Datum Modernization Project
Project to convert the Survey control network from a 1927 vintage to a 1988 vintage. The survey monuments are the positions that all property (parcel) changes are controlled from. This project will only be for the horizontal or flat surface area control. The vertical or elevation control will be completed as a 7 County, (SEWRPC area), after the horizontal is completed. SEWRPC will be performing the work in house and will supply Milwaukee County with updated data and documentation of the work performed.
- A datum is the position on the earth that measurements are taken from in surveying. It is important that these measurements are highly accurate to limit the amount of error that surveyors experience when they record these measurements that affect property ownership.
- “Datum Modernization” is in support of the Land Information Office’s Land Records Modernization plan as required by Wis. Statute 59.72 (3)(b). This project is also required as part of the 2016 Wisconsin Land Information Program Strategic Initiative – Benchmark 4 (Completion and Integration of the Public Survey System, PLSS).
