1. What is ECHO? ECHO Open Search https://api.echo.nasa.gov/opensearch ECHO Facts NASA’s Earth Observing System ClearingHOuse (ECHO) acts as the core metadata repository for NASA’s Earth Observing System Data and Information Systems data centers, providing a centralized mechanism for metadata and data discovery and retrieval. ECHO has recently made strides to restructure its API; allowing data partners to streamline and synchronize their metadata ingest using RESTful web services as well as providing an ESIP and OGC compliant OpenSearch implementation. 3500+ Available Collections 3500+ Available Collections Over 120 million Granules Over 120 million Granules 41 million ECHO hosted Browse Images 41 million ECHO hosted Browse Images 2TB Data Index Covers Petabytes of Data 2TB Data Index Covers Petabytes of Data 78K+ registered users, utilizing EOSDIS URS 78K+ registered users, utilizing EOSDIS URS 13 Active Data Partners 13 Active Data Partners Several Clients in Test & Evaluation Several Clients in Test & Evaluation LANCE Near Real Time Data LANCE Near Real Time Data 3500+ Available Collections 3500+ Available Collections Over 120 million Granules Over 120 million Granules 41 million ECHO hosted Browse Images 41 million ECHO hosted Browse Images 2TB Data Index Covers Petabytes of Data 2TB Data Index Covers Petabytes of Data 78K+ registered users, utilizing EOSDIS URS 78K+ registered users, utilizing EOSDIS URS 13 Active Data Partners 13 Active Data Partners Several Clients in Test & Evaluation Several Clients in Test & Evaluation LANCE Near Real Time Data LANCE Near Real Time Data ECHO and OpenSearch ESIP Federated Search, based on the OpenSearch convention, is a simple framework for doing a federated query among participating members for Earth science data. ECHO provides standards-based access to its public catalog through an implementation of OpenSearch.
