  1. Overview and demo of the Coastal Marine Discovery Service (NASA ACCESS 2009) Ed Armstrong – PI Luca Cinquini Chris Mattmann NASA Jet Propulsion Laboratory Frank O’Brien Zach Siegrist System Science Applications, Inc. 18 July 2012 ESIP Summer 2012 Madison, WI

  2. Overview . . . • AKA “Coastal Marine Discovery Service” (CMDS) • 1: a discovery portal for remote coastal datasets including satellite, in situ, ocean model, GIS layers. • No data stored in CMDS; only harvested metadata and URLs • http://cmds.jpl.nasa.gov • 2: a visualization and data interrogation system for datasets in the CMDS repository • “on the fly” visualization and georeferencing • Dataset overlay and download • Client web interface. No software necessary to download.

  3. Overview • CMDS blends proven software technologies of open source Solr/Lucene database and search interface with OODT and EASy GIS Netviewer from System Science Applications (SSA, see http://runeasy.com) • Discovery through a faceted and free text search interface • OODT is used extensively (profile servers, profile handlers) to parse and ingest the remote datasets • OODT harvests Catalog.xml from THREDDS servers • Visualization and interrogation via EASy Netviewer • Web client • Interacts directly with search results from CMDS (URLs) to access and download data

  4. CMDS accessible data • Satellite: Level 2,3 and 4 products for SST, Chl A, Turbidity, Wind, SSH, Salinity • Ocean Models: 3D Salinity, Depth, Temperature and Currents • Currents: Coastal HF Radar • In situ data: Ship, buoy, and glider observations of SST, Wind and Currents • Historical: CalCOFI reports, fish surveys, scientific cruises • GIS coverages and other point data: Bathymetry, marine sanctuary boundaries, socio-economic

  5. Architecture (from proposal)

  6. Metadata harvesting/ingestion pipeline

  7. CMDS web site (public)

  8. CMDS search interface • Facet/free text driven to over 160 data sets • To date focused on coastal datasets from CoastWatch, NOAA ERDDAP, NASA PO.DAAC, NOAA NODC, NVODS, US NAVY on THREDDS (OPeNDAP) servers • Interface built on the earth system grid federation software

  9. Visualization and data interrogation – the EASy NetViewer client • Reads and displays any OPeNDAP URL from CMDS catalog • Data interrogation of pixel values • ROI statistics • GIS like queries (filtering, stats) between multiple layers • Hardwired shapefile layers • Data export to netCDF3

  10. Integration • Future deployment at PO.DAAC “labs” site Aug 2012: • Site for exposure of new tools and services • Based on user feedback will be elevated to a standard PO.DAAC service

  11. Acknowledgements • The work described was performed at the Jet Propulsion Laboratory, California Institute of Technology, under contract to the National Aeronautics and Space Administration for ROSES ACCESS 2009.

  12. Current architecture

  13. Issues • Latency to periodically recrawl previously indexed data repositories • Many THREDDS repositories have extremely limited granule metadata • Free text search interface suffers

  14. Example of a NVODS dataset with limited metadata
