Electricity Transmission Lines sectoral plan

The Electricity Transmission Lines sectoral plan is an overlying federal government planning and co-ordination instrument for the expansion and further development of the high-voltage (220 to 380 kV) transmission lines for general electricity supply, and the 132 kV transmission lines of Swiss Federal Railways for the operation of its network. The Swiss Federal Office of Energy (SFOE) is responsible for this sectoral plan in co-operation with the Swiss Federal Office for Spatial Development (ARE).
Suitability of roofs for the use of solar energy

Solar energy that reaches the earth’s surface can be utilised with the aid of the two established solar technologies, photovoltaics (electricity) and solar thermal energy, for the production of renewable energy. The potential of solar electricity is considerable: by 2050, around 20 percent of the current level of electricity demand could be met through the use of photovoltaics. Solar thermal energy is an attractive option for the production of hot water and heat thanks to the existence of standardised systems. From the suitability map the degree of suitability of a particular roof for the use of solar energy can be deduced, as well as the anticipated yield. The calculations are based on a simulation of the path of the sun throughout the year, and the amount of sunlight that falls on each roof surface.
Sustainable potential of woody biomass resources for bioenergy in Switzerland at the municipality level

Biomass is a renewable resource for energy which can be transformed into several forms of energy: heat, electricity, biogas or liquid fuels. Woody types of biomass were investigated using methodically comparable approaches: forest wood, wood from landscape maintenance, waste wood and industrial wood residues. Within the implementation of the energy strategy 2050 the Swiss government foresees a massive increase in the share of renewable energy. The Swiss Competence Center for Energy Research (SCCER) Biosweet (Biomass for Swiss Energy Future) seeks solutions to the technical, social and political challenges posed by the Energy Transition with regard to biomass. The Swiss Federal Institute for Forest, Snow and Landscape Research WSL quantified and localised the potential of important biomass resources in Switzerland, particularly with regard to their sustainable availability. The results are useful as a basis for identifying promising biomass-use pathways and the best sites for their implementation. Data (https://www.envidat.ch/dataset/swiss-biomass-potentials) and a detailed report are available online (https://www.wsl.ch/de/publikationen/biomassepotenziale-der-schweiz-fuer-die-energetische-nutzung-ergebnisse-des-schweizerischen-energiek.html). This map shows the sustainable potential of woody biomass for bioenergy (maximum amount of nationally produced woody biomass that could be used, after deducting any ecological, economic, legal and political constraints) in Switzerland at the municipality level in primary energy (maximum amount of energy available in a resource without conversion) in petajoules.
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.
Sustainable potential of non-woody biomass resources for bioenergy in Switzerland at the municipality level

Biomass is a renewable resource for energy which can be transformed into several forms of energy: heat, electricity, biogas or liquid fuels. Non-woody types of biomass were investigated using methodically comparable approaches: manure, agricultural crop by-products, the organic part of household garbage, green waste, the organic residues from industrial waste and sewage sludge. Within the implementation of the energy strategy 2050 the Swiss government foresees a massive increase in the share of renewable energy. The Swiss Competence Center for Energy Research (SCCER) Biosweet (Biomass for Swiss Energy Future) seeks solutions to the technical, social and political challenges posed by the Energy Transition with regard to biomass. The Swiss Federal Institute for Forest, Snow and Landscape Research WSL quantified and localised the potential of important biomass resources in Switzerland, particularly with regard to their sustainable availability.

This map shows the sustainable potential of non-woody biomass for bioenergy (maximum amount of nationally produced non-woody biomass that could be used, after deducting any ecological, economic, legal and political constraints) in Switzerland at the municipality level in primary energy (maximum amount of energy available in a resource without conversion) in petajoules.
Residential areas under the Off-Airport Landing Ordinance (AuLaV)

Residential areas are defined in Article 2f of the Off-Airport Landing Ordinance (AuLaV; SR 748.132.3). Residential areas are defined as urban areas or groups of at least ten inhabited buildings, including the area within a radius of 100 metres. Landing in residential areas is prohibited for the following purposes:<ul> <li>Passenger transport for tourist or leisure purposes (Art. 25b AuLaV),</li> <li>Non-commercial flights (Art. 32b AuLaV),</li> <li>Training flights (Art. 34b AuLaV).</li> </ul> Off-Airport landings in residential areas for aerial work purposes must be agreed upon in advance with the competent authority under cantonal law (Art. 31 AuLaV). <br></br> The ARE's "housing estate" dataset forms the basis for identifying and presenting "residential areas" and is updated annually.
Amphibian dispersal maps

Swiss-wide map depicting the dispersal probability of the Smooth newt (Lissotriton vulgaris). Each grid cell indicates the relative probability that dispersing individuals will pass through that hectare on their way between known amphibian breeding sites. The map shows dispersal probability increasing along a scale from blue to yellow to red. These maps should be thought of as heatmaps for dispersal activity of existing populations. In practical terms, these maps also show locations where potential new amphibian breeding sites have the highest chances of being colonized. Areas with many populations in close proximity appear a darker red, reflecting the higher probability of dispersal as multiple dispersal routes between populations intersect. This feature of the maps deserves special attention. Lighter shades at the edges of the species' range do not necessarily indicate a weaker connection between populations, but rather a consequence of the lower density of breeding sites at the edges of the range. The color scale should be considered in the context of the immediate surroundings. The dispersal map was calculated using Circuitscape and is based on a landscape resistance matrix derived from the best-ranked dispersal model for each species. For details, see the attached data description. Literature: Churko G., Szerencsits E., Aldrich A., Schmidt B. R. (2024).

Distribution of organic soils in Switzerland (Agroscope 2025)

The map of organic soils in Switzerland is an update of the first map published in 2015. It provides an estimate of the distribution of (former) moorland soils that still exist today and are sufficiently humus-rich and deep to meet the criteria for organic soil.<br> The map was produced in four steps: First, soil maps, geological maps, national inventories of fens, raised bogs and transition mires, forest site maps, historical maps and documents were evaluated. Data newly available since 2015 were also included in this update. In a second step, all data sets were harmonised and incorporated into a data model allowing the various data sets to be combined. In a third step, the spatial data sets were overlaid and a rule-based method was used to identify the resulting surfaces as organic soil or not organic soil. In the final step, reliable information on the occurrence of mineral soils was used to delete surfaces for which the evidence of organic soil was considered less reliable. The total area of organic soils (including the ‘certain' and ‘less certain' estimates) is 32,702 ha. For many applications, this is the best estimate of the current occurrence of organic soils. The category ‘only documented in historical sources' refers to areas for which no current relevant information was found – neither in relation to mineral nor organic soils. The category ‘ambiguously documented' covers areas for which the evidence of organic soils is unclear; it is shown here solely for reasons of consistency with the previous surface estimate from 2015. <br> Due to the heterogeneous nature of the information sources used to create the map, it is not possible to define the scale for which this map is suitable. However, the following recommendation can be made: The map is suitable for use at national and regional levels (e.g. canton or district); it is not suitable for use at parcel level. <br> Two publications describe the methods and updated data sets in detail. It is recommended to read both publications before using the map.

Agricultural parcels with potential importance to amphibians, surfaces

Switzerland-wide map of agricultural parcels that are potentially suitable as either terrestrial habitat or as part of a dispersal route between amphibian breeding sites for up to 11 amphibian species. For each agricultural parcel, the dataset contains in its attributes information on which species (if any) are found in an amphibian breeding site near the parcel (within 200 m, 500 m or 1 km) and are likely to use the parcel as terrestrial habitat. Likewise, it is indicated which species (if any) are highly likely to have dispersal routes between breeding sites that pass through the plot.In the default view of the map, all parcels are shown that are suitable as terrestrial habitat for at least one species with a nearby spawning site (within 500 m) and/or along a dispersal route of at least one species. By selecting a parcel, you can see which species could potentially use that parcel using the columns “species_suitXXX” and “species_corridors" (Alias: "Terrestrial habitat XXXm" and "Dispersal"), which contain a list of the Latin names of each species. 'species_suit200' is suitable habitat for a species with a breeding site within 200 m, 'species_suit500' for 500 m and 'species_suit1000' for 1000 m. The map is based on the spatial combination of the Swiss Agricultural Parcel Map of 2021 (KGK-CGC. (2022). Agricultural Landuse 2021. https://geodienste.ch/) and suitability and dispersal maps for 11 amphibian species. The map differentiates between the basic agricultural parcels and overlapping elements such as biodiversity promotion areas and small structures. Only the data set with the basic parcels is available in the Federal Geodata Infrastructure. Further details can be found in the attached data description.

SilvaProtect-CH (hazard information at national level): Rockfall

Rockfall and large rock avalanches are characterised by the isolated falling movement (falling, jumping, rolling) of individual rocks or boulders of up to several cubic metres in size. They can reach speeds of up to 30 m/s. The moving rocks and boulders generally come to a halt on gradients smaller than 30°. Forests can reduce the kinetic energy of the boulders significantly. This layer contains a general hazard index map of potential rockfall and large rock avalanche trajectories based on the modelling of the rockfall and large rock avalanche process carried out by the SilvaProtect-CH project. The modelling of rockfall processes does not take the effect of forests into account.

National maps of Switzerland (grey)

swisstopo produces national maps in the scales 1:10'000 up to 1:1 Million. The layer National maps (grey) combines the different maps and shows the best fitted map for each zoom level. The layer National maps (grey) is used as base map in the swiss federal geoportal. It is also available as WMS and WMTS geoservices. Once a year, a copy of the WMTS tile pyramid is made available for download in JPEG format and in the Web Mercator coordinate system (EPSG:3857) up to zoom level/tile matrix 18 (0.5 m resolution).
Ecomorphology Level F

To enable surface waters to be fully protected, their status must be known. The Modular Stepwise Procedure provides the framework for standardized investigation and assessment of surface waters. The procedure is modular in structure and comprises surveys of hydrology, watercourse structure (ecomorphology), water chemistry and ecotoxicology, and the communities of animals, plants and microorganisms (biology).The Ecomorphology module surveys the structural characteristics of the streams and rivers in regions as a whole, e.g. cantons, regions, municipalities) (Level F).
Service to the population - accessibility

Measuring the distance to services for each inhabited hectare in Switzerland provides a wide range of statistical information on access to goods, services and recreation areas.Sufficient access to basic goods and services needed in everyday life, as well as access to places of retreat such as lakeshores or forests, are of great importance for the quality of life. The calculation of accessibility to these services is a method to measure this phenomenon. Accessibility is operationalised by the distance travelled on the road network between the place of residence and the location of the nearest service provider or the nearest recreation area. The places of residence are not considered individually, but are aggregated by inhabited hectares.
Federal register of Buildings and Dwellings: energy/heat source heating

The Federal Register of Buildings and Dwellings (RBD) was created on the basis of information from the 2000 population census for statistical purposes.
The RBD has established itself as the standard national information system for buildings, not least thanks to the total revision of his ordinance, which came into force on July 1, 2017.
The RBD contains information on construction projects, buildings, dwellings, entrances, and streets.
Level A data are public and can be used without restriction.
The data layer "RBD: energy/heat source of the heating system" shows graphically (color) the energy/heat source of the most powerful heating system and the relative update date (shape).
National maps of Switzerland (color)

swisstopo produces national maps in the scales 1:10'000 up to 1:1 Million. The layer National maps (color) combines the different maps and shows the best fitted map for each zoom level. The layer National maps (color) is used as base map in the swiss federal geoportal. It is also available as WMS and WMTS geoservices. Once a year, a copy of the WMTS tile pyramid is made available for download in JPEG format and in the Web Mercator coordinate system (EPSG:3857) up to zoom level/tile matrix 18 (0.5 m resolution).
Current drought situation in Switzerland

The map shows the combined drought index for each region. This index summarises in one value the various factors affecting drought: precipitation, modelled soil moisture and discharge (watercourses) or water level (lakes). The index is calculated by determining the extent to which the variables deviate from the statistically expected values for the measurement period 1991–2020 (known as the ‘reference or standard period'). It primarily shows how often an event occurs and can assign a value from 1 to 5. The higher the value the more unusual or extreme is the water deficit for the season.
Viticulture on slopes

In order to take the difficult production and living conditions in agriculture into adequate consideration, slope subsidies have been established for areas eligible for direct payments. A slopes dataset has been created for general direct payments (GeoIV 152.1; DSO Art. 43) and a dataset for vineyards on slopes for viticulture payments (GeoIV 152.2; DSO Art. 45). There are different categories of slope gradient. The vineyards on slopes dataset is part of the data used to calculate the agricultural direct payments on the basis of a geographic information system (GIS). Standardised calculations have been produced for the whole of Switzerland. The production is based on the "SwissAlti3D" terrain model from swisstopo. A distinction is made between the following slope gradient categories: &lt;30; 30-50; &gt;50 percent. Sloping areas less than 100 square metres in size were not taken into consideration.
Regional geothermal potential studies in Switzerland and Principality of Liechtenstein

This map shows the existing geothermal potential studies in Switzerland (per Canton) and Liechtenstein. The data basis that allowed the realization of this map comes from the report «Geothermie für die Nah- und Fernwärmeversorgung – Überblick über die kantonalen und nationalen Geothermie-Potenzialstudien, Nutzungsmöglichkeiten und Anwendungsbeispiele» from K. Link and O. Zingg and appointed by SwissEnergy. This report is available under the following link: <a href="https://geothermie-schweiz.ch/geothermie-fuer-die-nah-und-fernwaermeversorgung" target="_blank">https://geothermie-schweiz.ch</a>. Data was controlled and updated in order to ensure the highest possible accuracy of the displayed information.
