v0.4 - Alpha
What's new:
- Fixed chunking of measurement data
- Added a helper functions for simple operations involving metadata
- Start adding metadata to variables
Overview:
Overall the software is in the alpha phase and the usual caveats apply.
- 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
- Sentinel-1 Ground Range Detected (GRD):
- creates ready-to-use Xarray
Dataset
s 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
