== Overview ==
 +
 
 +
[[Earth_Observation_Data_Management_System_(EODMS)|EODMS]] has several options for search and download API access as well as automation i.e. Machine 2 Machine.
 +
 
 +
As part of the [https://www.tbs-sct.gc.ca/pol/doc-eng.aspx?id=28108 Directive on Open Government], the Government of Canada is committed to improving its [https://twitter.com/hashtag/opendata?lang=en #OpenData] posture. EODMS API access aims to promote practices per the [https://www.canada.ca/en/government/system/digital-government/modern-emerging-technologies/government-canada-standards-apis.html GC Standards on APIs]

Default result format is human-readable HTML. Appending <code>&format=json'</code> or <code>'=xml'</code> to the URL behaves as expected.

== OPENSEARCH API. Copernicus Hub Inspired. Provides Direct Download. RADARSAT-1 and NAPL, ONLY) ==
 +
 +
This particular flavour of OpenSearch API is heavily modeled after the [[https://scihub.copernicus.eu/userguide/OpenSearchAPI Copernicus Data Hub OpenSearch access program]] to align RADARSAT-1 and NAPL access with SENTINEL access. Each API response comes with a direct download URL (in contrast to the [[#REST Order|REST Order]] API call which invokes a slower archive-pull-and-stage operation.

&#x09;&#x09;&#x09;&#x09;radar(SAR) imaging instrument. The images are used internationally

&#x09;&#x09;&#x09;&#x09;climate change, as well as in many other commercial and scientific

&#x09;&#x09;&#x09;&#x09;applications. RADARSAT-1 is ideally suited to supporting these

&#x09;&#x09;&#x09;&#x09;tasks because of its wide range of beams, SAR technology, frequent

 +
&#x09;&#x09;&#x09;&#x09;Radarsat-1 also has the unique ability to direct its beam at
