Land use statistics of Switzerland
The Swiss Land Use Statistics of the Federal Statistical Office collects information on land use and land cover in Switzerland every 12 years on the basis of aerial photographs from the Federal Office of Topography (swisstopo). In addition to statistics, the area statistics also provide geographic base data in hectare resolution for geographic information systems (GIS) of the federal government, the cantons, research institutes and universities. It also provides inputs for national programs such as Biodiversity Monitoring Switzerland and indicator systems.
The land-use statistics Art. 65, 73, 75, 77, 104 from the Federal Constitution , Art. 3 from the Federal Statistics Act , the Federal Council Resolution of February 17, 1982 and the Ordinance of June 30, 1993 on the implementation of statistical surveys of the Federal (SR 431.012.1), status 2004.
The area statistics are carried out in the form of a point sample survey on aerial photographs of the Federal Office of Topography . 4.1 million sample points are made in a grid of 100 m × 100 m.
The total area of Switzerland is recorded on the levels of Switzerland, cantons , districts , municipalities and hectares as well as any spatial units. The recording characteristics are divided into 72 categories for land use and land cover in the areas of settlement (building and industrial areas, traffic areas, recreational facilities, dismantling, landfill, construction sites), agriculture (arable land, meadows, pastures, fruit growing, viticulture and horticulture), planted areas ( Forest, shrubbery forest) and unproductive areas (bodies of water, unproductive vegetation, rock, sand, scree, glacier, firn).
The area statistics have been carried out every 12 years since 1979. The statistics are created in the year following the creation of the aerial photographs and are available no later than two years after the corresponding aerial photographs. The aerial photographs of the Federal Office of Topography are taken every six years (1979/85, 1992/97, 2004/09).
