I was searching on internet a way to smooth lines in postgis, something
different to just using simplify or the st_simplify approach, and I found an
impressive method developed by Mr. David Bitner, this is the post:
http://postgis.refractions.net/pipermail/postgis-users/2010-October/030264.html,
and the output PNG is very impressive.
I have a very similar problem as showed by Mr. Bitner, but just having only
longitude and latitude (two parameters instead of 4 as in the link above). I
tried already the simplify command and it doesn't give the smooth I want,
because it doesn't produce curves, even though I played with almost all the
reasonable values in the tolerance. Has anyone used this neat script
succesfully on longitude/latitude (e.g., navigation) tracks? or is there some
command already like that in postgis 1.5.3.??
Thanks in advance for any help,
