I have a boundary shapefile of a city with 19 district boundaries, and I need to reflect some changes and create 16 districts instead.

Boundaries I want to merge are all neighboring districts (two neighboring districts need to become one).

I'm a beginner so I'm not sure what I should be doing to get at this, please give me some advice! I'm using ArcMap 10.5

  • Are you adjusting the position of the boundaries at all, or are you just wanting to merge existing polygons? – Midavalo May 26 '17 at 14:57
  • @Midavalo Just merging, about 3 pairs in total – song0089 May 26 '17 at 15:03

Start Editing

enter image description here

Select two districts you want to merge into one, and from the Editor toolbar menu select "Merge"

enter image description here

A dialog will appear for you to select which record to copy attributes from - select the one you want to keep attributes and click OK

enter image description here

Your selected polygons will now be merged. Repeat for the other districts you would like to merge.
