I have data for some countries but not for others and would like to predict the missing values from neighboring countries weighted by their area, distance etc.
To do so, I am using the
geostatistical wizard to interpolate information between polygons. Since I have not even succeeded in implementing areal interpolation using the ArcGIS interface, I did not dare to use ArcPy which is why I cannot provide you with any code. Here is what I did:
I downloaded the world country geodatabase available from ESRI (https://www.arcgis.com/home/item.html?id=3864c63872d84aec91933618e3815dd2), merged it with my data and then used the tool
Areal Interpolation from the geostatistical wizard.
At step 2, I received the
error 40066: cannot distinguish between polygons which presumably occurs because some polygons (islands) are much smaller than others. As suggested in the ESRI help, I used the tool
Delete Identical to identify and delete those polygons that ArcGIS could not distinguish between. Apparently, this was successful but when I tried to continue with the Areal Interpolation I got the same
error 40066 again.
Did anyone have similar problems?
