Using the Copernicus Open Access Hub for searching and downloading Copernicus Sentinel data is the default option. The following product types (parameter producttype) are currently supported for download from the Copernicus Open Access Hub:
To connect to the Copernicus Open Access Hub both a user name and password are required; see Register new account page for signing up.
The following product types (parameter producttype) are currently supported for download from the USGS Earth Explorer:
To connect to the USGS Earth Explorer both a user name and password are required; see EROS Registration System page for signing up.
The following product types (parameter producttype) are currently supported for download from Google Cloud Storage:
i.sentinel.download reads the user credentials from the settings file. The file must contain at least two lines:
myusername mypassword
User credentials can be also defined interactively when settings=- is given. Note that interactive prompt does not work in the graphical user interface.
Insert username: myusername Insert password: Insert API URL (leave empty for https://scihub.copernicus.eu/apihub):
By default Sentinel products are sorted by cloudcoverpercentage and ingestiondate (see sort option). By default, only products which footprint intersects current computation region extent (area of interest, AOI) are filtered. The AOI can be optionally defined also by vector map. In addition the spatial relation between AOI and the footprint (area_relation) can be set to
i.sentinel.download limits the default search for products to the last 60 days; an exact date range can be defined by start and end parameters to search beyond that.
Sentinel products can be also filtered by producttype or, in case of Sentinel-2 data, maximum clouds cover percentage.
Extra search keywords can be specified with query. Multiple keywords can be listed separated with comma (e.g. 'polarisationmode=VV,orbitdirection=Ascending'). Note that ESA maintains a list of valid search keywords that can be used with query. Usage of the query option for searching and downloading from the USGS Earth Explorer allows the keywords identifier and filename, both in ESA format. Additionally, the keyword usgs_identifier can be used to search for a specific scene in USGS name format (see USGS Entity ID)
i.sentinel.download also allows downloading of Sentinel products by specifying a (list of) UUID. This operation is performed by the uuid option. Note that this option is mutually exclusive with all other filtering options. The format of UUID differs between the Copernicus Open Access Hub and the USGS Earth Explorer (see examples below).
In case a Sentinel data download was interrupted, i.sentinel.download will continue to download once the command is restarted and the partially downloaded file (with .incomplete file extention) still present.
The output directory is created if not yet available.
The query string sent to ESA can be shown with --verbose.
As an alternative to triggering re-upload Sentinel-2 data from the LTA, scenes can be downloaded from USGS Earth Explorer or Google Cloud Storage where all data remain online and directly accessible. However, this applies only to Sentinel-2 data in levels 1C (USGS and GCS) and 2A (only GCS).
