I have a polygon layer and I want to dissolve the polygons according to a specific field. But I want sth extra. I would like to dissolve only the neighbours polygons. For example, look at the below image.

I would like the marked polygons with a red pen to be different features.

Is there any possible way? I use QGIS but any answer in ArcGIS is acceptable.


If the polygons you want to dissolve are few, then you can merge them manually using Merge tool, as you can see below:

enter image description here

Start editing → Select the polygon you want to merge → it will prompt you a table to choose which field you want to use. Then select that feature and click OK.

ArcGIS has the same tool. Go to Editor → Start editing → Select the polygons you want to merge → Go to editor and select Merge.

Right-click the toolbar panel and Select Advanced Digitizing toolbar, as you can see below:

  • It is not Plugin, it comes with QGIS. I am using QGIS 2.14.7. See the updated answer.

You could try to run Multiparts to Singleparts function after dissolving. Features that do not touch should become singleparts.
