New tasks and Topographic Landscape Model

Changes and innovation define the recent past and present at swisstopo: the Swiss Federal Office’s fields of activity are expanding, the legal bases are being adapted to the needs of the day and the Topographic Landscape Model (TLM) is profoundly changing the production of geodata.

Switzerland in 3D: The Topographic Landscape Model

A Widened Scope of Activity

The latest phase in the history of the Office was the inclusion of the Swiss Federal Directorate of Cadastral Surveying (1999) and the Swiss Geological Survey (2006) within swisstopo; the Coordination, Geo-Information and Services (COGIS) Division was set up in 2000.

Federal Act on Geoinformation

In 2008, the Swiss Federal Geoinformation Act came into force. It aims to provide current geodata relating to the entire Swiss territory promptly, easily and sustainably for the administration, economy and population to use.

This legal mandate is expressed in the Swiss Federal Geoportal, established in 2009/2010. It provides the general public with relevant geoinformation from many Federal Offices. The coordinates of the new national survey (LV95) were used as a geodetic basis for this, replacing the 1903 national coordinates system (LV03) in 2007.

Since 2018, Switzerland can also be viewed in 3D on the Swiss Federal Geoportal.

The Topographic Landscape Model

In parallel to the structural changes, swisstopo’s work processes also changed. Digital geodata was no longer derived from the analogue maps but from the digital models.

The impetus for this transformation occurred in 2001 when digital cartography definitively replaced negative scribing on glass, which had been introduced in 1953. However, this relationship between maps and digital models was only applied in the Topographic Landscape Model, operated since 2008.

The 3D geodatabase is directly based on the data drawn from the topographical photos.

New National Maps

The “New National Maps” have been created on the basis of data from the digital cartographic models (DCM) since 2011, which are based, in turn, on the TLM. This increases flexibility, making it possible to optimise the new National Maps’ representation. This mainly makes them easier to read and adapts them to new customer requirements.

In 2016, the new flexibility of map production through TLM and DCM was made particularly clear: the National Maps were published for the first time to a scale of 1:10,000 and solely in digital form.

2001: Definitive replacement of negative scribing

As of the beginning of 2001, definitive replacement of the negative scribing process by digital cartography. Publication of the last map sheet (no. 39, Flüelapass) to be updated in analogue form.

2003: Federal Council adopts concept for implementation of geodata infrastructure

Federal Council adopts the concept for the implementation of the federal geoinformation strategy formulated by COGIS. The aim of this concept is to develop a national geodata infrastructure. This results in a paradigm shift at swisstopo: the focus is now on benefits for the economy instead of on business considerations. 

2004: Realisation of nationwide SWISSIMAGE coverage

Realisation of planned complete coverage of SWISSIMAGE. This means that every square metre of the country is now depicted in the form of a homogeneous orthophoto mosaic with a ground pixel resolution of 50 centimetres. 

2005: Acquisition of new aerial image camera (ADS40)

Acquisition of a new digital aerial image camera (ADS40), immediately available for updating the SWISSIMAGE orthophoto mosaic as well as the national maps, following the changeover from analytical to digital photogrammetry for the topographic survey. Introduction of new flight schedules for recording aerial images for SWISSIMAGE with the ADS40 in order to take account of the new ground pixel resolutions of 25 centimetres (central plain, Jura, Alpine valleys) and 50 centimetres (mountain regions). 

2006: swisstopo takes over management of Mont Terri research project

swisstopo takes over management of the Mont Terri (canton of Jura) research programme and is now operator of the rock laboratory. Mont Terri is an international research project aimed at determining the hydrogeological, geochemical and geotechnical characteristics of an opalinus clay formation.

2010: Geodata now available to everyone

Thanks to the implementation of the Federal Geoinformation Act, geodata are now available to everyone. swisstopo assists with the introduction of the federal geoportal. "Excellence publique" prize awarded to geo.admin.ch. Federal geoportal is the first unit of the Federal Administration to use cloud computing.

2010: Publication of a new geological map

 Swiss Geological Survey publishes a new map in its GeoMaps 500 series: "Switzerland during the last glacial maximum".

2010: Production of three new 3D datasets

Production of three new 3D datasets from the topographic landscape model: swissBUILDINGS3D (building volume excluding roof shape), SWISSIMAGE FCIR (false-colour infrared orthophotos) and swissBOUNDARIES3D (administrative units and boundaries in vector form), replacing GG25. 

2012: New coordinates for the national maps

New coordinates for the national maps.In order to clearly distinguish between the old and new coordinates, a seventh digit has been prefixed to the original six-digit coordinates: 1 for the north-south direction and 2 for the east-west direction. 

2013: High-resolution digital height model now covers the entire country

High-resolution digital height model (swissALTI3D) now covers the entire country, including regions higher than 2,000 metres above sea level. SwissMeteo made a major contribution towards the creation of this model (e.g. by enabling climate observation).
