XSAR is a distributed Level 1 Synthetic Aperture Radar (SAR) file reader
designed to write efficient distributed processing algorithms with xarray
and dask.
.
It currently handles Level-1 Sentinel-1 and Radarsat-2 data in SAFE format,
as found on scihub or PEPS.
.
XSAR rely on `xarray.open_rasterio`, rasterio and GDAL to read digital_number
from SAFE product to return an `xarray.Dataset` object with dask chunks.
LUTs are decoded from XML files and applied to digital_number, following
official ESA thermal de-noising document and ESA Sentinel-1 Product
Specification.
.
End user can directly use for example sigma0 variable, or the de-noised
sigma0 computed from digital_number and by applying relevant LUTs.
.
Since XSAR rely on dask, it have a small memory footprint: variables are
read from file and computed only if needed.
