Good to se more people working on the Oslo map. It is pretty rough in some areas.

Are you on the Norwegian mailing list? http://lists.nuug.no/mailman/listinfo/kart

I am not sure if this is a convention. See the description of aerodrome here:

As far as I have been able to find oout, all the Norwegian land borders are surveyed approxemately every 25 years.

The Norwegian-Russian border was fully surveyed in 1947, with only a partial survey in 1980-1982. A new full survey was planned in 2007, but is now expected to be surveyed in 2009, with final results ready in 2011 or 2012.

The Norwegian-Finnish border was last surveyed in 2000. The protocol includes ortophoto maps in scale 1:20000 for borders in rivers and lakes, and 1:50000 for the rest of the border. All documentation was also recorded on a CD.

The Norwegian-Swedish border was last surveyed in 1984-1987. New surveyed planned 2009.

There are two answers to this question:

The first is: Would you get identical answers if you asked Norwegian and Russian mapping agnecies about where the border is?
Probably not. Different coordinate systems, at least, could give a very minor difference.

The second is: Would officials from both countries point at the same point, if asked out in the field?
Proably, within a few millimetres. The border is marked with two poles 4 metres apart. The border is exactly in the middle, and runs in straight line between these points. Where there is a sharp turn, they look slightly different. See pictures at http://www.grensekom.no/merkinggrensen.php and http://www.grensekom.no/conduct%20and%20travel%20at%20the%20border.php

Along rivers, it is my understanding that there is not better definition of the border, than "the deepest point". This might also give a margin of error of at least few centimetres.

For a starter, I don't understand Russian. In addition, I don't think there are any laws in Russia requiring public agencies to disclose information.

I am not sure if there is a better way to do it, actually.

Good work! I was in Kongsberg a few weeks ago, and then things looked very different...

Just a couple of comments: Riksveg should have a RV prefix (RV40, not just 40, see http://wiki.openstreetmap.org/index.php/No:Map_Features) and when two road numbers are combined, they should be separated by semicolon, so E134;RV40.

And finally one small wish: Could you add the Kongsberg Defence and Aerospace industrial area? I think it is one of the places attracting most visitors, at least that was were I was going :-)

Again, very good work!

Keep up the good work!

Next: Naming the farms? :-)

Indeed, very nice work.

I was a bit uncelar about what feature I was talking thinking about. The extrusion tool is what I was thinking about:

Have you looked at the function in JOSM to make squares?

Jeg vil bare minne deg på at det stort sett er engelsk- og tysktalende som leser diaries. Det kan kanskje være lurt å skrive på et av disse språkene.
