[GRASS-user] r.contour fails to close a contour at the region's border

[John Ciolek]

This is a re-post.

I have automatically generated raster data from which I create a contour using r.contour.  Sometimes the "feature" to be contoured is not completely contained within the specified region.  When this happens, r.contour generates an open contour - basically the beginning line segment point does not equal the ending line segment point.

Is there a way to get r.contour to close the contour at the region's border?  

If not, is there an easy way to close the contour?

Thanks
