If you wait a few weeks we might have a server to access official rectified Norwegian imagery that will rarely have an offset of more than 1m. We have the permission to use the imagery, but not permission to use a cache server yet.

The DG imagery for area around Tana Bru is only off by about 5-10m at most.

Forgot to mention... at least now there should be several options to pick Kartverket data in JOSM when editing in Norway. This should help you align any imagery.

Any roads imported that use "Kartverket" as source will be a perfect source to align imagery to. This road data is the official data for Norway.

You even edited the riverbank after the construction of the new bridge at Tana Bru was added making it appear in the river. That should have made you realize something was off :)

If the riverbank matches your DG imagery then there is something very wrong at your end.

Did you forget to reset imagery offset? The entire riverbank of Tana river is misplaced now.

Hei, Velkomen til OSM :)
Ver snill og ikkje flytt på husnummer om du ikkje veit kva du gjer. Dei er henta frå Kartverket og skal vere plassert ved inngangen. Du må ha ein svært god GPS om du skal rette feil på desse. Om husnummer er feil plassert så kan du rapporterer dette på rettikartet.no

Ålesund er ikkje place=city, den er maks place=town. Les wiki om korleis vi set place tags i Norge ;)

Any errors to addr nodes can be reported to Kartverket at https://www.rettikartet.no/

Please do not to move and edit addr nodes as they are made semi automatic from Kartverket. These nodes are usually placed at the main entrance to the building.
Instead make a new node with the company info.

https://github.com/gravitystorm/openstreetmap-carto er plassen for det. Faktisk ein god ide at ein avgrensar ref visuelt på svært korte segment som dette.

"Tagging for the renderer" :P Ikkje bra ;)

This is wrong edit. You set the plant total output on each generator. Please dont.

Why did you change this generator to 270MW? Each of the 6 generators output 45MW not 270MW. That is the total output of the entire plant.

sorry.. feil changeset

Kanskje lurt å sjekke om det ligg ei kyrkje inne frå før? Sett dobbelt opp etter import

You have added the population for the entire municipality to the city nodes which is wrong.
Aso there are a set number of places in Norway that are defined as a city. These are not. Please read the wiki on tagging in Norway

Not a big deal as you did a small area. We all start somewhere :)
I'll ask for someone to revert the changes as I'm not experienced with that myself.

Mapping with aerials as the main source of info is not a good idea. They are often not aligned properly due to poor elevation data when georectifying them.
The Digital Globe Premium imagery is the best we got so far and is miles ahead of Bing.

We use official road data from Kartverket to position roads so unless you got a gps with 2 meter accuracy, so roads that got a source mentioning Kartverket and/or NVDB should not be moved to fit aerial imagery. The aerials should rather be aligned to fit the roads.

You've also connected house nodes to the road nodes and merged a house number node to a building. Address nodes are automatically updated from Kartverket and should be left as a separate node.
