Currently, I am developing a QLikSense application that contains a map of the Netherlands divided in it's counties and communities. So far I could find a KML file for the counties very easy at https://www.pdok.nl/en/node/358. The result combined with NAW and postal code data is:
I found PDOK Viewer and selected 'Bestuurlijke grenzen' > 'Gemeentegrenzen'. The map that I got on the webpage is exactly what I need but I can't find a way the obtain the KML file.
