sentinel1-reader 0.1.5

s1-reader

A package to read Sentinel-1 data into the ISCE3-compatible burst class.

Features

• Create ISCE3-compatible Sentinel1 burst class given:

  • S1 SAFE
  • subswath index
  • polarization
  • path to orbit directory

• Monotonically increasing bursts IDs.

🚨 This toolbox is still in pre-alpha stage and undergoing rapid development. 🚨

Install

1. Download source code:

git clone https://github.com/opera-adt/s1-reader.git

2. Install dependencies:

conda install -c conda-forge --file s1-reader/requirements.txt

3. Install s1-reader via pip:

# run "pip install -e" to install in development mode
python -m pip install ./s1-reader

Usage

The following sample code demonstrates how to process a single burst from a S1 SAFE zip:

import s1reader

zip_path = "S1A_IW_SLC__1SDV_20190909T134419_20190909T134446_028945_03483B_B9E1.zip"
swath_num = 2
pol = "VV"

# read orbits
orbit_dir = '/home/user/data/sentinel1_orbits'
orbit_path = s1reader.get_orbit_file_from_dir(zip_path, orbit_dir, auto_download=True)

# returns the list of the bursts
bursts = s1reader.load_bursts(zip_path, orbit_path, swath_num, pol)
burst_ids = [x.burst_id for x in bursts]
