Land use statistics based on the standard nomenclature NOAS04

Land use data in 72 basic categories, aggregated into 27 or 17 classes and 4 main categories, obtained by visual interpretation of sample points from a regular 100-metre grid on three-dimensional, digital aerial photographs. Land use and land cover are surveyed separately since 1979, making two items of information available for each sample point, which could be evaluated individually (as "pure" use and coverage) and in almost any combination. The standard nomenclature (NOAS04) according to 17 classes is shown here visually.
