EODMS APIs (and automation)[edit | edit source]
EODMS is has several options for API Access and automation i.e. Machine 2 Machine. To find more GC APIs, visit the GC API site.
https://api.canada.ca/en/homepage
As part of the Directive on Open Government, the Government of Canada is committed improving its #OpenData posture.
OpenSearch API (for RADARSAT-1 and NAPL)[edit | edit source]
This OpenSearch API is the latest effort to align with giants like ESA and their [Copernicus Data Hub OpenSearch access program] to improve RADARSAT-1 access
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=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.
Heavily modeled after the ESA Data hubs so the following should apply:

OGC APIs[edit | edit source]
See File:EODMS OGC Services.pdf for complete details as well as an end-to-end sample.
Searching with OGC Catalog Services for the Web (CSW)[edit | edit source]

The images are used internationally to manage and monitor the Earth's resources and to monitor global climate change, as well as in many other commercial and scientific applications. RADARSAT-1 is ideally suited to supporting these tasks because of its wide range of beams, SAR technology, frequent revisit period, high-quality products and fast, efficient delivery. Each of Radarsat-1's seven beam modes offer a different image resolution. The modes include Fine, which covers an area of 50 km × 50 km (31 mi × 31 mi) (2,500 km2 (970 sq mi)) with a resolution of 10 metres (33 ft); Standard, which covers an area of 100 km × 100 km (62 mi × 62 mi) (10,000 km2 (3,900 sq mi)) and has a resolution of 30 metres (98 ft); and ScanSAR wide, which covers a 500 km × 500 km (310 mi × 310 mi) (250,000 km2 (97,000 sq mi)) area with a resolution of 100 metres (330 ft). Radarsat-1 also has the unique ability to direct its beam at different angles.</dct:abstract><ows:BoundingBox><ows:LowerCorner>32.664853 -3.055419</ows:LowerCorner><ows:UpperCorner>33.172058 -2.442097</ows:UpperCorner></ows:BoundingBox></csw:SummaryRecord> ... </SearchResults> </GetRecordsResponse>
