Those "plot "maps are platt maps. countys have them printed out and sale them . around here they are $35.00 alot of money for a black and white map with nothing but lines and names. no terrain features other than roads and creeks or large bodies of water.
yes the info is free but most countys want money for the maps. and legally your not supposed to copy platts but timber companys do for leases to show what you leased.
