Sentinel-2 Data Download Tutorial#

This tutorial demonstrates how to download Sentinel-2 data from the Sentinel official website.

1. Select data#

Go to the Sentinel official website: <https://scihub.copernicus.eu/dhus/#/home>, log in to your account (if you don’t have one, register), and select the desired data to add to your cart.

2. Download data#

2.2 Create .netrc file#

Tip

Creating .netrc file allows you to save the account and password information for websites. When the program downloads, it will automatically read the corresponding account and password from this file, eliminating the need for repeated user input.

To download Sentinel data, you need an account and password. If you don’t have one, please register on the official website.

Replace your_username and your_password in the code below with your own username and password registered on the Sentinel official website, and execute it in a Python editor.

from data_downloader import downloader

netrc = downloader.Netrc()
netrc.add('scihub.copernicus.eu','your_username','your_password')

After execution, a .netrc file will be created in the user’s directory.

Note

If the account or password is entered incorrectly, set overwrite=True in the code above to overwrite the account and password in the .netrc file.

netrc.add('scihub.copernicus.eu', 'your_username','your_password', overwrite=True)

2.3 Bulk Download#

Create a Python file, copy the code below, and modify the folder_out and url_file paths according to your situation. Then execute it to download files in bulk.

Tip

DataDownloader can automatically skip downloaded files and support resumable downloads. If the download is interrupted and some files are incomplete, simply re-execute this script.

from data_downloader import downloader, parse_urls

# File output directory, make sure this folder exists
folder_out = r'D:\Sentinel-2 Data'
# The products.meta4 file containing URLs downloaded in the first step
url_file = r'C:\Users\Your Username\Desktop\products.meta4'

# Parse the URL file
urls = parse_urls.from_sentinel_meta4(url_file)

# Download data
downloader.download_datas(urls, folder_out)
