DESCRIPTION

The i.sentinel.download addon allows downloading Sentinel satellite products from the Copernicus Data Space Ecosystem.

Copernicus Data Space Ecosystem

Using the Copernicus Data Space Ecosystem 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 Data Space Ecosystem:

Sentinel-1 (SAR; available from Oct 2014 to present day) (SAR) products:
- SLC: Single Look Complex (Level-1)
- GRD: Ground Range Detected (Level-1)
- GRDCOG: COG format based Ground Range Detected (Level-1)
- OCN: Ocean products for wind, wave and currents applications (Level-2)
Sentinel-2 (optical and infrared; available from July 2015 to present day) (optical) products:
- S2MSI2A: operational Bottom-Of-Atmosphere reflectances in cartographic geometry Level-2A)
- S2MSI1C: Top-Of-Atmosphere reflectances in cartographic geometry (Level-1C)
Sentinel-3 (OLCI and SLSTR instrument data products at level 2, for OLCI sensor also Level 1; available from April 2018 to present day) (optical) products:
- S3OL1EFR: Land colour and atmosphere TOA radiances at full resolution
- S3OL1ERR: Land colour and atmosphere TOA radiances at reduced resolution
- S3SL1RBT: Brightness temperatures and radiances
- S3OL2WFR: Ocean colour, water and atmosphere geophysical parameters
- S3OL2WRR: Ocean colour, water and atmosphere geophysical parameters at reduced resolution
- S3OL2LFR: Land colour and atmosphere geophysical parameters
- S3OL2LRR: Land colour and atmosphere geophysical parameters at reduced resolution
- S3SL2LST: Land Surface Temperature
- S3SL2FRP: Fire Radiative Power
- S3SR2LAN: Land Surface Height
- S3SY2SYN: Surface Reflectance and Aerosol parameters over Land
- S3SY2VGP: 1 km VEGETATION-Like product (~VGT-P) - TOA Reflectance
- S3SY2VG1: 1 km VEGETATION-Like product (~VGT-S1) 1 day synthesis surface reflectance and NDVI
- S3SY2V10: 1 km VEGETATION-Like product (~VGT-S10) 10 day synthesis surface reflectance and NDVI
- S3SY2AOD: Global Aerosol parameter over land and sea on super pixel resolution (4.5 km x 4.5 km)

To connect to the Copernicus Data Space Ecosystem both a user name and password are required; see Register new account page for signing up.

Copernicus Open Access Hub (DEPRECTAED)

Copernicus Open Access Hub is now permanently closed. To continue accessing Copernicus Sentinel data, Copernicus Data Space Ecosystem is now the new successor.

Credentials file

i.sentinel.download reads the user credentials from the settings file. The file must contain at least two lines:

myusername
mypassword

NOTES

The data hub to download from can be indicated with the datasource option. ESA's Copernicus Data Space Ecosystem is the default, and currently only, option.

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

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

Contains: to only return scenes where the AOI is contained inside the footprint (Only supported by Copernicus Data Space Ecosystem)
IsWithin: to only return scenes where the footprint is contained inside the AOI (Only supported by Copernicus Data Space Ecosystem)
Intersects: to return all scenes where the footprint intersects the AOI (default)

Filtered products can be reduced by limit option.

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 S2MSI1C, S2MSI2A, S3SY2SYN, S3SY2VGP, S3SY2VG1, S3SY2VG1 and S3SY2AOD, maximum clouds cover percentage.

Extra search keywords can be specified with query. Multiple keywords can be listed separated with comma (e.g. 'polarizationChannels=VV&VH,orbitdirection=ASCENDING').

List of Some Queryables:

orbitNumber
timeliness (e.g. NT, NRT-3h, etc...)
processingBaseline
polarizationChannels (e.g. VV&VH)
storageStatus

Note refer to i.eodag to get a list of all queryables. Note that text based queryables have to be upper-case. Scenes with unavailbe queryable information are filtered out (e.g. if a product has the timeliness queryable set as Null, then it will be filtered out if you use query="timeliness=NT"). If a scene doesn't have a queryable as part of its metadata, the scene will be silently maintained without any warnings.

i.sentinel.download also allows downloading of Sentinel products by specifying a (list of) ID, where ID refers to the scene name on Copernicus Data Space Ecosystem. This operation is performed by the id option. Note that this option is mutually exclusive with all other filtering options. The id option also accepts text files with (list of) ID, one ID per line.

In case a Sentinel data download was interrupted, i.sentinel.download will restart the download for the paritally downloaded data, from scratch, once the command is re-excuted.

The output directory is created if not yet available. Default is current working directory.
