Is anyone aware of a way to import dual-carriageway roads as a single linestring?
There's a request at Openstreetmap-carto to render dual-carriageway roads differently at mid-zoom levels: https://github.com/gravitystorm/openstreetmap-carto/issues/3934 It doesn't appear that there are any tags in the database which hold this information. Ideally one would import a linestring midway between two highway ways, if they were tagged with the same highway class, name, and oneway=yes, but it could be difficult to get this right at locations where the two carriageways separate. Has anyone implemented a rendering that handles dual-carriageway roads, or designed a way to import such ways into a (rendering) database as a single linestring midway between the two OSM ways? - Joseph Eisenberg _______________________________________________ dev mailing list email@example.com https://lists.openstreetmap.org/listinfo/dev
