[postgis-users] More information on the new curve type

[Andreas Neumann]

Hello,

I am interested in the new curve type. Is there any information (either 
by ISO/Opengeospatial or Refractions) available with some examples?

Specifically, what geometry does the "curve" type support? Does it 
support spline curves (if yes, which ones) or arc segments? I understand 
that curve is sort of a superclass of Linestring, etc., but does it also 
support more complex curves like splines/beziers?

Thanks for any information,
Andreas
