Extended Statewide PLSS Corner Numbering System

This publication outlines an extension to the Statewide PLSS Corner Numbering System, also known as the Romportl Numbering System. The need for an extended version of the system arises from several special cases known to occur in Wisconsin: fractional townships; and corners in adjacent states to which surveys in Wisconsin are tied. The SCO plans to maintain both the standard 11-character corner number and the 20-character extended corner number in the statewide PLSS database. Counties with special cases may need to adopt the extended system.
