G4CAP 2.0

Dear G4CAP users,

   today the system is going to be upgraded to version 2.0, providing new important features for MSs Administrations, so it will be unavailable for about half a day. We thank you in advance for your understanding and patience.


Dear G4CAP users,

  we are glad to announce that the S2 Alert module is now working well and this morning we successfully completed the latest Sentinel Requests to be managed over Ireland. Actually we have solved the issue with ESA infrastructure since the 19th of August, but we waited for completely manage all the Sentinel Requests in the system before making this announce.

Please exploit this feature as much as you can, in order to evaluate the usefulness of Sentinel-2 imagery for your controls and provide important feedbacks for 2017 Campaign.

In case of issues or requests for information, do not hesitate to contact us at, or check the manual available in the Documentation section.


Dear G4CAP users,

   after two very positive months of tests of the Sentinel2-alert module (more than one hundred Sentinel Requests collected, hundreds of compliant S2 Acquisitions stored and notified), we are now facing some technical issues in the interaction with the upgraded ESA S2 infrastructure.

We are in strict contact with ESA support team to figure out what is causing the issue (that seems to be on their side) and how to solve the problem. Unluckily we have to suspend our service until a solution is found. We will come back to you as soon as we will have (good) news and data search will be reactivated. Thanks a lot for understanding.

G4CAP upgraded to version 1.6

Dear G4CAP users, upgrade to version 1.6, housing the new modules for Sentinel-2 alerts, and other updates visible in the versions log have been done. We will soon issue an instruction for the S2 alert sw module.

Welcome to G4CAP, Web application for the management of the CwRS campaign. 

This application, provided by the Joint Research Centre for DG AGRI, allows Member States Administrations and their Contractors to check for satellite images acquired over their Countries to perform controls over CAP declarations.

The CAP is a common policy for all the Member states of the European Union. It is managed and funded at European level from the resources of the EU annual budget.
