The GSAA, provides the annual spatial declaration of the farmer in the frame of the Common Agricultural Policy. Data can only be shared anonymized; it does not contain personal information that could be used for the identification of the farmer. The polygons of the dataset locate agriculture land that is managed by the farmers. A parcel can only be associated to one farmer and can contain one or multiple land cover/use polygons such as; Arable Land, Fruit, Vines, Olive Trees, Artificial Sealed surfaces, Landscape Features, Green Houses, potential arable land that is not maintained is a state suitable for cultivation. In cases where the farmer applied for a specific scheme or has certain obligations like greening, this layer would also include the crop type. Information on crop type is thus not comprehensive.
