Federal Inventory of Raised and Transition Bogs of National Importance
Raised bogs are some of the most susceptible habitats in Switzerland and are in sharp decline. Today, between 10% and 20% of the original stocks still exist. The scientific inventory of r...
Federal Inventory of Landscapes and Natural Monuments
Article 5 of the Federal Act of 1 July 1966 on the Protection of Nature and Cultural Heritage (NCHA) orders the Federal Council to compile inventories of sites of national importance (fed...
Federal Inventory of Mire Landscapes of Particular Beauty and National Significance
Mire landscapes are essentially semi-natural landscapes shaped by mires that are also home to other noteworthy natural and cultural elements. They are the last remaining habitats for vari...
Federal Inventory of Dry Grasslands of National Importance - Addendum 2
Dry grasslands are habitats with a wide variety of species that are marked by agricultural use. In accordance with the Federal Act on Protecting Nature and Cultural Heritage, the most imp...
Federal Inventory of Dry Grasslands of National Importance (DGS)
Dry grasslands are habitats with a wide variety of species that are marked by agricultural use. In accordance with the Federal Act on Protecting Nature and Cultural Heritage, the most imp...
Federal Inventory of Reserves for Waterbirds and Migratory Birds of international and national importance
Switzerland is especially important as a wintering and resting site for various migratory waterbirds. As a result, in 1974 the Federal Council signed a convention on watercourses and wetl...
CO2 emissions from thermal fuels (corrected for weather conditions) and motor fuels
Evolution of CO2 emissions from thermal and motor fuels. The CO2 emissions from thermal fuels are corrected for weather conditions (the correction for weather conditions takes into accoun...
Database of total bedload (federal government)
A bedload transport database for surface waters throughout Switzerland. Following the devastating events of the summer of 1987, which caused major damage in many regions of Switzerland, t...
Reaches surveyed - cross section securing point
The map shows the reaches of watercourses which are currently surveyed periodically under the leadership of the FOEN. They are usually surveyed every 10 years or after major floods which ...
Database of cross sections (CS) - surveyed sections
The map shows the reaches of watercourses which are currently surveyed periodically under the leadership of the FOEN. They are usually surveyed every 10 years or after major floods which ...
Diffuse dissolved phosphorus inputs into waters, modelled values
Phosphorus inputs into waters represent an undesirable pollution load. Over recent decades high inputs of dissolved phosphorus have led to eutrophication of the lakes of the central plate...
Diffuse total phosphorus inputs into waters
Phosphorus inputs into waters represent an undesirable pollution load. A total of some 3,400 tonnes of total phosphorus (dissolved and particulate phosphorus) enter Swiss waters every yea...
Diffuse total nitrogen inputs into waters, modelled values
Nitrogen inputs into waters represent an undesirable pollution load. Under the Convention for the Protection of the Marine Environment of the North-East Atlantic (OSPAR), Switzerland agre...
Catchments in karst regions
The Karst catchments layer depicts those areas where seepage water flows into a specific spring and feeds it. Catchments can occasionally overlap, namely where sections of them drain towa...
Catchment units in karst regions
The Karst catchment units layer consists of the unit areas from which similar groundwater flow behaviour towards the karst spring can be expected. In particular, it allows for the phenome...
Seismic zones according to the SIA 261 standard
Map of seismic zones from the SIA 261 Standard “Actions on Structures” (2020). A design value is specified for the horizontal ground acceleration agd (in m/s2). This design value is requi...
Determination and modelling of the upper timberline for the standard periods 1961–1990 and 1981–2010, and the future period 2070–2099
This map shows the natural upper timberline (excluding anthropogenic influences and without considering shrub forest) modelled for the periods 1961–1990, 1981–2010 and 2070–2099. The foll...
Extreme Point Precipitation
The maps on extreme point precipitation describe the precipitation depths for rare heavy precipitation events under current climatic conditions. The analyses can be presented for return p...
Fine particulate-matter concentration along the A2 and A13
The survey on air quality along transit routes through Switzerland assesses traffic-related air pollutants that are relevant to health. These pollutants typically arise from combustion an...
Air pollution by particulate matter PM10
"Particulate matter" (PM10) refers to particles less than 10 micrometres in diameter. These particles are formed during industrial and commercial production processes, combustion processe...
River basins (catchment areas)
The river basins form the uppermost aggregation level for the "Topographical catchment areas of Swiss waterbodies" geodata set. The large areas with a surface area of usually more than 10...
Strahler stream order
The stream order according to Strahler specifies the degree of branching of a hydrographic network. It forms the basis for morphological studies and descriptions of a watercourse. --- Acc...
Frequency of Föhn in the year, period variable (maximum 1969-2013)
The map shows the average frequency (in %) of the number of Föhn hours per year. A value of e.g. 12 % means that on 44 days in the year the Föhn blows, whereby the duration of the Föhn ev...
