared that kriging results (performed in ArcGIS Geostatistical Analyst with default parameters) are not satisfactory. Interpolated values are far different from measurements (especially top ones) and the surface doesn't look reliable. Here's the picture:
I suppose that the main problem is insufficient number of samples.
How many points should we use to get reliable results?
Or maybe kriging method is not appropriate for such diversed values?
