[postgis-users] How to use ST_Affine

[Frank Durstewitz]

Hi,

i wonder how i would use ST_Affine. I found a small note how to use 
(with R), but that's over my mind.

I want to shift the coordinates of some points. On a map i show the 
points, then i select at least 3 of them to move them manually to the 
correct coordinates and use the new coordinates as reference for the 
shift. So i have 3 "old" coordinates and 3 "new" cordinates. But i don't 
know what goes where...

Can someone please explain what to do?

Regards, Frank
