ACCESS TO DATA FOR SERVICE SUPPORT Objectives ACCESS TO DATA FOR SERVICE SUPPORT The objective is to expand the access to data, information and images (from all archives) as chainable web services. A web service access to data, information and image for Service Providers through SSE Portal data ideally archived in every repository Access to data is already implemented for Landsat repository (Landsat) EOA (SPOT) MODIS MSG
EVOLUTION IN ACCESS TO DATA FOR SERVICE SUPPORT Objectives EVOLUTION IN ACCESS TO DATA FOR SERVICE SUPPORT ”Experiment Excellence” motto oriented to the user interaction New components/functionalities available to SPs Data tailoring Enforce Data Policy with a look to the future Focus on 3rd Party Missions BETTER USER EXPERIENCE SMARTER USE OF RESOURCES SMOOTHER SERVICE INTEGRATION
EVOLUTION IN ACCESS TO DATA FOR SERVICE SUPPORT Enhancements EVOLUTION IN ACCESS TO DATA FOR SERVICE SUPPORT Integration between WebMap Viewer interaction and Service Stylesheet. Pre-processing calculation of output data User perception of the amount of data Limiting resource usage through flexible data tailoring Data tailored in 3 axis: Space (AOI) Time Channel
EVOLUTION IN ACCESS TO DATA FOR SERVICE SUPPORT Enhancements EVOLUTION IN ACCESS TO DATA FOR SERVICE SUPPORT Enforcing the data policy 3 hour delay relatively to current time Data conversion to standard (and more useful) formats HRIT Compressed -> HDF Ready-to-use product Matlab IDL Service chaining
Enhancements MSG Product selection and Download Catalogue for selection and download of MSG products. Restricted to authorised ESA Cat-1 users The selection of products requires spatial and temporal coverage definition channel (bands) picking For each order process, it is possible to download a set of contiguous MSG timeslots for each of the specified channels. Data is available from January 2008 onwards

Data Access to SPs through Service Chaining Effort for the SP moves to BPEL Workflow chaining instead of Data Access
How collaboration changes everything - MSFRD Example Service Chaining How collaboration changes everything - MSFRD Example Service for analysis and comparison of Fire Detection algorithms. ESA (MDIFRM) CRPSM (SFIDE) User Standardization for collaboration Definition of an architecture to support heterogeneous data Collaborate on common representation of Hot Spots Definition of interfaces - Generalized XML Fire Detection (GXFID) Streamline integration
Service Providers can create value-added services Service Chaining Service Providers can create value-added services while respecting contextual boundaries if they share common interfaces.
The Future Provide data access to more Catalogues and Archives METOP AMSU-A MHS GRAS Improved delivery mechanism (HTTP vs FTP) (Proxy?) Create unique Data Access Service (TBD)
The End Thank you! Questions
