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 – July 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

 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 GFE Capabilities

*Note: not all capabilities currently being used

 Accessing the GFE:  Web Interface:  Can be used as a basic search and discovery interface  Can also be used as a test environment for constructing API URLs  API Base URL:  API Parameters:  SearchServices (target specific catalog provider)  Michigan GIS = MI_GIS  MN Land Management = MN_LMIC  MN Dept of Natural Resources = MN_DNR  MN Metro GISMN_MGIS  Geospatial One Stop = GOS2  GEOSS = GEOSS  GMU One Geology = GMUOneGeology  Keywords (specify the keywords you’re looking for)  f (output format: kml, georss, html, html_static)  &f=html &f=html GFE Capabilities
