Offset in Vigelandsparken, Oslo

Posted by niklasbackman on 13 August 2013 in English (English)

Please use offset values "3.98, 8.05" in JOSM when editing Vigelandsparken in Oslo.

I happened to meet a gentleman from Oslo City planning, who kindly measured a spot for me (northern Ekkopunktet) near Monolitten. Values can be checked also here: https://www.dropbox.com/s/b77mj8kjn5pgesf/ekkopunktet_vigelandsparken.jpg

Location: Silkestrå, Skøyen, Ullern, Oslo, 0240, Norway

how many points did you measure? I fear that the differences aren't simple offsets but more complex, due to the way this imagery is produced.

I got measurements for 2 points, but only this one is shown in the jpg. The 2nd point is where the man is standing, about 10m from the Ekkopunktet. I have no idea if this is enough or not, but I was just slightly surprised of the large offset. And, that is changes so much between the two closest-zoom satellite images.

But really this can be changed. What I'd just like to have an exact starting point, although there's no idea for me to map with exact offsets if everyone else is mapping by satellite images.

Do you any ideas how this could be solved?
