Nature Landscape Armed Forces (NLA), natural values/ habitats on land used for military purposes

The DDPS is one of the most important landowners in Switzerland. A large part of the areas used for military purposes are within the perimeter of nature and landscape protection inventories. The military usage favours the preservation of natural values in many places, for example, in amphibian spawning sites. However, it can also have adverse effects, which should be minimised. The interests of national defence and nature conservation are of equal importance in the Federal Constitution.For 20 years, the DDPS has been protecting and promoting the diversity of species and their habitats on the army sites with the programme Nature, Landscape and the Armed Forces (NLA). As part of this programme, the natural values as well as the utilisation by the Armed Forces and by third parties have been recorded on the larger sites such as military training areas, shooting ranges and aerodromes, the conflicts identified and measures to mitigate them defined and implemented. The respective files are updated periodically or in the case of major changes. The NLA data represents the mapped valuable natural values and habitats on areas used for military purposes. Valuable refers, on the one hand, to all habitats which have a protection status. Either the habitat is protected by the NCHA or the area is in a national, cantonal or communal inventory. In addition to these protected habitats, other habitats/ areas worthy of protection are also recorded, such as species-rich areas or areas where the main purpose is to promote biodiversity.

swissALTIRegio monodirectional Hillshade

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

swissALTIRegio multidirectional Hillshade

The hillshade is derived from the digital elevation model swissALTIRegio. It illustrates the surface relief of Switzerland, the Principality of Liechtenstein and the neighbouring regions. A hillshade is derived from the elevation model by calculating the exposure of the surface to sunlight at a certain or several angles. The swissALTIRegio hillshade uses a multidirectional method that combines light from 6 different sources (sun's positions). The average sun's position is located to the northwest.

Large-scale photovoltaic systems in Switzerland

Depending on their location and orientation, high-alpine photovoltaic systems can generate more electricity per installed kilowatt of power in the winter months than comparable systems in the lowlands. This is because the radiation conditions are better (thinner atmosphere, less fog) and because the sunlight is reflected by the snow (known as the albedo effect). This dataset contains all information on planned or realised large-scale photovoltaic installations that have been reported to the SFOE.

Cadastre of obstacle limitation surfaces

Obstacle limitation surfaces are a series of three-dimensional surfaces that delimit the obstacle-free airspace generally required for flight safety. Objects that penetrate these limitation surfaces are referred to as aeronautical obstacles. The aim is to protect the airspace from obstacles so that safe flight operations can be guaranteed. The obstacle limitation surfaces cadastre (OLS) is an official determination of the obstacle limitation surfaces for an airfield, an air traffic control facility or a flight path. The Federal Office of Civil Aviation (FOCA) maintains this cadastre for civil installations. This maps all types of three-dimensional obstacle limitation surfaces in accordance with ICAO Annex 14 in a structured and unambiguous manner.
