The 0 000 Topographic Map of Switzerland (Dufour Map) was the first official series of maps that encompassed the whole of Switzerland.
It was published in the period from 1845 to 1865 and thus coincides with the creation of the modern Swiss Confederation.
Six cantons as well as the Principality of Liechtenstein have delegated this task to the Federal Directorate for Cadastral Surveying, technical agency of the Confederation. Besides the traditional national reference systems, there is a European reference system ETRS89.
The connection of national reference systems to global, terrestrial reference systems by means of geodetic measuring methods results in only a limited accuracy.
The modern (local) reference systems, however, distinguish themselves by a precisely defined link to global systems, allowing absolute positioning within a cm.
In the field of engineering surveying, swisstopo provides a broad variety of services, ranging from the development of fundamental GNSS networks and the operation of permanent GNSS stations, through to the analysis of deformations in dams, gravity calculations and gyroscopic measurements.
As a user you can directly access geographic information, data and services of the federal government free of charge. Why is geology so important when it comes to energy production?
The history of our planet is full of secrets and fascinating facts.
Basic geological data in digital form are primarily used for carrying out modern geological analyses and exploring the underground.
Here the focus is on demanding surveying tasks calling for the highest possible degree of accuracy and reliability.
The fundamental station Zimmerwald is operated jointly by swisstopo and the Astronomical Institute at the University of Bern.
Embark on a voyage through time with swisstopo’s topographic maps and travel through almost 175 years of Swiss cartographical history, even as far back as the time before the Swiss Confederation was founded. When it comes to the sustainable management of our living space, historical maps and digital 3D models are just as important bases as geological, geophysical and geotechnical datasets.
The Geo Cover vector dataset depicts all of Switzerland on the basis of the ,000 map sheets.
It often determines our life and actions without being noticed.
