I have been looking for the answer to this question for some time now, but can't seem to find it! My problem is straight forward: I have one layer It contains lots of features (only polygons), say countrys I want to merge some features together. Using python.
I know that I can select features with the mouse and hit the "Merge selected features"-button, but that is to slow. I can use python to select the features that i want, but how can i merge the selected features from python? (the features don't have a "common field" or something like that, what features are to be merged will be decided by in-data)
Help is greatly appreciated!
