I have a shape file with 545 contiguous polygons all carrying different values (precinct#'s). From this file, I have generated a Neighboring polygon analysis table reporting by each of the 545 precincts (Example attached). This table shows me each of the adjacent/neighboring precincts for each of the 545 original precincts. What I need to do is create a new polygon based on this analysis table where I can dissolve the adjacent precincts into a new vicinity. I can't seem to do this with a table. It needs to be a feature class. I've tried joining the analysis table to the original shape file, however because this table is a one-to-many, I am not getting all my records returned. I'm hoping that I'm just missing a step or that there is an easier way to go about getting a new shape file.
I've only been a GIS staff member using ArcMap for about a month now, so ANY help is greatly appreciated!
