I'm having a bit of trouble with
ST_Buffer and join styles. Basically, if I try and use the
bevel style it outputs as if I was using the
I notice that the
ST_Buffer docs state that GEOS 3.2 or above is needed for
bevel to work. I'm using GEOS 3.3.7, but I've also tried downgrading to various GEOS versions (3.3.5, 3.3.0, etc) to no avail.
The only way I've managed to get
bevel to work is by using Postgres.app as my PostGIS database instead of my manual homebrew installation. I can't work out why my homebrew version doesn't do it even when they're both using the same GEOS (3.3.5).
Is there something that I'm missing? Perhaps I need to update / do something with my existing PostGIS database after downgrading / changing GEOS?
Basically, what I'm trying to achieve is an expanded polygon (say by 3 metres) with sharp corners.
ST_Buffer seems to be the logical choice here. However, I'm happy to explore other options that would a) let me remove the rounded corners after using
ST_Buffer, or b) let me use something other than
ST_Buffer to achieve the same effect.
