I have a huge number of polygons that contain attribute field that represent number of offices inside each polygon. Now I want to merge all adjacent polygons which count (sum) of offices values is between 1000 and 2000. I want to do that using ArcGIS. I have idea to use Dissolve tool, Integrate tool and Merge tool, but I am not sure about steps in order to solve this.

  • 100 percent identical. If you dissolve result shown by rcvnode . Store you Shape s somewhere in Dropbox, I solve it in 10 minutes.

  • @FelixIP This is the link: dropbox.com/s/0c62n0cy5nebwl6/TEXAS.zip?dl=0 If you can describe step by step what have you done in my example that would be great. JOINT_COUNT field is a field depending on which count I want to merge the polygons. Thx

  • @FelixIP This is great. But could you please send me a script that you have used in my example (with my parameters). Sorry, I am new in coding.

I took your polygons and converted them to single parts. For each part I recomputed number of offices pro rata of parts count in parent polygon. I applied procedure and script from the post mentioned in my comments with tolerance 0.05 and 316 groups, i.e. I tried to create 316 groups from 3059 original polygons with each group containing 1500 offices (total of offices=475169 ):

This is statistics of dissolved:

And these are results. Note I removed islands because they have no neighbours in your definition.
