The management of the Common Agricultural Policy (CAP) grants generates a very high volume of data every year. The declarations include alphanumeric and geospatial information of farms, such as parcels, crops, hectares, irrigation systems and work units. Around 50 000 farmers make their declarations every year and these are submitted for administrative checks and about 5% are submitted for spot checks. Because of these controls (administrative and on-the-spot) the farmers’ declarations and the Land Parcel Identification System (LPIS) are always kept updated. There is no other system with such a short renewal cycle, so significant investment in updating cartography and all this updated and reliable data has a great value for other actors, beyond the manager of the grants.
The objective of the ‘Spatial IACS data supply of farms in Catalonia’ project is to help farmers improve their declarations. This makes them more reliable and accurate, preventing graphic overlaps between farmers and supplying open data for the agrarian sector, citizens and administrations. For this reason, three tools have been developed: the individual information of each holding (Cromos), the claim year declaration layer and the declared crops map.
