Four Projects
• NASA WorldWind Java integration with GOS catalog for Search and Rescue clients
• CarbonTools desktop widget and gadget for GOS feeds and data services
• GMU/ESIP Geoscience portal access to the geodata.gov catalog
• GeoFinder for the Environment
Leveraging GOS Map and Data Services for Search and Rescue Operations using NASA WorldWind Open Source
3D Visualization Platform • Objective
– Enhancing the NASA Goddard Search and Rescue (SAR) Mission Office’s Decision Support Tools with access to data from GOS using NASA WorldWind-based application
• Technical Approach– Discover SAR relevant data via the GOS portal catalog– Access, exploit and visualize discovered data in WorldWind’s 3D
environment– Inform the SAR user of relevant resource updates from GOS
• Project duration– July 25 2009 – July 23 2010
• Team– Nadine Alameh, Project Manager– David Collins, WorldWind Software Engineer
Leveraging GOS Web Services• Finding the data: OGC Catalog Service for the Web (CSW)
– GOS is supported by a OGC Catalog Service for the Web (CSW) catalog that allows other external clients to search and retrieve metadata on data, services and other resource types referenced by URL
• Visualizing the data: OGC Web Map Service (WMS)– WorldWind supports OGC Web Map Service
• Outcome– Discover SAR relevant data via the GOS Portal Catalog– Access, exploit and visualize discovered data in 3D
environment– Inform SAR user of relevant resource updates from GOS– Enable Java WorldWind users access to the GOS Catalog
(and other OGC CSW catalogs)

Visualization of Data via WMS
Update Feeds
- All updates- Live Map Server updates- Most recent search updates
- All updates- Live Map Server updates- Most recent search updates
Benefits to SAR• Enhanced discovery, integration and visualization of data
– Tapping rich data services of the NSDI including data that SAR personnel may not have otherwise been able to locate or use in time
– Combine data (recent and historical) on-demand at various levels– Get latest data directly from its custodians hence alleviating the data
assembly overhead in SAR situations
Power of Web Services and Standards• Access to NSDI = access to needed data!
– Access to official sources of information – Quality information through FGDC Status Checker– Ease of integration into new markets and domains
• Catalog + 3D visualization + Open Source Java SDK = Powerful combination– Open source solution based on standards and web services = sustainability,
more users, easier integration within applications, wider reuse, etc. – Updated by community as GOS evolves and standards mature/change– Inherits all the advances made by WorldWind community (e.g. support for KML)
• Catalog CSW = opening new doors for discovery and connections– Little effort to connect to other catalogs (such as GEOSS, ESA FedEO, etc)– Staying up-to-date with recent updates feature

Utilizing GOS Map and Data Services for Cross-agency Earth Science and Geospatial Cyberinfrastructure Communities (GCI) - GMU
Scope The project is to develop open-source web portal to utilize the
GOS maps and data services to support Earth and geography science communities through the partnership of George Mason University’s Joint Center for Intelligent Spatial Computing (CISC), the Federation of Earth Science Information Partnership (ESIP), and the Cyberinfrastructure Specialty Group (CISG) within the American Association of Geographers (AAG).
Outcomes– An open source Spatial Web Portal connecting to GOS development
document and user manual– A category of over 20,000 WMS layers from GOS and other
communities.– Serve ESIP, AAG CISG, and NASA Earth Science Communities

Project Background and Scope Core Partners:
Innovate!, Inc. Environmental Protection Agency (EPA) Coeur D’Alene Tribe (CDA) North Carolina Department of Environment and Natural
Resources (NCDENR) Created software that extends GOS services to include
new partners and features Called GeoFinder for the Environment (GFE) Extends GOS Capabilities through web-based API that
connects numerous distributed catalogs Provides numerous output formats and input parameters Core partners implemented the API for use in their
organizations Integration within EPA Earth (KML Output) Integration within CDA Tribe GIS Home Page (DHTML
Output) Provided free training to interested parties
45 participants: States, Federal Agencies, Tribes, Others
GeoFinder for the Environment
Key Software Features
Metadata search and discovery tool Federated search model Supports many catalog implementations Easy to plug into new partner catalogs
Basic Components Web based front end Simple, URL-based API (more detail in upcoming slides) Easy to use outputs and parameters
Extends GOS Extends the basic capabilities of GOS Targeted catalog search (GOS, States, etc.) Additional capabilities to customize output
