3. 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

4. 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

5. 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

6. 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

7. 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

13. Service Development Output Product From HRIT to HDF Clipped to the AOI
Geolocated
Contiguous set of time slots

14. Data Access to SPs through Service Chaining
Effort for the SP moves to BPEL Workflow chaining instead of Data Access

15. 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

16. 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.

17. 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)

18. The End
Thank you!
