Hi, Micheal
Thanks for the reply. My use case is to add triangles between a pair of
polygons to get the amalgam. My polygons are in PostGIS
and what i do is, i get the union of polygon pair with a query in PostGIS
and output is converted into JTS and triangulated.
Then i find the triangles between them and add all of them with the union
pair. So the final result should be a polygon which does
not happen always. Where should i exactly apply geometry precision
reduction. Is it only to the union geometry from PostGIS or
do i need to apply it to output triangles as well?
Brian.
