Please do NOT use Bing aerial in Norway!
Use the Norwegian orthophoto that should be default.

I had a hard time finding appropriate tags when I mapped this. The wiki is kind of messy when it comes to hydro power and all its components. I didn't map many of these tunnels for the plants as the data is very basic.

Do not change hamlets. It is not OSMs responsibility to fix geocoding errors. Read about tagging Norwegian places on wiki.

This is not how you add a place. Notsete is already there as a farm. Please read the wiki properly before you continue to edit.

Please dont put addr:* tags on roads they do not belong there. Addr nodes should also be left alone as they are updated from Kartverket. If there is an error please report it at rettikartet.no

Velkommen til OSM. Lite tips... ikkje gi navn (naust) til bygning på den måten. Name= brukast om bygningen har eit spesielt unikt namn eller når det er ein butikk eller firma som har heile bygningen. Type bygning skal vere i building= verdien så her vil nok kanskje building=boathouse vere passande.

Tertiary er typisk brukt for vegar som har bussruter.

Thanks for spotting that one. Somehow a duplicated node got left behind and JOSM validator never warned me.

A firing range is not always military area. There are separate tag for firing range.

Would be nice if you actually added the poles to the power line and changed it to a minor line. Saves a lot of work later ;)

Why did you move the Fortum charger to the middle of a building? Please do not change things if you have no local knowledge.

Would be nice if you could add the socket type and how many for each charging station.

Highly doubt there is a car rental in the middle of an intersection between a road and a cycleway...

So what happen to barriers with no access tags? I hope you ignore them in that case. People may survey a gate and add it, but do not know the access rights for said gate.

This is a router problem not OSM problem. We can't add access tags for every conceivable option. Defaults are here: osm.wiki/OSM_tags_for_routing/Access-Restrictions#Norway

Please make sure you tag power lines properly. These are minor lines with poles because they are probably 22KV.

way/563713495 to be clear

Please do not add power lines without doing research. NVE data is outdated. This line was dismantled around two years ago when the new 420kV line through Sogn og Fjordane was completed.

What was the reason for this? One way tags are not used on roads with two way traffic. You've made E39 impossible to route in one direction now.

How did you spot this error?
