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?
I've never tried this in postgis, but JUMP has a good affine warping
tool (GUI) that I've used for smaller datasets. Might be worth a shot.
