Canada Centre for Mapping and Earth Observation

Radarsat-2 Mission CCMEO operates ground receiving stations for Radarsat-2 scenes on behalf of the

Canadian Space Agency and other Federal departments CCMEO archives all raw image data and catalogues the metadata for these scenes

EODMS Catalogue Interoperability - OpenSearch CCMEO has implemented an OpenSearch server as part of its

ongoing commitment to be a CWIC data partner

CCMEO OpenSearch currently enables users to search the CCMEO Radarsat-2 catalog for Radarsat-2 raw scenes (systematically geocorrected) Metadata is provided as well as a links to the browse image and an order

page CCMEO OpenSearch be migrated to CCMEO’s next generation

catalogue/archive system – Earth Observation Data Managemen System (EODMS) (May2016)

Users can access CCMEO OpenSearch through the CWIC OpenSearch connector

Example : http://cwic.wgiss.ceos.org/opensearch/granules.atom?datasetId=CWIC_REG&clientId=CCMEO&timeStart=2015-05-17T07:14:55Z&timeEnd=2015-05-19T07:14:55Z&startPage=1&count=100

OpenSearch will also be enabled for the discovery of scenes from the Radarsat Constellation Mission (RCM) after launch in 2018

EODMS Catalogue Interoperability- NASA COVE tool The CEOS Visualization Environment(COVE) tool now harvests Radarsat-2

raw scenes from CCMEO via OpenSearch on a daily basis
