[Qgis-user] SPLIT POLYGONS INTO 3 PARTS

[Thayer Young]

 Hi Azzurra,
To add to what Nicolas wrote. In case you use PostGIS, there is a procedure ST_Segmentize http://postgis.net/docs/ST_Segmentize.html that does this in one step for polygons. I believe it uses the k-means and Voronoi polygons method described by tjukanov on the GISStackExchange article.
