a selection of product components (e.g. spectral bands, standard/expert metadata,
preview image, auxiliary data, etc)
a selection of the output format (SAFE or DIMAP)
an optional extension of the granule selection such that the downloaded products
contain either (1) the sole granules selected, (2) all granules across the 290km MSI
swath overlapping the AOI or (3) the full parent product (orbit stripline).
S2-PDGS-MMUS-155
The MMUS function shall execute the download operations by triggering the Sentinel-2
specific DAG function client software hosted on the user computer, characterising for each
download operation:
the user authentication information (e.g. user credential);
the parent-product identifier;
the list of granules to compile;
the download options (list of product components & format);
a URL to the preview image or the preview image itself.
S2-PDGS-MMUS-160
The MMUS function shall allow the users to subscribe to the authorised datasets for
automatic product(s) download at the user-base. The user shall be able to subscribe from
one-to-n authorised datasets and be able to receive the products from different
subscriptions at different sink interfaces.
S2-PDGS-MMUS-165
The MMUS function shall be able to authorise every product download operation
performed by the DAG function via an authorisation service invoked at the effective
download time and to return the user priority for download assigned in the user profile;
S2-PDGS-MMUS-170
The MMUS function shall systematically record the qualified status provided by the DAG
function on completion of every download request (volumes downloaded, download
performance, etc) to allow the periodic generation of data-access statistics.
S2-PDGS-MMUS-175
The MMUS function shall allow authorised users to trigger hosted-processing requests.
Accordingly it shall allow the user to define the processing parameters, trigger the
processing, follow-up the status of the request since the submission until completion, and
perform the resulting product download.
S2-PDGS-MMUS-180
The MMUS function shall allow authorised users to trigger, monitor and manage hostedprocessing
requests via an HMI.
