I have a feature class with a bunch of single part polygons. Some of these polygons are within .25 miles of each other. I need to create a multipart polygon for each group of polygons that is within .25 miles of each other. Is there a means for automating this process?
You can try the following: 1. Use the Aggregte Polygons tool (Cartography - Generalization) with a distance tolerance to get aggregated polygons. 2. Use the Spatial Join or Intersect tool to associate the aggregated polygon IDs with their input polygons. 3. Use the Dissolve tool to dissolve the input polygons by the aggregated polygon IDs (check Create Multipart).
