[Qgis-user] SPLIT POLYGONS INTO 3 PARTS

[Thayer Young]

 Hi Andrea,
Sorry for the fake news. I meant to say ST_Subdivide, which I think is equivalent to what the original poster had tried and not been happy with.I was confusing this with the Paul Ramsey blog post that Guillermo pointed to, which is essentially a multistep PostGIS implementation of the procedure described in the GIS stack exchange answer. Sorry again. Thanks for pointing out my mistake.

Hi Thayer,
AFAIK PostGIS ST_Segmentize only works on lines and on perimeter of polygons
and doesn't split polygons in equal area.

Could you please give more info about the possibility to use ST_Segmentize
to split polygons in equal areas?

Regards.

Andrea
