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...
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 ETRS89. It forms the zero reference surface (approximated mean sea level) for height determination a...
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...
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 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...
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 Map Vector 500 is the Swiss national 1:500,000 scale map in vector format. It includes the railway network, all highways, semi-highways, transit and link roads, a highly s...
The digital height model DHM25 / 200 is a data set representing the three-dimensional form of the earth's surface. It is a height matrix with a 200-m grid. It has been resampled...
Swiss Map Vector 1000 is the Swiss national 1:1,000,000 scale map in vector format. It provides a clear depiction of the main traffic axes, residential areas, bodies of water, s...
The 1:200'000 map of mineral resources (RK200) classifies the subsurface strata according to geochemical criteria. The map is overlaid with point data showing the occurrence of ...
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...
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 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...
Die amtliche Vermessung (AV) beschreibt die Lage, die Form und den Inhalt eines Grundstückes. Die digitalen AV-Daten sind in mehreren thematischen Informationsebenen gegliedert,...
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...
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 inclination is the angle formed by the orientation of the magnetic field rel...
