xarray-sentinel - v0.9.5 - Beta

Easily explore and access the SAR data products of the Copernicus Sentinel-1 satellite mission in Python.

This Open Source project is sponsored by B-Open - https://www.bopen.eu.

What's new:

• Acknowledge that full fsspec support is now broken, see #127, and implement a workaround that work in simple cases.

Overview:

xarray-sentinel is a Python library and Xarray backend with the following functionalities:

• supports the following data products as distributed by ESA:
  • Sentinel-1 Ground Range Detected (GRD):
    • Stripmap (SM)
    • Interferometric Wide Swath (IW)
    • Extra Wide Swath (EW)
  • Sentinel-1 Single Look Complex (SLC) SM/IW/EW
• creates ready-to-use Xarray Datasets that map the data lazily and efficiently in terms of both memory usage and disk / network access
• reads all SAR imagery data: GRD images, SLC swaths and SLC bursts
• reads several metadata elements: satellite orbit and attitude, ground control points, radiometric calibration look up tables, Doppler centroid estimation and more
• (partially broken, see #127) reads uncompressed and compressed SAFE data products on the local computer or on a network via fsspec - depends on rasterio >= 1.3.0
• supports larger-than-memory and distributed data access via Dask and rioxarray / rasterio / GDAL
• provides a few helpers for simple operations involving metadata like cropping individual bursts out of IW SLC swaths applying radiometric calibration polynomials and converting slant to ground range for GRD products

Overall, the software is in the beta phase and the usual caveats apply.
