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 9.2. So any solution based on Arc9.2 or QGIS 1.6 is highly appreciated.

Also, please note that the match option "closest" is not available in Spatial Join in ArcMap 9.2 –  Janus Jul 3 '12 at 12:26
    
What match options do you have in 9.2? If you have within_a_ distance you could play with that to catch most of the districts and then manually complete the outliers. –  Baltok Jul 3 '12 at 16:44
    
ArcGIS 9.2 is a retired version so, in the absence of any activity here in nearly 12 months I have voted for it to be closed as "too localized in time". –  PolyGeo Jun 6 '13 at 21:50
