Download precise orbit files for Sentinel 1 products

Project description

Sentinel EOF

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

Setup and installation

pip install sentineleof

This will put the executable eof on your path

virtualenv is optional but recommended.

Command Line Interface Reference

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

$ eof --help
Usage: eof [OPTIONS]

  Download Sentinel precise orbit files.

  Saves files to current directory, regardless of what --path is given to
  search.

  Download EOFs for specific date, or searches for Sentinel files in --path.
  With no arguments, searches current directory for Sentinel 1 products

Options:
  -r, --date TEXT          Validity date for EOF to download
  -m, --mission [S1A|S1B]  Sentinel satellite to download (None 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 eof.download import download_eofs

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

parsers.py

Class to deal with extracting relevant data from SAR filenames. Example:

from parsers import Sentinel

parser = Sentinel('S1A_IW_SLC__1SDV_20180408T043025_20180408T043053_021371_024C9B_1B70.zip')
parser.start_time
    datetime.datetime(2018, 4, 8, 4, 30, 25)
