which after trade-off with the system available capacity are propagated in the <strong>GSC</strong> DAP,<br />
where GMES Services updated requirements and evolving space systems capacity are<br />
taken into account. The DAP Data Sets are pre-defined collections of coherent multimission<br />
products responding to specific different users needs and therefore with different<br />
characteristics.<br />
The CDS interfaces with the GMES Service Component for gathering data requests and<br />
providing coordinated data access and services, and with the Ground Segments of the<br />
GCM’s and the <strong>Sentinel</strong> missions for coordinating the data provision from the GCM’s in<br />
response to the requests.<br />
Figure 1-1 sketches the <strong>GSC</strong> Data Access System context, the role of the Coordinated<br />
Data Access System (CDS) and its interface with the GMES Service Segment (for gathering<br />
data requests and providing coordinated data access and services), and with the Ground<br />
Segment of the GCM’s and the <strong>Sentinel</strong> missions (for coordinating the data provision in<br />
response to the requests). The <strong>GSC</strong>DA data and services provision from the GMES<br />
Contributing Missions (GCMs) is regulated through specific agreements with <strong>ESA</strong> through<br />
the DAP Management function. Being dedicated GMES missions, the latter interface is not<br />
strictly necessary for the <strong>Sentinel</strong> missions.<br />
