Hi Gerd,

I have looked at your example file in QGIS and Global Mapper and they 
show distance like JOSM. I don't know why there is so big difference. My 
guess is that it could be caused by spherical versus ellipsoidal model 
of the Earth. Maybe you could test algorithms based on Vincenty's 
formulae? See for example:
