Quality information
Property boundaries are marked with boundary markers in the terrain when forming a property. Boundary markers indicate the boundary lines of a property. A boundary can also be a natural terrain formation, such as a shore, drainage ditch or road.
In population centres, the Cadastral index map is mainly based on the municipality's large scale base map material in the plans, the property data of which has been updated.
There can be inaccuracies in the boundary data of the Cadastral index map (vector) because there are no exact coordinates for all boundary markers. The area of a register unit is shown in more detail in the cadastral survey documents (available in the archives of the keeper of the cadastral registry) and the terrain than on the Cadastral index map.
