The JRC manages the control activities for the Common Agricultural Policy, including the acquisition of satellite images, on behalf of the Directorate-General for Agriculture and Rural Development. The images are distributed to contractors in the EU member states for processing and analysis, and are sent back to the JRC for archiving and proof of purchase. The CwRS activity is now one of the largest civil applications of remote sensing in Europe.
The JRC faced a significant logistical overhead in handling large volumes of raw imagery and particularly their redistribution to contractors, each of whom must generate accurate orthoimagery from raw scenes and locally sourced reference materials. Also posing significant challenges were demonstrating the fulfilment of data licensing requirements and in ensuring the consistency of orthoimages generated by contractors within the scope of the contract.
In order to address these issues, an image portal concept was conceived based on an already existing prototype of the ImageServer used internally at the JRC. The new solution will add functionality to the existing ImageServer in terms of:
- a fine-grained authentication system, allowing the ImageServer to function as an external image portal
- an automatic system for orthorectification of raw satellite images, using high-resolution reference imagery, and
- an OGC-compliant catalogue system for identification and access of satellite images.
The solutions will support all types of satellite sensors used in the CwRS program.
