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...
During fieldwork in the official cadastral survey, a local adaptation must be made or proof must be provided that this is not needed. In low distortion areas, a local adaptation...
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...
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...
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...
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 ...
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 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...
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...
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...
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 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 declination describes the angle formed between magnetic and geographic north...
Geomagnetic maps are the result of measurements of total intensity, declination and inclination. The geomagnetic field is defined by a vector, which isrepresented in terms of it...
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...
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...
The GeoCover datasets are available according to the sheet division of the National Maps 1:25 000. The «Division GeoCover» shows the perimeter, number and name of each map sheet.
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...
The geothermal map shows the thermal energy that is produced in the subsurface and traverses the Earth's surface within an area of 1 m2. The heat itself is released in the Earth...
