Combining Multiple Polygons Into One Polygon By Area

Question asked by on Aug 4, 2015



Thank you in advance for helping with my question. I am trying to combine multiple drought layers by a single attribute (drought level). I want the output to be a single shapefile but the drought levels to be displayed as the average distance between the two previous layers.


To clarify: If the drought level is a 0, 1, or 2 value I still want the outputs to be a 0, 1, or 2 and not the average value 0.5, 1.5 (that a spatial join would produce), however, I want the areas to be displayed as half way between the first polygon and the second. I.e. One large polygon and one small polygon produce one medium polygon.


Thank you very much!
