Hey All,

I have a small problem, which I think shouldn be a big deal. However, so far I cant figure out the solution. Therefore, I am very thankful for your help.
I have a shape-file with polygones. I want to simplyfy this shape-file. Therefore, I would like to join polygones if they have the same value and are neighboring. I do not want to run the funktion dissolve, because then I get one big polygone for all polygones with the given value.

Thank you!

Dissolve should do exactly what you want.  Perhaps you need to uncheck Create Multipart Features?

Yes, the difference between "multipart polygons" and "multiple (single part) polygons" may be confusing at first.
Multipart makes all the scattered bits one single feature (regardless of if they touch or not)
Single-part makes many individual features (it dissolves them only if they touch).
