Overview[edit | edit source]

As part of the Directive on Open Government, the Government of Canada is committed improving its #OpenData posture. This OpenSearch API is the latest effort to align the Earth Observation Data Management System (EODMS) with giants like ESA and their [Copernicus Data Hub OpenSearch access program] to improve RADARSAT-1 access

Examples[edit | edit source]

To form a get query it would take the form of:

https://data.eodms-sgdot.nrcan-rncan.gc.ca/api/dhus/v1/products/Radarsat1/search?q={searchterms}

e.g.:

https://data.eodms-sgdot.nrcan-rncan.gc.ca/api/dhus/v1/products/Radarsat1/search?q=footprint:Intersects((-130.496,54.672))

https://data.eodms-sgdot.nrcan-rncan.gc.ca/api/dhus/v1/products/Radarsat1/search?q=beginposition:[2007-08-20T00:49:50Z%20TO%202007-08-22T10:50:50Z]

Search Terms

producttype which can be SCN,SGF, or SLC for Radarsat-1
sensoroperationalmode which refers to the beam mnemonic like EH3, F1, W2, SCWB, SCNA etc..
polarisationmode which is only HH for R1
ingestiondate
beginposition
endposition
footprint  (point and polygon)

The search terms can be used together with AND and OR. There is also support for wildcards, free text searching and other operators:

Wildcard	Description

*		any sequence of zero or more characters
?		any one character
Operator	Description

AND	        Narrow search and retrieve records containing all of the words it separates.
OR		Broaden search and retrieve records containing any of the words it separates.
NOT		Narrow search and retrieve records that do not contain the term following it.
( )		Group words or phrases when combining Boolean phrases and to show the order in which relationships should be considered.
