Easily access SAR data products of the Copernicus Sentinel-1 satellite mission


Easily access and explore the SAR data products of the Copernicus Sentinel-1 satellite mission in Python. 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 `Dataset`s that map the data
    lazily and efficiently in terms of both memory usage and disk/network
  * 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
  * 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, converting slant to ground range for GRD
    products and computing geospatial metadata.
