State Plane Coordinate Legislation

Each state has taken it's own approach on legislating mapping requirements. Horizontal datums and survey foot specifications have been defined in nearly every state; vertical datums are rarely legislated.  Below is a table and accompanying map showing how legislation has been approached in each state, along with names of the bills in each state.

 *    Foot Conversion:

 

U.S. Survey Foot             1 ft = 1200/3937 m               1 m = 3.280833333 ft.

International Foot           1 ft = 0.3048 m                     1 m = 3.2808398950 ft.

While legislation can be found on the internet, links frequently change, and so are not provided here.  An online search via your browser, using the title of the bill, should provide the current link to your bill.
