Earth Observation Data Processing in Distributed Systems

Earth observation systems have a continuous growth in the user and internal requirements that can be handled nowadays only using distributed systems. These requirements are shortly reviewed in this paper. Huge data-sets management and processing are of special interest, as well as the particularities of the Earth observation data. On the technological side, the focus is put on service-oriented architectures that are facilitating the linkage of data or resources and processing. As proof of concept of current distributed system capabilities, the technological solutions used to build a training platform for Earth observation data processing are exposed and discussed in details.
