GEOSS AIP-4 CFP Response
NOAA-NASA GOES-R and GMU CSISS Joint Response to the GEOSS
AIP-4 CFP
1 Overview
One purpose of this joint response from NOAA-NASA GOES-R ground segment and
GMU CSISS is to offer Geostationary Operational Environmental Satellites (GOES)
images and derived products as part of GEOSS Data-CORE, to make them persistently
discoverable and accessible through the standard OGC Catalog Service and OGC Web
Coverage Service interfaces, and to fully align these services with the GEOSS Common
Infrastructure. Another purpose is to contribute the CEOS WGISS Integrated Catalog
(CWIC) as a mediated access enabler to the CEOS members’ satellite data catalog.
The contents of this response include specific proposed contributions to the two AIP-4
activities: Access to Priority EO Data Sources, and Clients and Mediated Access
Enablers. This NOAA-NASA GOES-R and GMU CSISS joint efforts will benefit the
GEOSS communities by making valuable GOES images and derived products freely
accessible online through standard web service interfaces.
2 Proposed Contributions
The team proposes to contribute to the two AIP-4 activities: Access to Priority EO Data
Sources, and Clients and Mediated Access Enablers.
2.1
Access to Priority EO Data Sources
2.1.1 Persistent OGC CSW and OGC WCS interfaces to the long-term
archive of GOES images and derived products at CLASS
The team proposes to enable the persistent discovery of and access to the long-term
archive of the GOES images and the derived products through standard OGC CSW and
WCS Web Service interfaces.
GOES images and derived products are currently archived at NOAA's Comprehensive
Large Array-data Stewardship System (CLASS), which provides data browse, order, and
download functionalities. Currently, no standard web service interfaces are provided in
CLASS. The GOES data collections in CLASS include: Aerosol Optical Thickness,
GOES Satellite Data - Block 11, GOES Satellite Data – Imager, GOES Satellite Data –
Sounder, GOES Satellite Data - VISSR/VAS (GOES-7 and earlier), Sea Surface
Temperature, and GOES Surface and Insolation Products(GSIP). GSIP contain
upwelling and downwelling shortwave (0.2-4.0 micrometers) and visible (0.4-0.7
micrometers) radiative fluxes at the top of the atmosphere and at the surface, cloud
fraction and skin temperature. In addition to these primary products, cloud phase, visible
cloud optical depth, outgoing longwave radiation, as well as derived byproducts
(composite clear and cloudy reflectances) and ancillary data (total column amounts of
water vapor and ozone) are also included.

GEOSS AIP-4 CFP Response
For the OGC CSW interface to NOAA GOES data in CLASS, the team has previously
experimented with two different approaches: one is utilizing the prototype Simple NOAA
Archive Access Protocol (SNAAP) API developed by Eric Kihn and Rob Prentice at
NOAA’s National Geophysical Data Center (NGDC), and the other is through a browser
simulation approach with the NOAA’s CLASS system directly. The second approach has
been verified as a workable solution in making GOES data discoverable through the
OGC Catalog Service for Web (CSW) 2.0.2, but the solution is not very robust since
when CLASS web pages are changed, we have to redo the browser simulator.
During the AIP-4, we will experiment with the new NOAA API package: NOAA
Enterprise Archive Access Tool (NEAAT). This package is very promising in providing
directly discovery of and access to the NOAA data, including GOES products. The team
will develop NEAAT-based OGC CSW service for a more robust solution for
discovering GOES product.
For the OGC WCS interface to NOAA GOES data, GMU GeoBrain WCS has been
demonstrated as a feasible solution during the GOESS AIP-3 and OGC OWS-7.
Coupling this OGC CSW interface and OGC WCS interface, the GOES products can be
persistently discovered and accessed through standard Web service interfaces.
2.1.2 Integration with the GOESS Common Infrastructure
This OGC WCS and OGC CSW will be registered with the GOESS Component and
Service Registry respectively. Each type of GOES images and each type of derived
products will also be registered with the GCI as data collection. These registrations will
be linked with developed thesaurus for EO observation parameters.
2.2
Activity #2: Clients and Mediated Access Enablers
2.2.1 Contributing CEOS WGISS Integrated Catalog (CWIC) as a mediated
access enabler
The CEOS WGISS team has discussed a preliminary design for the CEOS WGISS
Integrated Catalog (CWIC) with the following 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.
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.
As of 1 May 2011, the CWIC version 1 has established partnerships with the following
agencies: CEOS - IDN, NOAA CLASS, NASA ECHO, USGS Landsat Catalog System,

[http://geobrain.laits.gmu.edu/cwic/]. By early September 2011, the CWIC version 2
release will demonstrate the data access functionality. Therefore, the CWIC will enrich
the GEOSS AIP-4 by enabling a mediated access to the CEOS agency catalog systems to
bring the massive satellite data online.
2.2.2 Contributing GMU GeoBrain Online Analysis System (GeOnAS) as a
general Earth observation (EO) data discovery and analysis client
GeOnAS (http://geobrain.laits.gmu.edu/OnAS/) is designed for online analysis of EOS
and other online data. Based on service oriented architecture, the online analysis system
provides multisource geospatial data discovery, heterogeneous geospatial data retrieval,
simultaneous geospatial data visualization, and powerful geospatial data analysis
equipped by those large amounts of interoperable geospatial Web services. It allows users
to dynamically explore and preprocess any part of the petabytes of archived data and get
back customized information products rather than raw data. All this can be done with a
regular Internet connection to users’ desktop/laptop computers.
The team would like to contribute the GeOnAS system as a GEOSS component that
enables exploitation of Priority EO Data Sources.
2.2.3 Integration with the GOESS Common Infrastructure
The CWIC system will be registered with the GEOSS CSR as a Community Catalog
component. Each discoverable EO collection will also be registered with the CSR as a
data collection. The GeoBrain Online Analysis System will be registered with the CSR as
a general EO client. These registrations will be linked with developed thesaurus for EO
observation parameters.
