What Dan said is correct, and even if you did have all the meridians you
still could not do what you want without additional information (like the
county). There are some states that have multiple zones (Mississippi -
many; Oklahoma - the panhandle is different; Louisiana - East of the
Mississippi River is different), and the same PLSS S/T/R coordinates appear
in different places within the same state.
It is a BIG mess for some states. I'm just glad they didn't mess it up too
badly here in Florida, except for all those darn Spanish land grants.
