Also in your small code snippet you did't ensure that all your line where
simple linestring (and not multilinestring).
Just to be sure :
SELECT COUNT(*) FROM ukrds WHERE ST_IsSimple(geom)=FALSE

About sharp turns : you could use a small buffer then errosion or straight
skeleton (out of the box with sfcgal).
For the flat encapt I suggest you to use st_split afterward.

Apologies. I think I've just answered this myself. It's the
'endcap=flat join=round' bit isn't it. It's not doing what I am
expecting it to do. Though I'm not quite sure how to fix it yet.

Hi there,
Some code to
Does offset curve gives the same result?
(seems lile offsetting both side have same behavior)
Maybe you can try several buffers with increasing size?
(default appears wau before 1000)
Also, can you try to simplify your line : each coordinates uses 15 digits,
surely you don't need all of this !
Steve,
Thanks, you are of course right. I hadn't thought of that. Makes sense.
