1 What is ECHO? HTTP-based Search and Ordering Using ECHOs REST and OpenSearch APIs https://api.echo.nasa.gov/catalog-rest/catalog-docs/index.html How Can I Use It? ECHO Facts NASAs Earth Observing System ClearingHOuse (ECHO) acts as the core metadata repository for NASAs 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-compliant OpenSearch implementation Available Collections Over 100 million Granules 34 million ECHO hosted Browse Images 2TB Data Index Covers Petabytes of Data 60K+ registered users, utilizing EOSDIS URS 13 Active Data Partners Several Clients in Test & Evaluation LANCE Near Real Time Data Available Collections Over 100 million Granules 34 million ECHO hosted Browse Images 2TB Data Index Covers Petabytes of Data 60K+ registered users, utilizing EOSDIS URS 13 Active Data Partners Several Clients in Test & Evaluation LANCE Near Real Time Data ECHO and REST ECHO and OpenSearch Documentation and Support ECHOs RESTful Data Discovery allows users to filter collections and granules based on keywords, spatial and temporal extent platforms, instruments, processing level, campaign, and many other fields. It also allows for the filtering of granules by collection-specific attributes. Client developers can programmatically sort and page through both collection and granule results and may retrieve metadata in multiple formats including: ECHO10 ISO19115 (preliminary) JSON Atom (+FROST) csv (granules only) ECHOs RESTful Data Discovery allows users to filter collections and granules based on keywords, spatial and temporal extent platforms, instruments, processing level, campaign, and many other fields.

ECHO provides standards- based access to its public catalog through an implementation of OpenSearch. ECHO supports both the georss and time extensions as well as providing ECHO-specific extensions for fields such as line, point, instrument and provider name.
