AFAIK the JOSM measurement tool does not provide very exact measurements but is a bearable approximation. Not sure if this matters to you, but I guess you shouldn't rely too much on the displayed values. See for instance: http://josm.openstreetmap.de/ticket/4849 You should also be careful not to select nodes as well: http://josm.openstreetmap.de/ticket/6872 cheers, Martin PS: Maybe the first issue has to do with projections and the way these calculations are done (flat vs. elliptical), and it may well be that the differences are not significant, dependant on where you measure and how long the distances are. _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
