[postgis-users] Diagram of Voronoï to Squelettisation of polygon

[j.rolland]

hi,

I have just set up on my blog at the following address 
http://ageoguy.blogspot.com/2010/12/squ… ation.html
http://ageoguy.blogspot.com/2010/12/squ… ation.html  a tutorial (in french)
which presents an algorithm of surface squelettisation of waterway
(POLYGON).
I provide an example like all the necessary functions and requests which
will enable you to obtain the skeleton of the waterway as you can see it in
the capture below :

Jérôme
