SDK concept

The Copernicus/GMES Space Component consists of the five foreseen Sentinel Earth Observation (EO) missions. The first mission, Sentinel 1, was launched on a Soyuz rocket from Europe’s Spaceport in French Guiana on 3 April 2014 and it has the goal of provide C-Band SAR data. The other two initial missions, Sentinel 2 and 3, will also be devoted to the Earth surface characterization (land and ocean), and are currently planned for launch starting in mid 2015. The two missions devoted to atmosphere sounding, Sentinels 4 and 5 will be launched several years later, from 2019 onwards, and will generate huge amounts of data that are not easily integrated into processing chains outside the space agencies ground segments. Very often, public and private institutions do not possess the computing power and storage capacity to profit from the amount of data required to implement, test and deliver end-user services based on Earth Observation data.

SenSyF Framework

During 2014, it was designed and developed an acquisition and processing framework which allows any potential user easy access to all Sentinel datasets, and in which the user can build its own novel Service for exploitation of Synergetic Sentinel data. It has also been developed a Service Development Kit (SDK) containing a complete set of data access, data processing and data dissemination tools which have the purpose of satisfy and simplify the deployment of the service’s workflows. This SenSyF Service Development Kit is built upon the processing infrastructure and is delivered as part of the SenSyF Sandbox environment. To learn more about the content of the SDK click here.

The SenSyF Framework establishes a system for automated data acquisition and processing, including a specialized Sandbox Service with tools and development platforms where Service developers are able to implement and test their applications, and then tap into a distributed pool of Cloud resources when ready for the exploitation phase.
It is important to note the existence of two different environments, Sandbox and Operational Cloud. The main idea is once an application processor is fully integrated and successfully tested, on the Sandbox environment, it is ready-made to process large volumes of datasets on clusters of any size (Operational Cloud). The parallel processing framework enables compute intensive capabilities during an exploitation phase, with high level of configurability. The framework will also allow making queries directly to the Sentinel Catalogue (ngEO – Next Generation Observation system).
Thus, the SenSyF Framework system will be able to solve the Services’ problem of handling with large volume of Earth Observation data and ingest it into computationally demanding processing chains. Thanks to a scalable parallelization system and considering the capacity for managing a hybrid Cloud infrastructure, SenSyF can support new business models aiming at “Hosted services”, operating at a large scale, and potentially covering the full life-cycle of a wide range of Sentinel applications. The figure below explains the technical system of the SenSyF framework.
