Sentinel5P filtering products
Answer

Dear support administrator,

I am sending the following request to your Finder API server


1
https://finder.creodias.eu/resto/api/collections/Sentinel5P/search.json?&startDate=2019-01-29T00%3A00%3A00&completionDate=2019-01-30T00%3A00%3A00&status=all&dataset=ESA-DATASET&geometry=POLYGON%20%28%2836.58099999999999%20-0.5430000000000064%2C%2036.639%20-0.7170000000000023%2C%2036.699%20-0.6969999999999974%2C%2036.64099999999999%20-0.5230000000000015%2C%2036.58099999999999%20-0.5430000000000064%29%29&product=L2__CLOUD_

My request expects a server response with only results representing the "geolocated cloud and aerosol information (e.g. absorbing aerosol index and aerosol layer height)" however my response includes other products as well.

Can you please help me understand why this is the case?

PS. In your Finder API schema I cannot find a collection for the
Copernicus Land Monitoring Service (CLMS) - is these data accessible through your Finder API?

Kind regards,
D.

Dear Dimitrios,

In CREODIAS Finder products should been searched by using parameter "productType", not "product".
Proper query should look like that:
1
https://finder.creodias.eu/resto/api/collections/Sentinel5P/search.json?&startDate=2019-01-29T00:00:00&completionDate=2019-01-30T00:00:00&status=all&dataset=ESA-DATASET&geometry=POLYGON ((36.58099999999999%20-0.5430000000000064, 36.639 -0.7170000000000023, 36.699 -0.6969999999999974, 36.64099999999999 -0.5230000000000015, 36.58099999999999 -0.5430000000000064))&productType=L2__CLOUD_
CLMS will be available in the next few days, however products will not be listed in CREODIAS Finder.
You can access CLMS by setting up VM in CREODIAS and connecting with EOData via s3 or NFS.

Hi Mateusz,

Thanks for the quick response and amending the request with the right URL parameter. I can confirm that your URL works as expected. Can you point me to the documentation summarising your API schema please?

Also thanks for clarifying the availability and access for CLMS - I was expecting that this would be available from your Finder API because of the information mentioned in he following URL: https://discovery.creodias.eu/dataset/copernicus-land-monitoring-service-clms

Thanks again,
D.

Hi Dimitrios,

I attach three links with the documentation:

1.EO DATA Finder API Manual -> it's most comprehensive guide to clarify our whole API concept:
https://creodias.eu/eo-data-finder-api-manual?inheritRedirect=true

2.Freshly implemented ordering of processed product:
https://finder.creodias.eu/api/doc/

3.Shortened version of documentation pointed above + guide "How to obtain a Keycloak token":
https://creodias.eu/-/how-to-order-products-using-finder-api-


Please tell us if you need more docs. We'll try to deliver a proper FAQ directly to your area of interest.

Kind regards,

Hi Mateusz,

Again thanks for your assistance with this - I think the Finder API documentation is a good first attempt but my suggestion would be to have a similar API like the one found at `https://finder.creodias.eu/api/doc/`.

Going back to the "Copernicus services" my understanding was that these services woud also be freely available through the DIAS APIs - why is it the case that only paying customers can access the data through your VM offering? Is there a ETA for Copernicus services through your API?

Kind regards,
D.

Hi Dimitrios,

CREODIAS platform's main purpose is to facilitate processing of the Copernicus products.
We collect the products on our storage and users can easily process them implementing algorithms on virtual machines using NFS or S3 protocols.
Thus you don't have to download the products and this speeds up the processing distinctly.
Additionally you can download most of the products from our platform to your desktop.
You can also download all the products from the source: Copernicus Open Access Hub.

Best regards,

Hi Marcin,

Thanks for your reply and context.

I suppose what I am trying to understand is whether you are planning to have the "Copernicus products" found at https://www.copernicus.eu/en in your Finder API anytime soon - from the announcement introducing the DIAS my understanding was that all Copernicus products would be freely downloadable at some point through the DIAS platforms.

I understand how your VM/S3 model works and I am planning to explore it soon because I can clearly see the benefits that you describe in your message.

Kind regards,
D.
