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?

Possible areas of LSI Portal enhancements?


Presentation by Paul Davis, University of Maryland





Future Editions under discussion to provide access to LSIC:



Coordinated Sample Data Collections



Attribute search function, via postgreSQL database



Plan prototype interface attachment for map searching



Access open archives for ‘virtual’ searching

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
