Hi all,<br><br>I'm trying to use v.delaunay to get the lines connecting centroids in thiessen polygons because I need to compute some statistics on the length of those segments.<br>I'm facing a problem that maybe somebody could help me to solve.<br>
<br>Basically I run v.delaunay with the -l option to get lines instead of the polygons, I get the resulting vector, but there is no attribute tables associated to it.<br>My idea was to run v.db.addtable to create a new empty attribute table, then v.category to assign cat numbers and the v.to.db to compute and add to the attribute table the parameter I need (ie the length).<br>
The problem is that when I run v.category nothing happens, and the attribute table remains empty.<br><br>Am I missing somethng?<br><br>Any help appreciated.<br><br>Ing. Andrea Pogliaghi<br>Milano - Italy<br>
