Boundary demonstration and demarcation
Boundary demonstration is an unofficial measurement of the plot boundary to clarify the location of the boundary. Demarcation is an official boundary measurement operation that is entered in the property register. Demarcation is necessary when the boundary markings have disappeared or the location of the boundary is otherwise unclear. In the town plan area with a binding subdivision plan, boundary demonstrations and demarcations are carried out by the municipality. Elsewhere, the National Land Survey of Finland is responsible for demarcation. The National Land Survey of Finland does not make boundary demonstrations.
