Interpolating country by country feature

Discussion created by doby005 on Mar 3, 2011
I have a feature that I created with ArcMap 9.3 from a number of 0.5 grid rasters using map algebra. I now have country-level values for most of the countries but for countries that had missing raster values I have null values. I want to fill the missing values by using the values from nearby countries in the feature layer. Is there a way to do this at the feature layer level or do I need to go back and interpolate with the rasters before using map algebra? I know how to interpolate the rasters but would prefer interpolating using the values from the feature layer if possible.

Thank you for your help! I really appreciate it :)
