Hey Roland The reason I asked about whether there is a tool that finds (possibly wrong) duplicate mapped cycleways because a very similar algorithm could be used to determine whether any one street is actually *missing* cycleway tagging or whether the cycleway is in fact already tagged but as a separate way. In other words, I need all those roads that neither have a cycleway=* tag (easy) nor have a cycleway-way next to them (the hard part). I wonder, is this possible to achieve with an Overpass query?
I was told here https://github.com/westnordost/StreetComplete/issues/139#issuecomment-297518195 by an Osmose-backend contributor that they implemented this already, but of course, Osmose does direct postgis queries, so more is possible with this. https://github.com/osm-fr/osmose-backend/blob/master/analysers/analyser_osmosis_cycleway_track.py I am developing an app with which one should be able to map cycleways basically by simply answering the question "Is there a cycleway here?" and of course, the app needs to find out, where it may ask and where it shouldn't.
