Frans S (2025-06-26 07:28:47+00:00): Hello. Thanks for mapping,
Please pay attention on these points
1 round hut has been mapped as a rectangular building. By mistake ?

You tend to oversize the buildings you map. Stay within the rooflines. These huts have an overhang, so they show to be bigger than they are.
You overlooked 2 buildings next to a tree a bit lower.
Best regards

Feedbavck  Robin  Op een voetpad mag je niet fietsen en ik zie ook nog een trottoir. Staat er niet gewoon een paaltje?
barrier=bollard
Dan routeert het ook niet meer voor autoverkeer.

Robin1133 (2025-06-26 08:12:50+00:00): Er staat blokkade voor auto's. Een soort vluchtheuvel. Er mag gewoon gefietst worden, maar ik wist niet hoe ik moest aangeven dat het zowel een fietspad als een voetpad is. Kan iemand mij hiermee helpen?
eggie (2025-06-26 08:26:54+00:00): Ik heb het net aangepast.
Je moet maar even kijken wat ik heb gedaan. 
Het is gewoon een highway=residential. Auto mogen gewoon parkeren in die parkeervakken.
Het zal niet routeren, want op dat vluchtheuveltje heb ik een barrier=bollard gezet.
Aanpassingen in routering doen er vaak een weekje over.
Volgende week even proberen. dan zie je het effect.
Groet

eggie (2025-06-26 08:32:42+00:00): De parkeervakken het ik ook ingetekend als voorbeeld. Bewijs dat het geen voetpad of fietspad is.

AwFi (2025-08-02 17:37:20+00:00): Ciao, ho visto la storia di alcune way che hai toccato in questo changeset, era stata fatta una maproulette per dividere le way highway dalle way railway, ma poi tu le hai riunite. Potresti seguire la wiki ed evitare di ripetere queste azioni per favore? Inoltre se vuoi segnalare corsie riservati ai mezzi pubblici c'è tutto il filone lanes:psv=* e psv:lanes=*, ti suggerisco di dare un'occhiata.
Buon Mapping!

du hast hier vor nem halben Jahr den Feldweg zu einem highway=cycleway gemacht. Weißt du zufällig noch, welches Verkehrszeichen den Zugang zum Weg regelt?

Grüße und ein Gutes Neues
silversurfer83
rolfdieter (2026-01-02 08:38:56+00:00): Moin
...und sorry - welches Verkehrszeichen - bin mir nicht sicher - aber das ist jetzt der offizielle Diemelradweg. Wo man früher links abbiegen musste ist jetzt ein Bike mit Pfeil geradeaus.
...gutes Neues!
silversurfer83 (2026-01-02 10:27:38+00:00): Moin

Steht da vielleicht irgendwo dieses Schild: 

https://wiki.openstreetmap.org/wiki/DE:Tag:traffic_sign%3DDE:240

Oder eher ein 250 / 260 + Fahrrad frei?
rolfdieter (2026-01-02 15:00:53+00:00): Nein - mit Sicherheit keins von beiden
rolfdieter (2026-01-02 15:10:53+00:00): Wenn du diesen link aufrufst

https://www.ace.de/ratgeber/rund-ums-zweirad/fahrrad/schilderkunde-radfahrer/

dann ist das entsprechende Zeichen unten als letztes dargestellt
silversurfer83 (2026-01-02 15:27:49+00:00): Ok. Das macht aus einem Feldweg noch kein highway=cycleway

Wege, die damit beschildert sind bekommen ein lcn=yes und wenn es weiter ein Feldweg ist, sollte es wieder highway=track werden
rolfdieter (2026-01-02 16:29:08+00:00): Ja gut - aber das ist doch kein Wirtschaftsweg der hauptsächlich für Land- und Forsrwirtschaft genutzt wird??!
silversurfer83 (2026-01-02 17:13:52+00:00): Wenn es ein Weg ist, der von zweispurigen Fahrzeugen gebutzt werden kann und wenn es ihnen nicht durch Verkehrszeichen verboten ist (oder Poller), dann ist es für uns entweder ein track oder ein unclassified.

Cycleway impliziert Verbot für alle außer Radfahrer. Deshalb frage ich nach den Verkehrszeichen, da diese für das Routing sehr wichtig sind.
rolfdieter (2026-01-02 17:49:24+00:00): ...das leuchtet ein. Diese Verkehrszeichen sind definitiv nicht vorhanden.
Frans S (2025-06-30 14:05:57+00:00): Hello. Thanks for mapping. A remark. 
Objects without a roof (shadow on both the in-and outside or no shadow at all) are not to be mapped as a building.
When an object shows no clear proof of human activity, paths, yards around a building and a shadow, it is most of the time no building.
Best regards and keep mapping.
