Context
As mentioned in this article, the WEkEO DIAS provides multiple Earth Observation data from Sentinel missions.
When downloading data via the HDA API , some parameters (mandatory or optional) 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 download data from the Expert Data Viewer, 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
hda_client = Client()
hda_client.metadata(dataset_id)
⚠️ This present list is not exhaustive: please contact the User Support if you encounter an issue with another parameter not listed below.
