Belgium Flanders GSAA

Short Description

Flemish Geo-spatial Aid Application (GSAA) data is managed by the Belgium Department of Agriculture and Fisheries. It contains the parcels that are in agricultural use on the deadline for submission of the single application that year. The register also includes pounds, wood edges and agricultural production facilities (stables and similar buildings). The inventory of these parcels takes place annually in the context of the payment of the (co-financed) European agricultural subsidies and the Flemish manure legislation. It can be used for consultation or study of the land use of agricultural parcels for the year in question. This dataset does not contain all data from original GSAA dataset. Only the main crop and the production method are included as attribute information. It forms the basis for the aforementioned registration. The GSAA is prepared with screen digitization of the agricultural parcels of each farmer individually, based on the agricultural parcels of the previous year and the farmer's collective application. For the background, the most recent colour orthophotos of the Flemish Geographical Information Agency (AGIV) at that time are used.
