[Qgis-user] Split Feature (Line) creates many segments

[Springfield Harrison]

Hello,

I have a long flight line which crosses itself many times.  I want to 
trim the ends.  The Split Featured tool works as intended but the line 
is broken into many segments between the intersections. This I can cope 
with.

What also happens is that the total line length increases. Visually the 
segmented line looks identical to the original but the total length of 
all the segments is greater than that of the original, in some cases.

Any help would be much appreciated, the line segment length must not be 
altered…

Cheers, Spring
