Status A prototype LSI Constellation Portal for Mid-Resolution
Optical LSI Satellite System Information and Enhanced Data Access was developed in cooperation with CEOS WGISS, and demo’ed at GEO V in Bucharest.
LSI Constellation Portal now operational

From presentation by Dr. Bryan Bailey to CEOS SIT, March 2009. The 2009 LSI Constellation Work Plan focuses on completing and
sustaining current and ongoing activities. LSI Constellation Portal for Mid-Resolution Optical LSI Satellite
System Information and Enhanced Data Access will be released by March 31.
In cooperation with WGISS, the LSI Portal will be enhanced to include other LSI satellite system data, as well as increased functionality.
Definition of standards for future mid-resolution, optical satellite systems is scheduled for completion in September.
The WGR likely will focus on facilitating application of CEOS agency radar data to the GEO task on Forest Carbon Tracking and on promotion of operational polarimetric SAR systems.
INPE will complete development of the web-based services or freeware.
The WGRDSC will continue to compile regional data sets and plan for its contributions to GLS2010.

From the LSI Constellation 2009 Work Plan INPE will prepare and circulate plans for development of
format conversion and orthorectified image generation capabilities.
The plans will identify the types of information they require from the contributing agencies, and the LSI Constellation Co-Chairs with be responsible for requesting the agencies to provide the needed information.
How might WGISS be of help? Presentation by Julio Dalge INPE LSI Constellation Ideas and Plans

LSI Portal Next Steps? Work with LSI Constellation Study Team via Dr. Bailey to
identify and prioritize portal enhancements Possibly pursue some prototype/demonstration
enhancements with two or more LSI Constellation members Demonstrate cross-system, granule level, search and retrieval
Additional attributes Browse imagery Geographic query
Possibly employ some standard or non-standard web service interfaces to agency servers
Would need to identify agency information system points of contact and bring them into the portal project team to
participate in defining best, standards-based approach. Identify possible reuse of an existing query user interface

Recommendations to WGISS? Contact LSI Constellation Study Team to specifically identify
next phase enhancements and prepare specific project plan for presentation at next WGISS
Specific support to INPE efforts?
Security Comments? Simple clearinghouse application presently thus simple
security measures However, if we expand to cross-system, granule level
queries, security complexity will increase significantly
