11. Systematic SAR Data Processing
● Systematic processing using the InSAR Browse of DLR.
Each tile has the extent of an S-1 footprint.
● Providing amplitude (cyan) and
coherence (red) of all consecutive
S-1 pairs over the world tectonic mask.
● Current production rate: 150 pairs/day
● About 1TB data cached and processed daily
● Published results available freely to any user
Systematic production of S-1 InSAR pairs

12. Systematic Optical Data Processing
Surface Temperature Map developed and integrated by INGV,
processes systematically Landsat-8 data
to measure the temperature for areas
identified as «thermally active» in the
volcanic areas (22 volcanoes worldwide)

14. Monitoring Systematic Productions
Monthly consumption of 7K CPU/hours for processing generating more
than 15K products per month (even before entering in pre-operations)
Full-fledged dashboard with custom metrics to monitor processing

15. Monitoring Systematic Productions
Routine monitoring for processing data access
Data Gateway Access in 2018
before starting the pre-operations phase

16. GEP and EPOS
A long-term plan to facilitate integrated
use of data, data products, and facilities
from distributed research infrastructures
for solid Earth science in Europe
● GEP is providing EO data processing expertise in exchange for
access to the EPOS in-situ data network
● GEP will be available to EPOS IP users and provide the interface
for the Satellite Data Thematic Core Services towards the EPOS
central hub.
EPOS - European Plate Observing System

17. The GEP and international initiatives
● Taking lessons from the GEP experience, a broader approach
developed jointly with space agencies ESA, CNES, DLR and ASI
○ aims to address priorities of the Sendai Framework for Disaster Risk Reduction 2015-
2030 taking advantage of satellite EO
○ goal: provide an EO processing & e-collaboration environment to exploit EO data to
assess geohazards and their impact
○ elaborated in the framework of CEOS WG Disasters and accepted by CEOS
○ a resource to support CEOS WG Disasters Pilots (e.g. Seismic Hazards, Landslides,
Volcanoes, Recovery Observatory) and GEO DARMA
● The GEP is also selected by the CEOS WGISS alongside the Data
Cube framework
Geohazards Lab Initiative

18. GEP & Disaster Risk Management Services
● International Charter Space and Major Disasters
selected a GEP Thematic Application for testing the
support to the Project Manager and Value Adding
partners of Charter activations:
○ Faster access to data and ancillary datasets (e.g. DEM, OSV, etc.)
○ On-line pre-processing of images (co-registering multi-sensor collections),
○ On-line image analysis (e.g. change detection, a classifier to generalize some
processing)
● ESA initiated a special contract to develop the GEP based prototype
to evaluate Exploitation Platform potential contribution to disaster
response
Charter Platform prototype

19. Ongoing Activities
● Thematic Apps: rule-based bundling of data collections and
processing services
○ Targeting specific usage scenarios
○ Processing services accessed on the GEP Portal via “Discover Thematic Apps”
○ My data uploads App: for user uploads on Data Gateway, with automated cataloguing
● Terradue Data Agency
○ Automatic multi-sourcing
○ Programmed cache
○ Personal storage (repository)
○ Production staging
○ Data usage accounting
New exploitation platform capabilities agreed upon with ESA

21. Open Cloud Strategy
■ Open APIs
Embrace Cloud bursting APIs that can
be easily plugged into the Platform’s
codebase, so to expand the Platform
offering with Providers offering
complementary strategic advantages for
different user communities.
■ Developers community
Support and nurture Cloud communities
that collaborate on evolving open
source technologies, including at the
level of the Platform engineering team,
when it comes to deliver modular
extensions.
Roadmap for interoperability
■ Self-service provisioning &
management of resources
The Platform’s end-users are able to self-
provision their required ICT resources
and to work autonomously.
■ Users rights to move data
as needed
By supporting distributed instances of
its EO Data management layer, the
Platform delivers the required level of
data locality to ensure high performance
processing with optimized costs.

22. Earth Observation Exploitation Platform
● This Domain Working Group charter defines the role for OGC
activities within the Earth Observation Data Exploitation platform
domain
● Provide an open forum for the discussion
● Presentation of interoperability requirements, use cases, pilots,
and implementations of OGC standards in this domain
● Promote OGC standards
It will not define a new platform or a new architecture
