problem with measurement plugin

[Hendrik75]

Using JOSM 4878 the measurement plugin gives wrong values for the area. It seems to be approx 3,3 times lesser as real.

For some new polygons not uploaded to the server, the measurement plugin displays 0 as area, but in the same time the correct length of the way forming it.

Can anyone confirm?

No cannot.
Please add some more information.(screenshot,small example osm file, josm and java version, operating system ...)

Did you try it with and new/empty preference directory and just measurement plugin installed ?

as an example i have made an screen shoot of way www.openstreetmap.org/browse/way/123191274

I had before renamed the folder
"c:\Documents and Settings\Hendrik\Application Data\JOSM\"
and re-installed the measurments plugin in order to have fresh and clean install.

Using WinXP, Sun Java Version 6 Update 29

Screen shoot of building 6,79m x 3,86m = 26,21m2

I get the same area for that example way 123191274. If I create a rectangle with the same dimensions here (latitude 60), measurement plugin reports the area as 25,61 m2, which is just a bit off. However, if I duplicate (ctrl+d) that example way 123191274 here, it turns up with dimensions of 3,64m x 2,07m and a reported area of 7,37 m2.

However, I haven't seen the "0 area" for not yet uploaded objects.

Java(TM) SE Runtime Environment (build 1.6.0_23-b05), Windows 7.
