LSI Portal Enhancement Proposal

Status of the LSI Portal





The prototype LSI Constellation Portal was demo’d at the
CEOS Plenary in 2008 and at GEO V in Bucharest.
The LSI Constellation Portal became operational in March,
2009
This past fall added a links to Forest Carbon data the GEO
FCT sites
The GEO and others have reviewed the LSI Portal and
offered a number of suggestions for enhancement
The most significant and challenging recommendation is to
add a map-based query capability to the Portal to allow
users to identify available satellite data over specific
geographic areas of interest.

LSI Portal Enhancement Proposal

The current LSI Portal is essentially functioning as a
directory of the mid-resolution optical data holdings
of the various member agencies.



It provides instrument and mission characteristics and direct
links to the agency systems where specific data granules
can be queried, ordered and accessed.
To be meaningful and effective, incorporating a mapbased query capability would need to be at the
granule or individual satellite acquisition level.
WGISS technical members refer to this as an
inventory-level query capability.

LSI Portal Enhancement Proposal


From an LSI Portal perspective, the recommendation
to add a map-based query capability would translate
into a recommendation to . . .
Expand the functionality to include cross-system,
granule-level, search and data retrieval

Description: Expand the functionality to go beyond directory
and metadata about sensors and platforms to being able to
initiate a granule-level search across multiple LSI member
systems to select and obtain individual data granules
directly through a single portal without having to be linked or
handed off to other member portals or web sites.

WGISS has been exploring cross-agency, satellite
data systems query and data access mechanisms.
Desiring to follow the services-oriented architecture of
GEOSS and employ standards wherever possible.
At WGISS #29 in Pretoria, plans formulated to initiate
a project called the CEOS WGISS Integrated Catalog
(CWIC).

CWIC Capabilities





CWIC will provide an access point for major CEOS agency
catalog systems.
CWIC will interface to user interface clients by using the
GEO standards.
CWIC will send directory/collection searches to the
International Directory Network.
CWIC will distribute inventory/product searches to the
CEOS agency inventory systems using the agency systems
native protocol.
CWIC will be offered as the CEOS community catalog as
part of the GEO common infrastructure.

CWIC (cont.)




NOAA is providing the initial funding for the CWIC prototype
by providing engineers to participate in the CWIC design
team and implementers to implement the major CWIC
components.
Other participating CEOS agencies are expected to
contribute at least one engineer each to the CWIC design
team and to implement the actual access to their own
agency inventory system.
The end result of the design team activities will be a
distributed search and access to satellite inventory data at
the CEOS agency data systems.
Current list of participating agencies: NOAA, USGS, NASA,
JAXA, ESA? JRC?

Proposal to LSI Constellation Study Team:





LSI Portal participation in the CWIC Prototype
Demonstrate a map-based and temporal queries via the LSI
Portal to several LSI member agency systems/data sets
For example, initiate a map-based and temporal query of
Landsat scenes on the USGS inventory server and return
results to the LSI Portal to then initiate download of selected
scenes.
