[GRASS-user] Water boundaries to stream network...

[Jonathan Greenberg]

I have a large, complex single polygon (with donuts) that represents the 
boundary of the Sacramento Bay Delta rivers -- I would like to generate 
a line network running down the center of this boundary, but I'm having 
a hard time accomplishing this.  Any ideas?  I believe this is referred 
to as the polygon "skeleton".
