As mentioned in this article, WEkEO DIAS provides several observation data from Sentinel missions.
When downloading via HDA, certain (mandatory and optional) parameters are required for the query to be processed.
Changes in the API endpoint for access to Sentinel data is being deployed and the WEkEO HDA is being updated to reflect that change. A script update of some parameters is therefore required.
📌Note: if you only use HDA access from the Data Viewer (how-to), the parameters are already updated and no further action is needed.
Let's see which parameters are changing, according to the Sentinel mission.
💡WEkEO Pro Tip: only changed parameters are listed below; if a parameter is not specified, no change has been applied. If you are not sure and/or you face an issue, you can double check the parameters by calling the metadata() function for the dataset_id of interest:
from hda import Client
c = Client()
c.metadata(dataset_id)
⚠️ This present list is not exhaustive: please contact the WEkEO Support if you encounter an issue with another parameter not listed below.
