----------------------------Original message----------------------------
I'm somewhat of a novice.  I have the 1995 GNIS data.  This data gives
latitude and longnatude of listed features on topographic maps (and
perhaps more).  My question is: is there a way to convert latitude and
longnatude to township, range, and subdivision and vice versa?
 
I didn't fully understand the post below, but it seems to relate to
what I am asking - I think.
