Line 1: − <multilang>@en| − == Overview == − − As part of the [https://www.tbs-sct.gc.ca/pol/doc-eng.aspx?id=28108 Directive on Open Government], the Government of Canada is committed improving its [https://twitter.com/hashtag/opendata?lang=en #OpenData] posture. This OpenSearch API is the latest effort to align the [[Earth Observation Data Management System (EODMS)]] with giants like ESA and their [[https://scihub.copernicus.eu/userguide/OpenSearchAPI Copernicus Data Hub OpenSearch access program]] to improve RADARSAT-1 access − − == Examples == − − To form a get query it would take the form of: − <pre> − https://data.eodms-sgdot.nrcan-rncan.gc.ca/api/dhus/v1/products/Radarsat1/search?q={searchterms} − </pre> − − e.g.: − <pre> − 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] − </pre> − − The valid search terms right now are: − <pre> − 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) − </pre> − − The search terms can be used together with AND and OR. There is also support for wildcards, free text searching and other operators: − − <pre> − Wildcard Description − − * any sequence of zero or more characters − ? any one character − </pre> − − <pre> − 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. − </pre> − − Heavily modeled after the ESA Data hubs so the following should apply: − https://colhub.copernicus.eu/userguide/OpenSearchAPI − − @fr| − − == Vue d'ensemble == − − Le gouvernement du Canada s'est engagé à améliorer sa posture #OpenData, et cette nouvelle API est le dernier effort visant à s'aligner sur des géants tels que l'ESA et leur programme d'accès Sentinel afin d'améliorer l'accès à RADARSAT-1. − − == Exemples == − − Pour former une requête get, cela prendrait la forme suivante: − <pre> − https://data.eodms-sgdot.nrcan-rncan.gc.ca/api/dhus/v1/products/Radarsat1/search?q={searchterms} − </pre> − − Par exemple: − <pre> − 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] − </pre> − − Les termes de recherche valides actuellement sont: − <pre> − producttype pouvant être SCN, SGF ou SLC pour Radarsat-1 − sensoroperationalmode qui fait référence à la mnémonique du faisceau comme EH3, F1, W2, SCWB, SCNA, etc. − polarisationmode qui n'est que HH pour R1 − ingestiondate − beginposition − endposition − footprint (point et polygon) − </pre> − − Les termes de recherche peuvent être utilisés avec AND et OR. Il existe également un support pour les caractères génériques, la recherche de texte libre et d'autres opérateurs: − − <pre> − Wildcard Description − − * any sequence of zero or more characters − ? any one character − </pre> − − <pre> − 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. − </pre> − − Ainsi, comme indiqué précédemment, il est fortement calqué sur les concentrateurs de données ESA: − https://colhub.copernicus.eu/userguide/OpenSearchAPI − </multilang>
