Download precise orbit files for Sentinel 1 products

Project description

Build Status

Sentinel EOF

Tool to download Sentinel 1 precise/restituted orbit files (.EOF files) for processing SLCs

Setup and installation

pip install sentineleof

or through conda:

conda install -c conda-forge sentineleof

This will put the executable eof on your path

If you have a bunch of Sentinel 1 zip files (or unzipped SAFE folders), you can simply run


and download either the precise orbit files, or, if the POEORB files have not been released, the restituted RESORB files.


eof --search-path /path/to/safe_files/ --save-dir ./orbits/

will search /path/to/safe_files/ for Sentinel-1 scenes, and save the .EOF files to ./orbits/ (creating it if it does not exist)

Command Line Interface Reference

The command line tool in was made using the click library.

$ eof --help
Usage: eof [OPTIONS]

  Download Sentinel precise orbit files.

  Saves files to `save-dir` (default = current directory)

  Download EOFs for specific date, or searches for Sentinel files in --path.
  Will find both ".SAFE" and ".zip" files matching Sentinel-1 naming
  convention. With no arguments, searches current directory for Sentinel 1

  -p, --search-path DIRECTORY  Path of interest for finding Sentinel products.
                               [default: .]

  --save-dir DIRECTORY         Directory to save output .EOF files into
                               [default: .]

  --sentinel-file PATH         Specify path to download only 1 .EOF for a
                               Sentinel-1 file/folder

  -d, --date TEXT              Validity date for EOF to download
  -m, --mission [S1A|S1B]      Optionally specify Sentinel satellite to
                               download (default: gets both S1A and S1B)

  --help                       Show this message and exit.

To use the function from python, you can pass a list of dates:

from import download_eofs

download_eofs([datetime.datetime(2018, 5, 3, 0, 0, 0)])
download_eofs(['20180503', '20180507'], ['S1A', 'S1B'])
