barriers on major roads
Hi all, I've just fixed a rare problem with barrier=* in r3206. Now I wonder if mkgmap should really process nodes with barrier=* that are at the start or end of one way. I found many cases in the past where this was a mapping error, e.g. If a small way is connected to a "major" road, and the connection node has barrier=gate, the current implementation will not allow cars to travel along the "major" road. The wiki recommends to avoid this situation: http://wiki.openstreetmap.org/wiki/Tag:barrier%3Dgate says "Avoid tagging highway intersections as that does not make clear which way has the impediment" I think mkgmap should print a warning if that is found and ignore the barrier. OK? Gerd
Hi Gerd, in most cases you will be correct with your assumption. But I cannot say for sure, that there isn't a case outside in reality, for which the tagging on crossing node is correct. So I'm not sure if ignoring would be helpful in every case. Maybe it would be a better thing to generate for such osm-bugs gpx-files, which contains the bugs. So it would be easy to fix them. Henning
Hi Henning, okay, for the beginning I'll only add a warning containing the url of the node. I'll do that when the refactoring is done. Gerd Henning Scholland wrote
