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

[j.rolland]

Hi Daniel,

Of course that I am interested, say me how I can contribute my share. 
As I indicate it in my blog, I can develop a function which turns over the 
skeleton from a polygon. Give me your specifications and I would study them.  


cordially,
Jérôme
