ECHO FactsNASA’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.

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.

ECHO Open Search supports the following standards,• OpenSearch 1.1• ESIP Discovery 1.2• OGC® OpenSearch GeoSpatial and Temporal Extensions OGC 10-032r3

Datasets and granules can be queried using the following constraints,• keywords (dataset only)• spatial (bounding box, geometry, place name)• temporal (start, end)• instrument (dataset only)• short name (granule only)• version ID (granule only)

How Can I Use It?

OpenSearch Description Documents (OSDDs):https://api.echo.nasa.gov/opensearch/datasets/descriptor_document?client_id=dughttps://api.echo.nasa.gov/opensearch/granules/descriptor_document?client_id=dug

Granule search:

curl "https://api.echo.nasa.gov/opensearch/granules.atom? clientId=dug& shortName=MOD02QKM&versionId=5& dataCenter=LAADS& boundingBox=-180.0%2C-90.0%2C180.0%2C90.0& startTime=2002-05-04T03A00-04%3A00& endTime=2009-05-04T00%3A00%3A00-04%3A00& numberOfResults=10&cursor=0”

Granule result:

<?xml version="1.0" encoding="UTF-8"?> <feed esipdiscovery:version="1.2" xmlns="http://www.w3.org/2005/Atom" xmlns:esipdiscovery="http://commons.esipfed.org/ns/discovery/1.2/" xmlns:os="http://a9.com/-/spec/opensearch/1.1/">
