I have a point layer in QGIS, which I want to filter by attribute values of a specific attribute column. For each unique attribute value, a centroid should be calculated from the respective features. This results in one centroid for each set of features containing a unique attribute value.
Example: In the attribute column 'names', I have 10 features named 'aaa', 20 features named 'bbb', and so on. Now I want to create a centroid of the respective 10 'aaa' features, another centroid of the respective 20 'bbb' features, etc.
Anyone has some hints on how to do this?
