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 Sentinel 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/products/Radarsat1/search?q={searchterms}

Eg:

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

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

The valid search terms right now are:

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.

So as stated before it's heavily modeled after the ESA Data hubs so the following should apply:
