</P>
<P><SPAN LANG="en-us"><FONT SIZE=2 FACE="Arial">Looking for a some ideas and help.</FONT></SPAN>

<P><SPAN LANG="en-us"><FONT SIZE=2 FACE="Arial">I am ttrying to use the v.voronoi (in wingrass) tool and it is perplexing me with the results I am getting. Here is the scenario.</FONT></SPAN></P>
<P><SPAN LANG="en-us"><FONT SIZE=2 FACE="Arial">I am trying to anaylise the spatial distribution of road intersections. I started with a road network file from Statistics Canada, and clipped out the roads of the city of Ottawa for my subset. I created a new vector containing only the nodes of the Ottawa network. The resulting vector has the following basic stats</FONT></SPAN></P>

<P><SPAN LANG="en-us"><FONT SIZE=2 FACE="Arial">The nodes represent both road terminations and intersections.</FONT></SPAN>

<P><SPAN LANG="en-us"><FONT SIZE=2 FACE="Arial">I am new to using Voronoi charts but when I run the v.voronoi script I expect it to create a polygon for each node.</FONT></SPAN>

<P><SPAN LANG="en-us"><FONT SIZE=2 FACE="Arial">Instead when I run the basic stats on the new Veronoi vector I get:</FONT></SPAN>

<P><SPAN LANG="en-us"><FONT SIZE=2 FACE="Arial">I get a rectangular shape that is located just north of ONE of the nodes in the coverage. As I zoom out some other nodes apear surounding rectangualr shape… The manual doesn't shed light on my situation.</FONT></SPAN></P>
