Note: This wxGUI extension is available only in GRASS 7.
This tool has been developed within Google Summer of Code 2012, see related wiki page for details.
The tutorial is based on example atmanual page.
If you want to follow the tutorial on your computer download SPEARFISH data set and copy directory spearfish60 into your GIS Data Directory. When launching GRASS choose location spearfish60 and mapset user1.
Before you start work with Vector Network Analysis Tool you have to apply these commands in order to be able to follow tutorial video:
v.category in=roads out=myroads opt=add cat=1 layer=3 type=line v.db.addtable myroads layer=3 col="cat integer,label varchar(43)" v.to.db myroads layer=3 qlayer=1 opt=query qcolumn=label columns=label
Now you have created same myroads vector map as is used in the video tutorial.
