Information about the PLR Cadastre from a single source
You can now obtain information about the PLR Cadastre from a single source.

The existing cadastre was exclusively based on civil law. A project to introduce a new Cadastre of Public-law Restrictions on Landownership (PLR-cadastre) is launched in 2009.

Implementation of the first state examination, brought about by new regulations governing licensed land surveyors.

2008

Entry into force of the Federal Geoinformation Act. Switzerland is one of the first countries in Europe to introduce modern geoinformation legislation which will meet its future needs.

At the same time, introduction of a register of licensed land surveyors, which makes a clear distinction between educational diplomas, professional practice and disciplinary measures.

2004

In accordance with the new Article 75a in the Federal Constitution, the national land survey becomes the responsibility of the federal government, which is also responsible for issuing regulations governing the cadastral survey.

1995

Introduction of a satellite-based network, the Swiss National Land Survey LV95, which now comprises 210 specially selected permanent control points.

1993

With the entry into force of the new Ordinance on Official Cadastral Surveying and the Technical Ordinance on Official Cadastral Surveying, digital databases begin to replace conventional graphic media.

1990

Positioning with the aid of satellites (GNSS) is also used in cadastral surveying.
Global navigation satellite systems (GNSS)

Introduction of GPS as a new satellite-based method in cadastral surveying.

1989-1999

Between 1989 and 1999, the pilot project in the canton of Nidwalden demonstrated that cadastral surveying in digital form can be carried out for an entire canton.

1983

Initiation of the «cadastral survey reform» project in 1983 with the aim of providing improved services to the government, the economy and the general public. This move results in the introduction of federal ordinances in which the content of the cadastral survey is brought into line with the new technological developments.

1981

The severe delay in the 1923 cadastral surveying programme, as well as the shift in society towards digital technology, mean that new cadastral surveying concepts are required. In 1981 the Federal Council introduces its programme for the completion of the cadastral survey in Switzerland (Programme 2000).

1965

Survey data increasingly processed electronically. At the beginning of the 1970s, introduction of electronic distance measurement and, before long, use of automated data processing in cadastral surveying.

1940

Use of mechanical desktop calculators and natural logarithms of the trigonometric functions for determining coordinates.

1929

Surveying aircraft
Surveying aircraft: B.F.W. M 18c (Bavarian Aircraft Plant in Augsburg)

Acquisition by the Federal Department of Justice and Police of the first surveying aircraft (a B.F.W. M 18c manufactured by Bayrische Flugzeugwerke, Augsburg) equipped with a camera for taking aerial photographs for surveying purposes.

Introduction of the use of aluminium plates as a low-distortion graphic medium.

1927

 double-image tachymeter
Reduced double-image tachymeter: Bosshardt-Zeiss and Kern & Cie,. Aarau

Introduction of the polar coordinates method with optical distance measurement by means of «reduced double-image tachymeters». 

1925

Production of the first series of aerial images recorded on a trial basis using military aircraft, with subsequent analysis of the results in Munich.

1923-1925

measurement camera
Aircraft measurement camera: Heinrich Wild Geodetic Instruments Heerbrugg

Introduction of the use of terrestrial photogrammetry (measurements carried out from the ground with the aid of photographs) at the beginning of the 1920s: these images are used for producing accurate terrain maps in the mountain regions.

1923

In accordance with the Resolution of the Federal Council dated 12 November 1923 on the general plan relating to the implementation of the cadastral survey (1923 cadastral surveying programme), the aim is for the cadastral survey to be completed by the end of 1976. However, the programme is severely delayed due to the promotion of land consolidation called for by the Federal Council in 1918 and the consequences of World War II.

1919

With the introduction of two Instructions in 1919 – one governing the 4th order triangulation and the other governing cadastral surveying and delimitation – legal provisions specifying the method and form of surveying enter into force.

1912

Seal

Together with the introduction of the Swiss Civil Code it is decided to also introduce a federal land registry. This means that the federal government is now responsible for cadastral surveying, though its implementation is assigned to the cantons. The federal government remains the supervisory authority and assumes responsibility for a large portion of the development costs. Since then, land ownership has been secured via entry in the land register.

1910

The form and extent of the financial contribution by the federal government towards the cost of cadastral surveying are regulated by a federal resolution dated 13 April 1910.

1903

The first Swiss geodetic network (1st to 3rd order triangulation) is established in the period from 1903 to approximately 1925. It is based on around 5,000 permanent control points of the Swiss National Land Survey (LV03). For about 100 years, this forms the geodetic reference framework for surveying activities in Switzerland.
