Talk:State Plane Coordinate System

From Wikipedia, the free encyclopedia

I tried to find a map of the US showing the state plane zones, but did not have the time to find a nice one that clearly was available to use here (copyright-wise). I'm sure there are some out there. If someone knows of one let me know or add it! I'll do it if I have more time and inspiration later... Pfly 03:32, 28 October 2006 (UTC)

[edit] Where can I find the math?

I am trying to write code to deal with this thing. Does anyone know where to find the equations?
