I have a shapefile for the boundaries of European NUTS regions, and I would like to compute the centroid for each of those regions. When I do this in QGIS (2.6.1 on OSX, using
polygon centroids from the fTools menu), I get multiple centroids per region. Sometimes the centroids are nearly overlapping, sometimes they are further apart. How can this be? Am I doing something wrong? To be complete: I am using the
NUTS_BN_60M_2006.shp data, available from Eurostat
I've added a screenshot; this part is particularly bad, but other regions have the issue as well.
