Municipal boundaries - journey through time

The layer municipal boundaries constitute the administrative borders of the municipalities of Switzerland and the principality of Liechtenstein. The municipality is the smallest administrative unit. By default, the current status of municipal boundaries is displayed. With the historical data representation tool - called " journey through time - the evolution of municipal boundaries from 1850 to the present day is interactive. When a year prior to the current status is selected, the status of municipal boundaries on the first of January is displayed. For the current status, mergers of municipalities during the year are included. Two data sources have been used to generate this layer: "Municipal boundaries: time series since 1850s" from the Swiss Federal Statistical Office for the period 1850 - 2015 and swissBOUNDARIES3D from the Swiss Federal Office of Topography for the period 2016 to the present.
Gravimetric Map of Switzerland (Bouguer Anomalies) 1:500000

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 between the gravity measured at a particular point on the Earth's surface and the gravity value expected at the same point for an Earth model with a homogeneous crust. Bouguer anomalies are calculated using the International Gravity Formula of 1967. Topographic effects are taken into account using a constant density of 2670 kg/m3 to a depth of 167 km (Hayford Zone O2). The map highlights, on the one hand, the regional negative gravity anomalies along the Alps and, on the other hand, the positive anomalies in the Sesia-Finero zone, which signify a mass excess in the Earth's interior. By E. Klingelé & R. Olivier, 1979. New edition: R. Olivier, B. Dumont & E. Klingelé, 2008.
Crushed-rock aggregates

This dataset shows the extraction and production sites of crushed-rock aggregates in Switzerland (in operation or decommissioned). Together with natural, uncrushed-rock aggregates (e.g. round gravel), crushed-rock aggregates are the most extracted and used construction raw material in Switzerland and worldwide (they are used in particular for the production of concrete). Given their importance for the national transportation infrastructure, the production and mining sites of hard rock aggregates are displayed in a dedicated dataset (<a href="https://map.geo.admin.ch/?layers=ch.swisstopo.geologie-hartsteinabbau&topic=georessourcen" target="_blank">Hartstein: Produktions- und Abbaustandorte</a>).
Ski routes

The digital ski routes contain specific information for snow sports in Switzerland and adjacent parts of its neighbouring countries. The data set is produced in collaboration with the Swiss Alpine Club SAC. The ski routes are represented as reliably as possible, checked by the cantonal hunting authorities with regard to wildlife compatibility, and updated annually. However, the actual route in the terrain depends on the current conditions. Neither the Swiss Alpine Club SAC nor the Federal Office of Topography can accept liability for the accuracy, completeness or up-to-dateness of the route information. No liability whatsoever is accepted for accidents of any kind that arise from the use of these route data. Detailed tour planning is highly recommended.

Geothermal Map of Switzerland 1:500000

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 (mW/m2). The heat flow data is calculated from the temperature gradient (average value approx. 30 K/km) and heat conductivity of the rock (average value approx. 3 W/(m·K). The heat itself is released in the Earth's crust (ca. 30 km thick) generally by radioactive decay processes. On average, the heat flow in Switzerland is around 90 mW/m2. The highest figures are found in northern Switzerland and the lowest in the Alps/Jura. Differences are caused by deep groundwater circulating in permeable rock strata. - Source: <a href="https://www.geocat.ch/geonetwork/srv/api/records/2d8174b2-8c4a-44ea-b470-cb3f216b90d1/attachments/Beitrag_GP_030_Medici-Rybach.pdf?approved=true" target="_blank">F.

swissTLMRegio Transportation public transport

The Public Transportation Topic, as part of the Transportation Topic, contains different features connected with traffic (road, railway, airports, car-ferry, ...). It consists of 12 feature classes and 3 tables. The lines and the points are related to each other according to a so called edge-node structure. Edges (lines) are connected to each other with nodes (points). Every edge has therefore exactly two nodes at its end. Edges and Nodes together build a geometric network.
Total Intensity Map of Switzerland 1:500000

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 its direction and intensity (nT). Because the Earth's magnetic field changes over time, the data in this map always relates to a specific time period. The values can be adapted using correction formulae which have experimentally determined. Paper map: G. Fischer & P.-A. Schnegg, 1979 (explanatory text on the back of the map). Vector map: 2001.
swissTLM3D Other transportations

With a high accuracy and the incorporation of a third dimension, swissTLM3D is the most extensive 3D vector data set of Switzerland. In the federal geoportal the objects of the layer "other transportations" are displayed gradually according to the different zoomlevels.
Transition of reference frames LV03 - LV95: Combined transformation accuracy map

From the combined accuracy map can be derived the accuracy of GNSS data measured, e.g. with swipos positioning service, in LV03 (with real-time-FINELTRA) or LV95, compared to national survey and cadastral data (frame of reference). Therefore, it is for instance possible to avoid a local adjustment in the low distortion areas. For further information about the use of the combined accuracy map please follow below the "link to the detail description".

swissBATHY3D Hillshade : Bathymetric data

This representation is derived from the swissBATHY3D data and allows the visualization of the depth and lakebed relief of Swiss lakes. A hillshade is derived from the elevation model by calculating the exposure of the surface to sunlight at a certain angle. The calculated angle of the sun for the swissBATHY3D Hillshade is at azimuth 315° (northwest), at a vertical angle of 45°.
swissEO NDVIz: Anomalie of NDVI

Map of the NDVI anomaly (Normalized Difference Vegetation Index), which represents vegetation vitality by comparing the current state with the reference period 1991–2020. The values are based on satellite data (Landsat 5, 7, 8 and Sentinel-2) and, in the final product, have a spatial resolution of ten metres. The index anomaly indicates a change in the density and/or chlorophyll content ("green") of vegetation. NDVI increases may result from growth and increased productivity, whereas NDVI decreases are usually the result of management or natural disturbances (storm damage, drought, insect damage, etc.). The anomaly is represented by the Z-Score. The further the current state deviates from the normal state of the reference period, the larger the Z-Score. For example, a Z-Score of +1 means that vegetation is more vital than in 68% of the comparison years, while a value of +2 already indicates higher vitality than in 95% of the comparison years. This dataset was developed in collaboration with BFH-HAFL and the Federal Office for the Environment (FOEN) for waldmonitoring.ch and the federal drought portal. Contains modified Copernicus Sentinel data.
Territorial limit points NS

The “Territorial limit points NS” dataset contains the points marking the vertices of the national border (Territorial limit NS) and is managed by the national survey. These points delimit both the territory of the Swiss Confederation with respect to foreign countries and the external boundaries of Swiss cantons, districts, municipalities, and properties. Managed in the official survey as boundary points (geodata model DMAV_Grundstuecke_V1_0), they are made available as a service. The data are provided without elevation information.
Thermal waters

This dataset contains an overview of groundwater in Switzerland that have been heated by geothermal energy. The increased temperature of thermal groundwater results from the interaction with the surrounding rock as it circulates to greater depths in the earth's crust. The temperature of non-deep, non-thermal groundwater, on the other hand, is mainly influenced by the atmosphere and exhibits seasonal fluctuations over the course of a year. In this dataset, groundwater is considered to be thermal if the water temperature is constantly more than 5°C above the local average annual air temperature. The dataset is subdivided into three main categories, which are based on the type of water discharge/inflow: 1) spring water, 2) tunnel water and 3) groundwater accessed by drilling. In the course of circulation through the geological subsurface, groundwater takes on a characteristic chemical signature through water-rock interactions. This signature is represented here by the chemical water type, degree of mineralization, pH and electrical conductivity. Some of the measured values may be subject to greater uncertainties as a result of contamination with technical waters (e.g. drilling fluids) and/or the atmosphere (e.g. gas exchange) or methodological causes. The significance and uncertainties of the individual attributes are explained in more detail in the <a href="https://www.geocat.ch/geonetwork/srv/api/records/04fb057a-4c46-4d6d-8a64-8003df749762/attachments/Objektkatalog_Layer_Thermale_W%C3%A4sser_v3.2_Juni2025.pdf?approved=true" target="_blank">object catalog</a>. The dataset does not claim to be complete. For information on the individual measured values, please contact the data provider.
VECTOR25 Hydrographic network GWN07

The layer "Hydrographic network" consists of a directionally oriented line network connected to each other with nodes, and of a table without geometry. Those features which are in Switzerland and the Principality of Liechtenstein form the basis for the Swiss Water Information System (GEWISS). GEWISS is managed by the Federal Office for the Environment (FOEN). The layer Hydrographic network has been completely revised within the project GWN07. The release 2007 of VECTOR25 gwn is published as reference.
swissEO S2-SR: Optical satellite data (Sentinel-2)

Optical satellite data (Sentinel-2) which, among other things, show the reflectances of the land surface for the four channels Red, Green, Blue and near Infrared in a spatial resolution of 10 metres. Switzerland is mapped by four orbits of the satellite overflight. The overlapping orbits result in a complete image of Switzerland approximately every three to five days, but the usefulness of the data is heavily dependent on meteorological conditions, as the imaging sensor cannot see through clouds. In addition to the already applied localisation of the data, a co-registration of the data optimised for Switzerland is applied for a sub-pixel positional accuracy and the data is delivered in a uniform projection. Also included are optimised quality layers with masks for clouds (and cloud shadows) and topographic shadows. Contains modified Copernicus Sentinel data.
Planimetric control Points LFP1 (National Survey)

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 measurements. A planimetric fixed control point ("Lagefixpunkte" in german) is a surveyed point permanently marked with a stone monument or a bolt (sometimes covered by a manhole) with known coordinates and potentially height. The Swiss national land survey is responsible for the first category of planimetric fixed control points. There are several types of those: * Planimetric fixed points of the first categorie LFP1 provide the reference framework for all survey work in Switzerland. LV03 coordinates from historical fixed control points have been established by triangulation at the beginning of the 20th century. * TSP1 pass points (“Transformationsstützpunkte” in german) are very accurately measured surveying points in both reference frames LV03 and LV95, . * EUREF points are planimetric fixed points from the European GNSS reference network EUREF (European Reference Frame). * LV95 points are planimetric fixed points used as basis for the new reference frame LV95. Their coordinates have been with GNSS precisely measured. Since a planimetric fixed points can be simultaneously from different types, the symbols of this layer can be overlayed.
Geoid model CHGeo2004 in ETRS89

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 and serves for the transformation between ellipsoidal heights and orthometric heights (LHN95). The geoid heights are stored in a regular 30 x 30 seconds grid and are interpolated by the biquadratic method. The model is available in various reference systems and data formats.
Slope classes over 30 degrees

Derivate representation of the digital terrain model swissALTI3D and models from France, Italy, Austria and Germany, which allows for the identification of inclinations over 30°. According to the recommendation of the Institute for Snow and Avalanche Research SLF the slopes are categorized into 4 classes. They were calculated from a combined digital terrain with a resolution of 10m made up from swissALTI3D for Switzerland and Liechtenstein, RGE ALTI for France, TINITALY for Italy, DGM10 for Austria, DGM1 for Bavaria and EU-DEM for Baden-Württemberg. The precision of the inclination values in the transistional area between the different base models cannot be guaranteed. Liability claims for the representation of gradients over 30° cannot be asserted.
Switzerland During the Last Glacial Maximum (LGM) 1:500000 (vector map)

Aeromagnetic Map of Switzerland 1:500000

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 formation. Regional or local differences in the geomagnetic field on the basis of a global model, referred to as anomalies, are measured from aircraft. These anomalies can make it possible to identify the geological and tectonic structures and the presence of mineral deposits. The Aeromagnetic Map of Switzerland shows the total intensity of the magnetic field (epoch 1981.5) measured at an altitude of 5000 m a.s.l. - Paper map: total field, E.
