Om du sjekker wiki så snakkar den faktisk om city for byer over 100k.
Ein kan ikkje bruke bystatus i OSM.

Trur vi må ta vurdering etter andre kriterier. Rjukan har også by status men under 1500 innbyggere ;)

Why was Ski upgraded to city? If a place with 10-15000 people is considered a city then we have a lot of them :)

Listed population is for the entire municipality and not the town itself. According to SSB the town itself has 12344. Population number set currently includes Ås as well.

A Bing offset of 2.35; 13.70 is good for the houses you added.

Please undo this set. Aerials in this area is badly aligned. Its clearly visible when you look at the house numbers. They are from the Norwegian mapping agency and are normally accurate to less than a meter. They are also normally placed at the house main entrance.

Du har sett feil klasse på fv 561. Den skal vere primary.

Never use Bing to correct data unless you've surveyed it. Especially house number nodes are never to be moved unless surveyed. Data from the Norwegian Mapping Authority (Kartverket) is usually of better quality. If you notice a large number of number nodes not aligning with Bing then Bing is most likely bad.
I have now fixed most of the bad edit and added more details. Bing in Masfjorden is terribly ofset and even a bit rotated so don't use it there.

Do not move house numbers imported from the Norwegian Mapping Authority unless you know it is wrong from gps or local knowledge. And never use Bing over data from "Kartverket". Only reason to do that is if you have local knowledge from survey or GPS that match Bing.

I have already corrected the house number nodes and roads moved in this changeset.

The number of digits have nothing to do with it. Its the background of the sign that is important. National roads and E routes use green. Primary county roads use white.
Keep in mind the Norwegian Public Roads Administration are sometimes slow to replace signs if they change something. Like the national road 7 over Hardangervidda. There are several number signs that are still the old white after over 5 years. The change is mentioned here: osm.wiki/No:Map_Features#Different_names_on_highways_in_Norway

Please revert the road class changes. They are wrong. E route and national highways in Norway are trunk class.

Please do not change road class unless you know how the system works in Norway. This road is a national highway and is therefore a trunk road. Please revert this change.

Why did you change this? This road is an E route road and thus should be trunk. All E routes and national highways in Norway will always be trunk or higher class.

Kva source har du brukt? Manuel leiting på nett?

Denne laga veldig mange duplikat. Ver så snill å samle data med eksisterande.

Waste of time to do any coastline edits with Bing in Norway. They are being updated slowly by better data from Norwegian Mapping Authority. Bing is also not adviced to use much in Norway as its often badly georeferenced.

Wikien kan endrast litt. Strava ligg inne alt og treng ikkje leggjast til i JOSM

Hah! Ja Bing er håplaust mange plassar. Ser at fv60 frå Hellesylt til Sykkylven er ganske ille. Skal sjå om eg kan ta den med NVDB/Elveg overlay ein dag.

Er nokre tettstader som er mappa med dårleg Bing som vil krevje masse arbeid å rette opp i.

Stemmer. Det var vel ledebil gjennom der ei stund.

Kvar har du dette frå?

651 Volda-Nordfjordeid is still a national highway and thus a trunk road. Please revert this change.
