[[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.

Checkout out our [https://github.com/nrcan-eodms-sgdot-rncan/eodms-ogc-client-py/wiki open source Python module on GitHub] which uses the CSW, WCS and REST APIs to automate the ordering of images from EODMS.

SEARCH FIELDS

 +
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.

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
