Derivative and complementary data

Besides the results of the Swiss land use statistics, the FSO offers some additional data which are produced from the mentioned land use statistics results or designed as complementary geodata to enrich the information on the subject of utilisation, cover und suitability of the soil surface available in Switzerland.

In addition to statistical information about land use and cover, cartographic representations also meet a common requirement. A cartographic representation of the sample points of the Swiss land use statistics often leads to an inhomogeneous, noisy and rather implausible map image. To obtain a more suitable basis for cartographic work, the FSO, in a process involving several stages, has condensed the point data of the land use statistics into 18 groups and generalised them geometrically. This data distributed under the designation of «simplified land use» is particularly suitable as map background in geographical information systems and applications.

With a project to establish a basis of know-how and experience in digital remote sensing and the utilisation of satellite data for statistical purposes and to complement the land use statistics by reliable information on the spatial distribution of deciduous and coniferous forest, the entire territory of Switzerland was classified to discriminate pure coniferous forest, mixed coniferous forest, mixed broadleave forest, and pure broadleave forest.

In the early 1990s, the four sheets of the land suitability map of Switzerland on a scale of 1:200,000 published in 1980 by several federal offices were digitalised. Subsequently, the FSO combined them into a consistent data set, improved and corrected the geometry and topology and finally integrated the new geodata product in its GEOSTAT range of data.
