Version mkgmap-r3623 was committed by gerd on Mon, 27 Jul 2015 Only produce a warning about a missing motorway ref when the node is a highway=motorway_junction. Carlos Dávila: Warnings about motorway exits in mkgmap.log include cases were motorway_junction is placed on motorway_link ways. According to wiki [1] motorway_junction may be used not only on motorway, but on other ways with named or numbered junctions, such as [2]. IMHO mkgmap shouldn't throw a warning in those cases. Regarding highway=services, if I recall right, it could be used time ago for exits that lead to service areas, but according to current wiki description [3] they are now only used for the place near the motorway where you can get the service (fuel, food, etc.) and then there's no need for them to be placed on a highway=* way. Warnings from places like [4] doesn't make much sense. Could it be reviewed to avoid checking things that don't need to be fixed?
