ECHO Overview and State of the System

The ECHO system, managed by NASA’s EOSDIS, is essential for monitoring daily events and long-term environmental changes through over 3,500 data types. This presentation highlights the metadata and functionalities of ECHO, focusing on data collection, processing, and retrieval services. Attendees will learn about its web front end, data ordering, spatial and temporal searches, and the integration of new data collections. Metrics and user engagement statistics will also be shared to illustrate ECHO's impact and ongoing developments in data accessibility and visualization.

  1. ECHO Overview and State of the System ESIP Winter Meeting 2014 Katie Baynes NASA ECHO Team kathleen.baynes@nasa.gov

  2. ESIP Winter 2014 ECHO System Overview

  3. What Metadata? • NASA’s Earth Observing Satellites (EOS) monitor daily events and long term environmental changes • EOSDIS data collection includes over 3,500 data types • Land • Cover & Usage • Surface temperature • Soil moisture • Surface topography • Atmosphere • Winds & Precipitation • Aerosols & Clouds • Temperature & Humidity • Solar radiation • Ocean Dynamics • Surface temperature • Surface wind fields & Heat flux • Surface topography • Ocean color • Cryosphere • Sea/Land Ice & Snow Cover • Human Dimensions • Population & Land Use • Human & Environmental Health • Ecosystems

  4. Reverb • ECHO’s web front end • Novices and Experts • Searching • Temporal • Spatial • Keywords • Platforms/Instruments/Sensors • Processing Level • Ordering • Downloads • Services • Sub-setting • Re-projection http://reverb.echo.nasa.gov/reverb

  5. Metadata Ingest • ECHO 10 Data Provider • ISO 19115 Data Provider Data Provider Ingest Both Collection and Granule Level • FTP Ingest • ISO 19115 Data Provider • ECHO 10 Data Provider • Format X • REST API • ECHO Catalog

  6. Search and Metadata Retrieval • Reverb • CWIC • Giovanni • … Client Data Retrieval • ESIP • OpenSearch • Direct • Clients • Searching • Ordering • Multi-format Retrieval • ECHO10 • JSON • ISO 19115 • REST API • ECHO Catalog

  7. ESIP Winter 2014 Operational Statistics and Interesting Metrics

  8. Some ECHO Stats • Central EOSDIS Metadata Repository • Holdings • 3830 Collections • 142 Million Granules • Client Applications • Reverb • ASTER Volcano Group • GHRC Data Albums Access • OpenSearch Clients (CWIC, et al) • GIBS • Non-self-identifying clients (aka ‘Other’)

  9. How Much Traffic Does ECHO See?

  10. GHRC/UAH Data Albums work in full swing ~650k queries

  11. Who’s Using ECHO?

  12. How Fast is ECHO?

  13. Adding More Interesting Metrics …

  14. Composite Reverb spatial search heat map for the last year

  15. Looking at How People are Using Reverb …

  16. ECHO Continues to work on Serving the Right People with the Right Tools

  17. ESIP Winter 2014 WHATS BEEN GOING ON?

  18. High Level Overview (Roughly Chronological) • ECHO Technical Interchange – Spring 2013 • NRT Data • Order Workflow Re-Work • Indexing Landsat 8 Data • Revisiting User Settings • ISO Activities • More!

  19. ECHO Technical Interchange http://fc04.deviantart.net/fs43/f/2009/099/8/5/CAT_PARADE_by_dolle.png

  20. ESIP Winter 2014 LANCE NEAR REAL TIME INdexing

  21. Current NRT Holdings (with GIBS!) * - Granules aged off after 7-10 days ** - Daily images not currently aged off

  22. Exposing ECHO’s NRT Holdings In Reverb Visual Indicators Quickly Call Out NRT Collections

  23. Discovering NRT in ECHO • Extending our Data Model and API • Metadata Element • API Query Parameter

  24. ESIP Winter 2014 ONGOING WORK

  25. Revisiting Ordering Workflows

  26. Indexing New Data Collections

  27. More Visualization Options … Pre-WRS-2

  28. Revisiting User Settings

  29. ISO19115 and ECHO • Following activities of NASA’s MENDS Study • Incorporating updated data translations • Learning more about community use and adoption • Working with this guy • Ingest of New Products inISO19115/19139
