Cadastral index map (vector)
The Cadastral index map shows location data of real property units. They include boundaries, boundary markers, property identifiers, and unseparated parcels of real property units and other register units. The product is open data.
You can take the product into use via the interface services or in file format in the Download geospatial data section on MapSite. You can read more about acquisition in the section Distribution and further information below. If you download the product with municipal boundaries on MapSite, it is good to know that parcels also include areas from the neighbouring municipality. You can make a more precise intersection in the client software, for instance with the Administrative areas product. The linear boundary data is, however, intersected according to municipal boundaries.
Other attribute data related to properties are available in the Cadastre. More information (in Finnish and Swedish): http://www.maanmittauslaitos.fi/kiinteistot/asiantuntevalle-kayttajalle/kiinteistotiedot-ja-niiden-hankinta
Fastighetsregisterkartan behövs exempelvis i samband med planering av markanvändning, planläggning, fastighetsköp, skogsplanering, som baskarta för andra uppgifter och i karttjänster.

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.
