Tool to download Sentinel data from ESA (through wget) (http://olivierhagolle.github.io/Sentinel-download)
The ESA Sentinel distribution website allows you to perform catalog searches through http requests. This blog post shows a few examples.
This module searches the ESA apihub catalog and downloads the products which fit the criteria defined in the command line. You can select by :
- coordinates of a point, or of a rectangle
- path number (sometimes, a point can be observed from several paths
- date, of course
This tool was written thanks to ESA well documented scihub API : https://scihub.esa.int/userguide/5APIsAndBatchScripting
To use it, you need wget installed. I guess it goes with any linux distribution. For windows, I don't know, but maybe someone can tell. If your download stops for a network issue, you can restart S2-download, as wget knows how to resume without havind to download everything again. Wget doesnot download the products already fully downloaded (unlesss you have unzipped them).
In case your download must be done through a proxy, you have to setup the https_proxy variable in your.bashrc file or in your .profile.
Proxy with password :
export https_proxy = http://uname:[email protected]:8080
Proxy without password :
export https_proxy = http://proxy.truc.fr:8080
Here are a few examples for Sentinel-2
- To download all the products over Toulouse
python %s --lat 43.6 --lon 1.44 -a apihub.txt (scene)"%sys.argv[0]
- To download all products over Toulouse taken from Path 51
python Sentinel_download.py --lat 41.6 --lon 1.44 -a apihub.txt -o 51 -s S2
- To see all products over Toulouse taken from Path 51, but without downloading, thanks to -n option
python Sentinel_download.py --lat 41.6 --lon 1.44 -a apihub.txt -o 51 -n -s S2
- To see all products in a rectangle and download only those with a small percentage of clouds :
python Sentinel_download.py --latmin 43 --latmax 46 --lonmin -1 --lonmax 2 -a apihub.txt -o 94 -m 23 -d 2015-12-06 -n -s S2
- to download all products above Toulouse downloaded after 2015-12-06
python Sentinel_download.py --lat 46.6 --lon 1.44 -a apihub.txt -o 94 -d 2015-12-06 -s S2
- you may also change the output directory with the -w option
python Sentinel_download.py --lat 46.6 --lon 1.44 -a apihub.txt -o 94 -d 2015-12-06 -w /mnt/data/Sentinel-2/ -s S2
- To download Sentinel-1 SLC products above a rectangle in France
python Sentinel_download.py --latmin 43 --latmax 46 --lonmin -1 --lonmax 2 -a apihub.txt -n -s S1A*SLC
- for other examples see Sentinel-2 examples
The scihub site accepts the "guest" account and "guest" password, as provided in the apihub.txt file. But only two downloads at the same time are allowed worldwide on the same account. So do not forget to enter your own account and password in the password file provided in the -a option.
However, please also note that ESA has currently limited the acces to users registered some time ago.
In December :
The API Hub Access is currently available only for users registered before the 20th of November 12:00 UTC, the user credentials as of the 20th November are valid to access this site.
In January : The API Hub Access is currently available only for users registered on SciHub before the 21st of December 16:46 UTC. The same user credentials are valid to access this site.
