I have a vector layer containing several points and I would like to generate the mean coordinates of these points, using QGIS only if possible. I'm looking for something similar to centroids, but for points. Any hint?
If your points have a common attribute you can run "Vector > Geoprocessing Tools > Convex Hull(s)..."
Input Vector = points Create convex hulls based on input field = check, use the field with the common attribute
This will create a polygon for each group of points. Now you can create your generalised points "Vector > Geometry Tools > Polygon Centroids..."
Convex hull creates a minimum area polygon around the points. The centroid of which will then be the generalized centroid for each point cluster.
