IIM - ESA Projects vs. Area

IIM - Probabilistic IM

KIM
The user trains the system providing positive /
negative examples
Training is linked to basic characteristics of
pixels / areas (e.g. radiance, texture, )
Learned knowledge is applied to all ingested
images
Thumbnails of images matching training are
returned in relevancy order
The training can be refined with further examples

IIM Available in 2004

KIM available for replication at SPs, experts,
facilities, ...
KIMV KIM implementation/validation for small
archives
Implement interfaces and operational features
Evaluators validating the system for selected
products
MIMS KIM implementation for MERIS L1RRP,
provides
Content Based Image Selection
To select images also via cloud coverage (lt
threshold over user area of interest)
Provided as SSE service (chainable with other
services)
Interactive Information Discovery
For user discovery of other features (fires,
algae blooms, )
For system training and creation of new SSE
services

SI - Characteristics

Easy service publication, chaining, activation,
provision
Services to remain at Service Providers sites
Support for on-line (RT NRT) and off-line
services
Permit Simple Catalogue Services, with parallel
access(key catalogue functions enveloped as
simple service, chainable with other services)
Allow services in national language
Maximise use of standards (W3C, OGC, )
Evolving with Service Providers requirements
Environment not binding and neutrally managed

14
SI - Implementation Plan

Multi Application Support Service System (MASS)
GSTP project B, I, N 3 years completed at end
of 2003
Output prototype with Portal, ToolBox, sample
services
Service Support Environment (SSE)
Available from end 2004, with about 20 services
Including Simple Catalogue Service (Envisat /
SPOT tested)
Neutrally managed / maintained by ESA (funds
available until 2007)
European Services Infrastructure (ESI)
SSE evolution (new req. automation, e-commerce,
OGC, GMES, TESI, INSPIRE, )
Start / end 2005 / 2007 funding GSTP

15
SI - SSE Implementation Contracts
16
SI - Available in 2004

Service Support Environment (SSE)
Easy Publishing, Chaining, Activation, Provision,
Monitoring
Hosting about 20 Services
Uses a Workflow engine and only two commands
RFQ, Order
Neutrally managed by ESA
ToolBox provided free-of-charge
System and ToolBox maintained by ESA on SPs
requirements
New Service Providers can join on request
benefits
Services NOT MOVED (full CONTROL/EXPLOITATION of
existing infrastructure)
Exploitation of SYNERGIES with partners (SPs,
developers, scientists, )
Reduction of COSTS and TIME TO MARKET

17
SI - Available in 2004 (cont.)

Simple Catalogue Service (via SSE)
Permits inter-accessibility of catalogues(paralle
l activation and recombination of results)
Access to key catalogue parameters as simple
service
Can be chained with other services
Two specific commands for performance Search,
Present
Relevant for single missions or constellations
(even distributed)
Maintained / enhanced by ESA within SSE
Successfully tested for Envisat / Spot with CNES,
Spot Image, EUSC
Other catalogues can be supported / activated on
request
