Alles ziemlich undeutlich. Kann mir mal jemand sagen wie sich "gesunder Menschenverstand" in routing-Regeln umsetzen laesst? Das groesste Hindernis ist dabei, dass dummerweise der "gesunde Menschenverstand" sehr unterschiedlich ist. Da kommen wir nicht weiter.
Allerdings haben wir schon einige Grundregeln fuer Aenderungen, ueber die wir uns wohl einig sind: - Existierendes tagging darf nur in Einzelfaellen ohne Rueckspreache mit dem "Vortagger" geaenderte werden, und das nur dann, wenn das tagging falsch war, d.h entweder dem wiki oder der on-the-ground Situation widersprocht. - Das Entfernen anscheinend redundanter tags oder optionaler tags ist generell ohne Ruecksprache mit dem Autor ist unerwuenscht - Massenaenderungen sind immer wie Importe zu behandeln. Wir brauchen wahrscheinlich eine neue Tabelle im wiki: "OSM tag for routing/default values for highway tags" Hier ein erster Versuch einer solchen "Tabelle auf die Schnelle": highway=XXX; mandatory value (highway type) name=ABCDEFG; highly desirable; no default ref=XXX; highly desirable for numbered roads access tags - see wiki OSM_tags_for_routing/Access_restrictions <https://wiki.openstreetmap.org/wiki/OSM_tags_for_routing/Access_restrictions> Note that for access tags there is an access hierarchy <https://wiki.openstreetmap.org/wiki/Key:access#Land-based_transportation>. It is desirable to use for any exclusion or permission the highest vehicle in the hierarchy) lanes=number ; desirable for all roads; no default (maybe optional for single lane roads with explicit width or est_width values) lit=yes|no|(conditional value); no default maxspeed=number; mandatory value (for all road types, with the exception of some motorways in Germany, and of minor ways like track; path, footway, pedestrian) - there is also a wiki page OSM_tags_for_routing/Maxspeed <https://wiki.openstreetmap.org/wiki/OSM_tags_for_routing/Maxspeed> which contrasts with this !!! layer=number; default value:0; mandatory in case of unconnected crossing ways on one of the ways surface=XXX; desirable for all ways; no default smoothness=XXX; desirable for all ways; no default oneway=yes|no|-1; desirable for all roads; default value "no" bridge=XXX; mandatory for highways on bridges bridges; default value "no" tunnel=yes|no|xxx; mandatory for highways in tunnels; default value "no" embankment=yes|no; desirable for highways on embankmants; default value "no" cutting=yes|no; desirable for highways in cuttings; default value "no" incline=up|down|xx%; optional or desiranìble?; default value 0 lit=yes|no; desirable on all highways; no default (maybe except track and path with default value "no" ?) width=xxx, desirable on highways with no lanes value and highly desirable on sidewalks, foot/cycle ways, and foot/cycle lanes sidewalk=lft|right|both|use_sidewalk; desirable on all road-type highway; no default value narrow=yes; optional; default value "no" (this is a strange tag, as it refers to a *point* where the road is narrow) Overhead trolly lines; optional; deafalut value "no" tracktype=gradeX; optional on all types of minor highways; highly desirable on tracks; no default MTB_scale=X; not compatible with highways with implicit or explicit bicycle=no; optional (useless) on paved highways; desirable on unpaved paths; useful on unpaved tracks SAC_scale=X; only compatible with minor highways; desirable on extra-urban paths (definition???) and tracks trail_visibility=xxx; optional; default value "excellent" wheelchair=yes|no|limited; optional; no defined approach to default value (could be default=yes on all highways that allow pedestrians and paved surface with the exception of highway=path ?) ski=yes|no optional; no default value snow_mobile=yes|no optional; no default value (there are some more of these winter-sports related tags) Viel Spass beim Zerpfluecken Volker On Mon, 25 May 2020 at 22:25, Rainer via Talk-de <talk-de@openstreetmap.org> wrote: > > _______________________________________________ Talk-de mailing list Talk-de@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-de
