I have a point file depicting groundstations for rainfall measurment. I also have a polygon file representing districts of a state. I want to assign rainfall values in a particular district based on the station located there. I understand this can be achieved through a spatial join. However, I also want to assign these values to near by districts based on a value taken from the nearest station in the surrounding districts.
Please note that
- a single district can theoretically have multiple stations.
- I want to assign the exact value, and not an interpolated value.
I am working on ArcGIS Desktop 9.2.
