Historical Outline of Cadastral
System:
|

The modern Swedish cadastre is based on cadastral books from 1530,
established for taxation purposes by the king. These books list
real properties village by village and give every unit a number
in the village. This numbering system is still used for designation
of real properties. During the 17th century these books were complemented
by village cadastral maps, showing all real parcels in the village.
The purpose of these maps was mainly to improve the taxation of
land and make it more just and equal, by surveying the area and
value of each land parcel. In order to carry out this task, Lantmäteriet
(National Land Survey) was created 1628 as a governmental organisation.
Land registration (land titles) have been confirmed since beginning
of history by local courts in order to make it known that a property
has changed ownership. Written documents are available from medieval
time. 1875 a title registration system was introduced. Court proceedings
was compared to the cadastral books and maps and a special registry
was established, the real property register in order to give one
definition of a real property and a designation to this unit.
The title registration system was based on the real property register
and the description of the property in the real property register.
The real property register was established during a 20-year period
from 1910-1930.
In 1930ties a work to establish a comprehensive and coherent
national map in one national geodetic system was started. From
the beginning, these maps were based on aerial photography, photo
mosaics and later orthophotos. The maps were named economic maps
and were produced in scales from 1:5,000-1:20,000. Cadastral boundaries
were transferred from the old village maps to the new system by
mainly photo interpretation of the boundaries and comparison with
the old maps. There were no attempts to calculate new areas for
the property units. This mapping programme was finished 1978 and
is now maintained and complemented with land use plans, regulation
and other features of importance for land use rights.
Another important development is that the original cadastral
books with its division of the village into real properties also
started (around 1600) to be used for recording of the population
(birth, death and place of living) by the church, which at that
time was a State Church. This recording has been maintained since
then and today been taken over by the Tax Authority. In this way
all people living in Sweden are connected to a real property in
a continuously updated census. This is today a very important
possibility for use of land information and social data for public
and private planning and administration. The church books are
a very interesting source for genealogical research.
In 1960ies a governmental investigation started to look into
the question on how the books in the real property register could
be modernised. It came out with the proposal to computerise the
real property register. One of the main advantages was seen in
the possibility to combine information in the real property register
with the population register through the property designation
and thus make spatial analysis to support physical and economical
planning. For this purpose each real property was assigned a centroïd
coordinate in the national system. This was actually one of the
pioneer works, which later led to the development of Geographic
Information Systems, GIS. The decision to computerise the real
property register was taken 1968 and the land registry 1970. The
system was developed and the first county started with legal force
1975. The system was completed for the whole of Sweden in 1995.
The computerisation of cadastral maps has been made in two ways.
First, cadastral parcels were digitised from the economic map,
which now is totally digital and has changed name to the real
property map. Secondly, surveys of each parcel and parcel (cadastral)
maps have been transferred to more accurate cadastral data bases,
which have been integrated with the land information system. This
process has included many problems in order to link various local
geodetic systems into one national system.
