OpenSearch Description Document

In OpenSearch, you can get description of a first level of information called Step 1, which is at the top level of the available collections. Then from the result of the Step 1, you can get detailed information of a collection which called Step 2. The two next sections present these steps 1 & 2. It is worth noting that, the OpenSearch Description Document (OSDD) can change according to new collections implemented in ONDA catalogue, and values presented hereunder, can be modified accordingly. You should request the OSDD (Step 1 & 2) regularly to check and update your application according to ONDA catalogue updates.

Use of the OpenSearch filters – Step 2

OpenSearch filters

SearchTerm can contains wildcards like ? or * and can be mixed with other logical operators, like AND or OR.

Examples:

e.g: Get product by platformShortName and instrumentShortName

https://catalogue.onda-dias.eu/opensearch/OpenSearch?searchTerms=platformShortName:S2%20AND%20instrumentShortName:MSI

Search Sentinel-1A or Sentinel-2A products

https://catalogue.onda-dias.eu/opensearch/OpenSearch?searchTerms=name:S1A*%20OR%20S2A*

[alternatively]

https://catalogue.onda-dias.eu/opensearch//OpenSearch?searchTerms=name:S1A*%20OR%20name:S2A*

Search a product by its identifier

Objective: Retrieve metadata for one product according to its product identifier

<ONDA:resourceAbstract>

The Level-1C product is composed of 100×100 km2 tiles (ortho-images in UTM/WGS84 projection). The Level-1C product results from using a Digital Elevation Model (DEM) to project the image in cartographic geometry. Per-pixel radiometric measurements are provided in Top Of Atmosphere (TOA) reflectances along with the parameters to transform them into radiances. Level-1C products are resampled with a constant Ground Sampling Distance (GSD) of 10, 20 and 60 m depending on the native resolution of the different spectral bands. In Level-1C products, pixel coordinates refer to the upper left corner of the pixel. Level-1C products will additionally include Cloud Masks and ECMWF data (total column of ozone, total column of water vapour and mean sea level pressure)

Sorting results

The list of results can be sorted using “sortKeys” and can be arranged in descending order (desc) or ascending order (asc).

Example:

Search products where platformName=Sentinel-2 and productType=S2MSI1 with creationDate arranged in descending order

https://catalogue.onda-dias.eu/opensearch/OpenSearch?platformName=Sentinel-2&productType=S2MSI1C&sortKeys=creationDate%2C%2Cdesc

Paging results

A query can be completed with the pagination options, using startIndex and count.
Please note that the default number of records returned in a single query is set to 25.

Search products with creationDate in a specific time range (from record 1 to 25, by default):

https://catalogue.onda-dias.eu/opensearch/OpenSearch?creationDate=[2021-02-22T00:00:01Z%20TO%202021-02-22T01:00:01Z]

Search products with creationDate in a specific time range (from record 2 to 26, using startIndex):

https://catalogue.onda-dias.eu/opensearch/OpenSearch?creationDate=[2021-02-22T00:00:01Z%20TO%202021-02-22T01:00:01Z]&startIndex=2

Search products with creationDate in a specific time range (the first 5 records, starting from record 2)

https://catalogue.onda-dias.eu/opensearch/OpenSearch?creationDate=[2021-02-22T00:00:01Z%20TO%202021-02-22T01:00:01Z ]&startIndex=2&count=5

Search products with creationDate in a specific time range (100 records):

https://catalogue.onda-dias.eu/opensearch/OpenSearch?creationDate=[2021-02-22T00:00:01Z%20TO%202021-02-22T01:00:01Z ]&count=100

How to get number of records for a requested

Like any other OpenSearch request, it is possible to set the request to return only the number records corresponding to the request. Set the value of the count parameter to 0 (zero) in your request, like hereunder:
