[Qgis-user] length parameter in field-calculator

[Frederick Löbig]

Hey list,

when I calculate the length of a polyline with the field-calculator, the
value is different from the one measured with the measurement-tool.
I think that this is a problem with the geodetic differenze between the
real length, and the flat projected lenth.

My question now is: Wich of the two values is the exact one?

Cheers,
Freddy
