I have been tasked with aggregating precinct level voting data upto the county level. I have both the layers and I used the spatial join tool to do the aggregation.

However, there is a complication. On using INTERSECT as MATCH OPTION, i dont get the total number of votes as some of the PRECINCT LINES CROSS THE COUNTY LINES.

I used several other MATCH OPTIONS but didn't get the required results. Please suggest which MATCH OPTION should i use in order to get the total valueBelow is the image of the map i am working on. Take a look at the layers as well

  • I suggest to use match option of HAVE_THEIR_CENTER_IN to insure that the cenroids of the Precinct polygon are inside the county boundary. – ahmadhanb Jul 13 '18 at 7:35
