Where did you find the distribution voltage for this area? The voltage regulators on the distribution lines in the area says 7620V which would mean 13.2kV L-L voltage.

Please don't mess with the bus stops in Norway. They are updated automatically and we dont use the public transportation tags. Many of them don't even have a platform so the public_transport=platform tag is wrong.

Har no fiksa alle valideringsfeil i området. Ver så snill å ikkje lag meir krøll er du snill.

Trur du må stoppe og redigere landcover til du forstår relasjonar og kan bruke desse. Du er på veg å rasere heile området med masse feil.

This is not a 420kV transformer. It is connected to the 300 and 132kV and has a third winding at 17kV that used to be connected to some capacitor banks.

That voltage may not be accurate. The AC voltage after converting from DC to AC is never 1:1. That is why I removed it in my edit. You have to ask the operator or manufacturer as this will vary from station to station. The most common to use is 0.636 as the average and 0.707 for RMS. So most likely the voltage is around 500kV, but it still purely guesswork.

There are different school of thought here unfortunately. Some want a value for every possible tag instead of using a default value if missing. Tagging with every key and value available in OSM will lead to a lot of tags per object.

Probably because you used Bing aerials. Those are not to be used in Norway as they usually have a bad offset. No idea what imagery is available, but in iD the Norway Orthophoto is default and best option.

I just called the ferry operating the route to clarify. The Gudvangen-Kaupanger ferry no longer go via Frønningen or Styvi. It also only operates 1. May - 1. September. From 2024 there is a separate ferry Kaupanger-Frønningen. Styvi is served via the electric passenger ferry between Gudvangen and Flåm.

It is the same service. Fjord1 operates this in summer months. AFAIK the ferry still calls at Frønningen on request. Same with Styvi. It seems as though there is a separate ferry Kaupanger-Frønningen these days. Maybe more appropriate to update the existing route as there are not two separate routes here.

Adding bicycle=designated on a cycleway is pointless tag bloat. It's implied via highway=cycleway Tags like this could get removed via a validator we use here in Norway.

This is a duplicate of the already existing ferry line. The ferry go via Frønningen if needed.

Du har blanda produksjon og effekt. Fennefoss er 9,5 MW. Produksjon har ingen tag i OSM.

Please do not add small road link segments to intersections unless its a slip separated from the rest. Also the same for bus stops and passing places.

No problem. New fuel pumps? Didn't see them in pictures from last year.

Did you add duplicate fuel station on purpose? There are two nodes at this location now.

If you wanted to map the "shed" the chargers are under it would be a building or something. Not tagged as a charging station. If you do it will appear as a duplicate. I really don't see the point in adding such sheds as they have no value for people. If the whole parking lot where you park to charge was covered then it has a nice function.

Please don't add duplicate charging area where there is a node. EV chargers should only be a node as well.

Please don't map this as 3 circuits. 1-2 form one circuit and 3+4 is one. Thus the line only contains 2 circuits. (1+2) and 3, so technically 1.5 circuits as 4 is in the ground. Bipolar HVDCs are considered as a single circuit even though they technically can run at reduced capacity using electrode if one pole is down.

They can happen in some places. For the "ring" around Birmingham it's historical. Several substations used to have 275kV switchgear and as they get upgraded they have to mix. Several substations are still 275kV in Birmingham.
You can see how it all connects on Openinframap
