[mkgmap-dev] change handling of railway=abandoned
From AnkEric eric_internet at casema.nl on Tue Jan 21 13:28:19 GMT 2020
Just for the sake of argument: I don't like [access=no]. It's suggesting [access=no] is "default" access (which it's not). Next step is to add the Exceptions: [bicycle=yes], [foot=yes]. Double denial, Conflicting information, Contradictio in terminis. Also wondering: when is [access=no] - ever - correct? Nuclear power plant? No: [access=private] (staff). Nature Reserve (restricted access)? No: [access=private] (staff)/emergency. Abandoned railway? No highway implies: "no access". IMO: [railway=abandoned] is a property of (most typical) a cycleway, indicating max 2% incline, straight way (dull, imo), often "cutting=yes" (so: no view). Also: not two ways (railway and highway), but one way only. Either railway OR highway (+railway tag as property). In the Netherlands this "sloppy mapping" (IMO) resulted in ERRORS after MANY years. 1. [highway=footway] 2. [highway=path] (because without traffic_sign, SOME Mappers argue: this is not a footway) 3. [highway=path] + [access=no] (because bicycle/moped/mofa now have default access) + foot=yes (explicitly mapping the exception) 4. IMPROVED by UPDATE: [highway=footway] + [access=no] + [foot=yes] 5. DELETE [foot=yes] (because this is default access: "Needless tagging") 5. NOW on the MAP: [highway=footway] + [access=no] This is an Error: to Resolve many Changesets have been Reverted by DWG in which "foot = yes" was deleted ("Needless tagging") AND [foot=yes] was ADDED. Not only for [highway=footway] + [access=no] (tens of ways, at most) BUT for ALL Reverted footways (thousands). 6. NOW on the MAP: [highway=footway] + [foot=yes] (thousands of footways in the Netherlands) 7. JOSM now complains for EVERY Changeset Validation: "unnecessary tag - foot=yes|designated is unnecessary for highway=footway|pedestrian" And I don't "dare" to delete…. Other example: [highway=unclassified/track/path] + [access=no] + [foot=yes] + [bicycle=yes] I would prefer: [highway=unclassified] + [motor_vehicle=no] Long time ago I argued on a forum: I buy bread in a bakery: "One brown bread please." "Here you are. Anything else?" "No! Two croissants." / AnkEric -- Sent from: http://gis.19327.n8.nabble.com/Mkgmap-Development-f5324443.html
