In Article 24 of the regulations governing geographic names (GeoNV), the Federal Office of Topography (swisstopo) is commissioned to establish, administer and publish the new of...
The Topographische Atlas der Schweiz was published over the period from 1870 to 1926, initially under the leadership of Colonel Hermann Siegfried. This was the first complete de...
Instead of providing a user with the new reference frame LV95 in a classical manner with site descriptions and coordinates, it is also conceivable to provide LV95 using permanen...
Swiss geoid model in the version of 2004 (CHGeo2004) in the reference system ETRS89. It forms the zero reference surface (approximated mean sea level) for height determination a...
The National Map 1:1 million is a small-scale topographic map giving an overview of Central Europe: Switzerland and its neighbours from Lyons to Salzburg and from Strasbourg to ...
All spatial data is based on measurement points. It is recommended to use the so-called fixed control points for all technical works which need reliable and accurate position me...
swissBOUNDARIES3D contains all administrative units and national boundaries of Switzerland and the Principality of Liechtenstein in vector form. The product is based on an optim...
The National Map 1:500,000 is a topographic map giving an overview of Switzerland. The map content is updated periodically in a regular six-year cycle according to a revision pl...
Swiss geoid model in the version of 2004 (CHGeo2004) in the reference system CH1903. It forms the zero reference surface (approximated mean sea level) for height determination a...
The Federal Office for the Environment (FOEN) is the body within the Swiss Geological Survey responsible for hydrogeology. The 1:500,000 Hydrogeological Map forms part of the Ge...
The 1:200'000 geotechnical map (GK200) shows the subsurface strata classified according to lithological-petrographic criteria. The legend is designed to represent the technical ...
The Bouguer anomalies for Switzerland are shown on 22 sheets. A Bouguer anomaly is the difference between the gravity measured at a particular point on the Earth's surface and t...
Gravitational acceleration or gravity depends on the location of the measuring point and the mass distribution in the subsurface structure. A Bouguer anomaly is the difference b...
The 1:500,000 Geological Map of Switzerland covers the whole of Switzerland and adjoining parts of neighbouring countries. It gives an overview of the distribution of the upperm...
Geological mapping of the whole country based on the Dufour Map of Switzerland. Comprised of eight sheets, published between 1942 and 1964, the General Geological Map of Switzer...
The Tectonic Map of Switzerland (GK500-Tekto) covers the whole of Switzerland and adjoining parts of neighbouring countries. It shows the large-scale structural and tectonic uni...
The overall magnetisation of a rock consists of induced magnetisation caused by the Earth's magnetic field and of remanent magnetisation acquired by the rock during its formatio...
Geomagnetic maps are the result of measurements of total intensity, declination and inclination. The inclination is the angle formed by the orientation of the magnetic field rel...
Isostatic anomalies can be deduced using the Pratt or Airy hypothesis. These anomalies correspond to the static flotation of the Earth’s crust in the upper mantle. The deviation...
