[postgis-users] use of the affine() function

[Dylan Beaudette]

I have a problematic TIGER  module - i.e. a single county in Ca is really 
messed up. I thought that a simple translate() would do the job, but it looks 
like there is both a translation and rotation involved. I do not really 
understand the postgis manual entry for the affine function.

How would one go about converting a series of coordinate pairs ([good], [bad]) 
into the terms of the affine transform matrix?

thanks,
