Township Duplicate Status

If there are multiple townships in a Public Land Survey System Origin, State and Survey Name, the Township Duplicate Status is used to establish uniqueness. When more than one Public Land Survey System Township has the same Township and Range numbers and directions and fractions, and are in the same State, this attribute is used to distinguish among duplicate values.

Domain: first duplicate - This value is applied to the duplicate Public Land Survey System Township which is closest to the base line of the Public Land Survey System Origin. If both Public Land Survey System Townships are equidistance from the base line, than the one closest to the Meridian of the Public Land Survey System Origin is assigned the value first duplicate. This was formerly known as code a or in the Ohio Symmes Purchase as code f.

second duplicate - This is the attribute value assigned to the Public Land Survey System Township that is furthest from the Public Land Survey System origin. This was formerly known as code b.
