[GRASS-user] r.contour contour wrap

[Heidi Ochis]

Using a USGS 10 meter NED elevation model, r.contour in versions 5, 64 
and 72 create contours that trace back on themselves anytime the contour 
exits the grid.  Islands are the only lines that do not create a line 
with duplicate points.


How do I resolve this?


Thank you,


Heidi Ochis
