  1. DMAC ST and the Activities of the IOOS PO Derrick Snowden DMAC Steering Team 2013-02-28

  2. The recent IOOS summit issued a few recommendations or challenges wrt DMAC • Clear instructions on how to participate • Define a way to measure progress Presentation Objective Recent progress and near term plans for IOOS in the context of these two challenges

  3. Great, a challenge, now what? • Clear instructions to participate – (in what?) • Metrics for progress – (towards what?) http://manicdepressiveblog.wordpress.com/2011/05/05/manic-depressive-illness-confusion-and-fear-of-sanity/

  4. There are several valid descriptions of “what” DMAC is GEOSS Architecture AIP-6 EarthCube Concept Groups esp. Layered Architecture Cross Domain Interoperability NOAA Environmental Data Management Framework (v0.4) Alternatively, these are efforts to define the scope of the system we need.

  5. IOOS IOOS IOOS Clients IOOS IOOS Discovery Service Access Service

  6. The trouble with catalogs… IOOS GEOSS WMO WIS data.gov One of the summit requests was for metrics to measure progress and community catalogs offer one possibility to focus on. More and better data services, more and better tools to use data, all data and tools registered in a catalog somewhere. Illustrates the Publish, Find, Bind Pattern. OGC Reference Model (OGC 08-062r7)

  7. Metrics: Registry Inventories, quantity • GEOSS – 286 services • IOOS - 239 records • NODC - 26778 records • NGDC - 22469 records • NCDC - 283 records • NASA PO.DAAC - 381 datasets https://www.ngdc.noaa.gov/metadata/published/NOAA/IOOS/iso/index-secure.html

  8. Metrics: Registry Inventories, quality • ISO 19115 metadata completeness, internal consistency, accuracy https://www.ngdc.noaa.gov/metadata/published/NOAA/IOOS/iso/index-secure.html

  9. Another viewpoint on maturity and measuring progress

  10. Clear directions for participating • Guidelines for implementing a IOOS profile of SOS (http://ioostech.googlecode.com)

  11. Tools to make it easier: Servers • THREDDS 4.3 released (Unidata) • ncISO continued support • ncSOSnew release • Continued development on triangular mesh grids • 52North SOS implementing IOOS Profile • SciWMS – Open source WMS server optimized for large netCDFdata sets with some curvilinear grid support

  12. ncSOS: SOS Service on top of THREDDS • Open source plugin for TDS • Maps CF (v1.6) Discrete Sampling Geometries to SWE Common SOS response types • Wiki with installation instructions, compatible data sets and hints for use (http://asascience-open.github.com/ncSOS/) • USGS fork at https://github.com/USGS-CIDA/ncSOSx

  13. 52North.org SWE tools • Adopted SOS service and modified to support IOOS Profile (beta released, needs testers) • SOS2NC Archiver tools (periodic dump to NODC netcdf templates) • Implicit QC routines built in to SOS • 52North OXF Web Client

  14. Tools: Clients • Python library for SOS • Java-netCDF IOSP for SOS output • Java SWE parsing library • ncToolbox: Matlab library for CF-netCDF and soon SOS/SWE • Python based CF netCDF compliance checker • Javascript SOS client • Environmental Data Connector
