There are some dead-end highway=service,oneway=yes that trigger dead-end-check warnings in mkgmap RouteNode.java. To allow suppressing most of the warnings, years ago I added a check that suppresses the warning if either end node of the way is tagged with fixme=* or FIXME=*, such as fixme=continue. This is not always applicable, for example when the oneway highway=service is leading to a tunnel, which is omitted from the map in order to avoid clutter (such as ways for underground parking) in city areas. I figured out that it would be nice to display all tags of the dead-end oneway, like we do in MultiPolygonRelation, so that my mkgmap wrapper script could filter out any oneway warnings for highway=service. Unfortunately, the RoadDef is in the Garmin domain, and there is no RoadDef.toTagString() method. Any ideas how to improve the diagnostics? Marko
