Hi

a friend of mine wants (needs?) to determine the angle between segments
in an ESRI polyline (line vector feature). As there does not seem to be
an easy way in ArcGIS 9.2, I thought about askeng here:

Is there way of calculating these angles between the different line
segments in grass?

Thanks,

Rainer
