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.
