Tectonic Map of Switzerland 1:500000

The Tectonic Map of Switzerland (TK500) depicts the tectonic units and structural elements of the entire Swiss territory and neighboring regions. These units group together rocks with a common geodynamic history and are separated from one another by tectonic discontinuities. Within some units, a distinction has been made between crystalline basement and one or more successive series of sedimentary cover. Units are grouped into structural domains separated by major tectonic discontinuities. Units and subunits can be located by entering their name in the search field, like some structural lines (not all have names). The current map (4th edition, 2024) is accompanied by an <a href="https://www.geocat.ch/geonetwork/srv/api/records/a4cdef47-505e-41ab-b6a7-ad5b92d80e41/attachments/TK500-ERL.pdf?approved=true" target="_blank">explanatory note</a> providing a brief definition of each unit.

A second enclosure contains a series of <a href="https://www.geocat.ch/geonetwork/srv/api/records/a4cdef47-505e-41ab-b6a7-ad5b92d80e41/attachments/TK500_Plate-III_Paleogeography.pdf?approved=true" target="_blank">paleogeographic diagrams</a>, from the Middle Jurassic (170 Ma) to the present day, showing the evolution of spatial relationships between the different tectonic domains covered by the map.
swissEO S2-SR: Optical satellite data (Sentinel-2) v200

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.
Accommodations winter

The winter accommodations are part of the national maps with snow sports theme for Switzerland and adjacent parts of its neighbouring countries. The data set is produced in collaboration with the Swiss Alpine Club SAC and updated annually. Winter accommodations are open during the snow sports season, are located on existing snow sports routes or in the immediate vicinity, in valley locations for crossings or in starting or finishing locations of a tour that are difficult to reach. Accommodations in ski resorts are not shown. 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 information. Detailed tour planning is highly recommended. Further information on most winter accommodation can be found on the SAC route portal or the SAC-CAS app: <a href="https://www.sac-cas.ch/en/" target="_blank">https://www.sac-cas.ch/en/</a>.

The National Map 1:1 million (grey) is a small-scale topographic map giving an overview of Central Europe: Switzerland and its neighbours from Lyons to Salzburg and from Strasbourg to Genoa on a handy overview map (Paris, Vienna, Frankfurt and Marseille on one sheet). The National Map 1:1 million (grey) is published in digital format as the Swiss Map Raster and is also available as WMS or WMTS geoservice.
Transition of reference frames LV03 - LV95: Triangular network (CHENyx06 and FINELTRA LV)

The triangular network of the national survey (FINELTRA-LV) was completed in the 90's and has permitted to transform geodata from LV03 to LV95 and vice versa with an accuracy of about a decimetre. This network has been condensed systematically by the cantons in recent years, and then assembled by swisstopo in 2006 in a dataset named CHENyx06. With CHENyx06, geodata can be transformed from LV03 to LV95 and vice versa with an average accuracy of about 2 cm. The triangular network has been established from pass points called TSP (“Transformationsstützpunkte” in german). TSP are very accurately, in both reference frames LV03 and LV95, measured surveying points. TSP points of categories 1 and 2 are available from the “Control point data service “ (FPDS “Fixpunkt-Datenservice“ in german) or on the "Horizontal control points" layer in the federal geoportal map.geo.admin.ch. Information about other TSP points are provided by the cantons.
Aeromagnetic Map of the Swiss Plateau and the Jura Mountains

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 special aeromagnetic map shows the total intensity of the magnetic field (epoch 1980.5) measured at an altitude of 1829 m a.s.l. – Paper map: total field, E. KLINGELE, 1982. – Vector map: online version, aeromagnetic residual anomalies (removal of regional trends), E. KLINGELE, 2009.

swissTLMRegio Hydrography

The topic Hydrography contains the different features connected to water. It consists of 6 feature classes and one table. The lines of "FlowingWater" and "StagnantWater" and the points of "GWK_FW_Node" are connected with 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. In collaboration with the Federal Office for Water and Geology (BWG), the edges and nodes in Switzerland were structured and addressed according to GEWISS (the Swiss Water Information System). For this reason, the so called GEWISS-Attributes were integrated. A Feature Class with information on waterfalls, locks and other objects was integrated into this topic.
Hydrogeological Map of Switzerland: Groundwater Resources 1:500000

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 GeoMaps series (GK500) and is divided into two sheets. The first (GK500-Hydro) represents the various groundwater resources in Switzerland and their productiveness. The second (GK500-Hydro_Vul) shows the vulnerability of the groundwater resources to the risk of pollution. The groundwater resources sheet also indicates the type of groundwater aquifer (karstic, jointed or unconsolidated rock), the most important springs and groundwater catchments as well as hydrodynamic information about the infiltration and exfiltration areas. The two sheets were originally published as Tables 8.6 and 8.7 of the Hydrological Atlas of Switzerland HADES (FOEN, 2004 and 2007).
swissEO VHI: state of vegetation health

Map of vegetation condition based on the VHI (Vegetation Health Index), which reflects the current state of vegetation in relation to historical data 1991-2020. The index is based on satellite data (Meteosat, Landsat 5,7,8, and Sentinel-2) of different spatial resolutions, aggregated to ten and thirty metres respectively. The VHI consists of two components: one part (VCI - Vegetation Condition Index) represents the local biophysical conditions of the vegetation, and the other part (TCI - Thermal Condition Index) characterizes the climatic conditions (temperature). Both components depict the current situation in relation to a reference period. The combined VHI is used to assess drought and other disturbances or stress factors— the lower the value, the greater the stress and its impact on vegetation. Values from 100 down to 60 indicate excellent vegetation condition, values up to 50 are good, and values up to 40 are normal. Below 40, the vegetation shows signs of stress, up to 30 it is lightly stressed, up to 20 stressed, up to 10 severely stressed and values below 10 indicate an extremely stressed vegetation condition. The entire vegetation area is shown on the map view to provide a complete overview of the regional vegetation status. The dataset was developed in collaboration with MeteoSwiss for the federal drought portal. Contains modified Copernicus Sentinel data.
Switzerland During the Last Glacial Maximum (LGM) 1:500000

Other industrial minerals

This dataset shows the sites where industrial minerals have been located or mined in the past in Switzerland. Thanks to their specific chemical and/or physical properties, industrial minerals are used in various industrial manufacturing processes. Gypsum and salt are common industrial minerals mined and processed in Switzerland today. Because of their importance, they are presented separately in the Geoportal map viewer (see the <a href="https://map.geo.admin.ch/?layers=ch.swisstopo.geologie-rohstoffe-gips_abbau_verarbeitung&topic=georessourcen" target="_blank">Gypsum</a> and <a href="https://map.geo.admin.ch/?layers=ch.swisstopo.geologie-rohstoffe-salz_abbau_verarbeitung&topic=georessourcen" target="_blank">Salt</a> datasets). Some industrial minerals are currently classified as Critical Raw Materials (CRMs) in the <a href="https://eur-lex.europa.eu/eli/reg/2024/1252/oj/eng" target="_blank">European Union</a> and some are <a href="https://api3.geo.admin.ch/featureattachments/ch.swisstopo.geologie-rohstoffe-industrieminerale/pdf/IRENA_NUPI_2024_Ranking_critical_materials_for_the_energy%20transition.pdf" target="_blank">considered absolutely essential</a> for the energy transition. Several sites listed in this dataset indicate a mineralization that may contain one or more critical raw materials. The concentration and volume of these mineralizations are essentially unknown or insignificant. Based on current knowledge, a commercial exploitation of these occurrences does not appear feasible. Gypsum and salt aside, no industrial minerals are currently being mined commercially. Users are invited to consult the report <a href="https://www.aramis.admin.ch/Texte/?ProjectID=57845" target="_blank">Critical Raw Materials in Switzerland – A Review</a> for a more detailed geological overview of the situation regarding CRMs. Other critical raw materials are shown in the <a href="https://map.geo.admin.ch/?layers=ch.swisstopo.geologie-rohstoffe-vererzungen&topic=georessourcen" target="_blank">Metallic raw materials</a> dataset. In case it is desired to develop a mining site, it is essential to conduct a detailed geological investigation on the location of interest. This dataset is periodically updated and does not claim to be exhaustive.

Geotopes in Switzerland

Geotopes are geoscientific natural monuments. Geotopes that represent geological history show the development of the landscape, the climate and life, the formation and disappearance of mountains and the origins of rocks. Other geotopes shed light on the processes taking place on the Earth's surface and in the Earth's interior. They also include the hidden world of caves and groundwater. A final group of geotopes consists of active elements of the landscape, such as scree slopes, flood plains and groundwater springs. Geotopes are spatially limited parts of the mineral, uninhabited Earth (geosphere). Depending on their thematic content, they can be an individual occurrence in one location or an entire portion of the landscape. They must be protected against influences that can impair their substance, structure, form or natural development. The geotopes listed here are of national importance and are taken from the informal inventory of the Swiss geotope working group (Swiss Academy of Sciences SCNAT). The inventory is not based on a systematic survey and, therefore, does not claim to be complete. Sources: Felber, M. (1999): Inventar der Geotope nationaler Bedeutung. Geologia Insubrica 4/1.

Aerial Images swisstopo infrared

The aerial imagery catalogue of swisstopo includes several hundred thousand analogue aerial photographs (in colour, infrared, or black and white). They are represented by the centre-image coordinates, the image footprint, as well as by their metadata (including orientation elements, if available). If already digitised, the images can be downloaded and viewed in full resolution. Missing scans of the images are gradually being added and made directly available. As part of the Sanasilva programme to record the health of forests, lines were engraved directly onto some original aerial photographs. According to the commissioning party at the time, these markings were used in the evaluation to distinguish between different tree populations – i.e. populations of the same age and/or with the same species composition.
swissSURFACE3D Raster monodirectional hillshade

The hillshade is derived from the digital elevation model swissSURFACE3D Raster. It illustrates the surface relief of Switzerland and the Principality of Liechtenstein. A hillshade is derived from the elevation model by calculating the exposure of the surface to sunlight at a certain or several angles. The monodirectional swissSURFACE3D Raster hillshade is generated using a northwestern sun position as light source.
