Was thinking I would start counting, but if I include 22kV distribution lines then there are probably thousands of taps around the country.
Some examples on openinframap:
4 taps on this one for the 132kV lines: https://openinframap.org/#17.9/59.276012/9.543613
3 taps here: https://openinframap.org/#17.9/59.727655/9.819084
2 here: https://openinframap.org/#17.57/59.132268/9.474693

There are many many more :)

Mid air taps are quite common in those types of junctions actually. The tower on the through line is an anchor termination tower with no connection of the line, so it has to go via the two branch ones to the nearby substation.

Hard to find visual examples of this, but here is one close to a streetview: https://goo.gl/maps/cXHLkhVzvFfwpy4V8

Lines can have a mid air tap where one crosses over the other. there is no connection like you did. Problem is it is impossible to know for the validator if there should be a tower at a node or not, so you can't remove it.

Also keep in mind we might have used plan drawings to add a road that is not yet in the official Kartverket road database. These are often found on road project websites.
If you don't find a match, ask the previous editor first.

The Norway Orthophoto layer should never be older than around 5 years, but it varies. The low res images(0.25m) are normally rotated every 5 years and is funded by Kartverket. For more central locations the municipality may request higher res images as often as once a year. This typically the cities that have a bigger budget for these things.

What is showing in iD is normally the most recent one even if its the low res image.

The "kartverket road network" overlay is the best one to use. Its a bit spotty with iD as the sever don't like to many requests at once.

The N50 layer is actually currently showing way to much. It's supposed to be 1:50000 max. The resolution it's currently showing we are not legally allowed to use. Keep that in mind.

Make sure to check with all sources before moving roads. Aerials might not be up to date. The segment of highway 13 between the bridge and tunnel was perfect, but you moved it for some reason.
If you could revert that part it would be nice.

Nice import work for Vik btw!

Why did you add fictional lines inside the power station at Three Gorges Dam?

Nice maping, but please don't attach land use/cover to roads and buildings. They are not related and cause a maintenance nightmare later on.

Trur du har misforstått gang og sykkelveg som er segregert.

Kopling til Flyplassvege ved Meyerskiftet busstopp er neppe rett. Dei som skal bort til til nummer 32 og 36 må faktisk køyre via Grimseidvegen og så inn på Siljustølsvegen. Så via gang og sykkelvegen vidare bort.

A tip, there are another two 132k lines just north of that spot which would show typical H tower size for this voltage level.

I use multiple sources/layers available to keep lines up to date. Imagery, Karverket DOM, Aviation obstacle and NVE data. Unfortunately the DOM and DTM layers don't work in iD as they haven't updated the wms links.

If you have any questions just ask. I've been mapping lines above the 22kV distribution gird over the past few years, and trying to keep it as up to date as possible.

Norway Orthophoto imagery should not be blurry. But they can be a few years old in some cases. The low res images are 0.25m refreshed every 5 years. Higher res is 0.1m or better and is more random. Current image for this area is from 2018, and the line was completed in 2019/20 I believe.

You can actually check age by going to norgeibilder.no There is a small globe icon top right which can change UI to English.

Sorry if I came on a bit direct. Had to deal with random people breaking the power grid over the years. To be honest if you think connecting a 132kV line to a 22kV tower/pole sounds reasonable, then you don't know what you're doing ;) There is a big difference in size on towers/poles between those voltage levels.

Please do not mess with the power lines if you don't know what you're doing. This 132kV line is new and have no connection to the 22kV distribution network below it. The towers are placed based on new Aviation obstacle data available as a layer in editor.

People tag for the renderer by using the banket tags. Its only access= values that show up on the map. So you end up with a bunch of overrides making the tag list unnecessary long.
Norwegian sign 306.1 should be tagged a motor_vehicle=no

If i left some tags stating use sidepath, then that is an oversight by me.

For Bergen light rail you can look at the strong criteria for light rail over tram on the wiki page you linked.

And please do not mess with access tags if you do not know how they work in Norway. Agnes Mowinckels gate has a sign forbidding general motor vehicles except buses. the access=no tag is not used here unless its forbidden for all traffic modes. You effectively blocked walking and biking on the road.

Please revert the Bergen light rail back to its original tag. It is not a tram as it is fully signaled and on dedicated track for most of the line.

The N50 data is made up of areas. Someone destroyed the wood relation south of it so it looks weird. I'll fix that.

Why did you add fictitious power lines at the dam? Please don't do that.

Added the foot and bicycle restrictions on fv510 as well now so it should be all good.
