v0.9.0 - 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:

• first beta release, the code is in excellent shape with respect to features, stability and performance
• breaking change: naming is now always modelled from SAFE XML tags ported to snake_case #101
• add the option to select a burst by its burst_id in crop_burst_dataset #100
• add a make_stac_item(ds.attrs) helper function
• add group metadata attributes to data arrays #101
• added a CF compliance checker to the test suite and fixed several CF issues #98

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
• reads uncompressed and compressed SAFE data products on the local computer or on a network via fsspec - depends on rasterio>=1.3a3
• supports larger-than-memory and distributed data access via Dask and rioxarray / rasterio / GDAL
• provides a few helpers for simple operations involving metadata like croppping 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.
