Hi! all,<br>
just a random exercise!<br>
<br>
if I have a set of lines then can they be connected through
their endpoints to the nearest end-point of nearest line, thus
creating a single line.<br>

You might be able to use the combination: <br>
v.edit tool=snap thresh=-1,xxx # where xxx is some relevant
threshold value<br>
and then<br>
v.build.polylines<br>
<br>

Can we have a line generated through the centroids of the
polygons in a single command.<br>

<br>
How about this:<br>
First get the points from the centroids:<br>
v.type in=polygons out=centroid_points type=centroid,point<br>
Now run that point vector thru this pipe:<br>
v.out.ascii centroid_points | v.in.lines in=- out=centroid_lines<br>
<br>
(Note that the lines will be connected in whatever order the
polygons appear. Might result in spaghetti...)<br>
