sarsen

Algorithms and utilities for Synthetic Aperture Radar (SAR) sensors -- scripts

Description

Enables cloud-native SAR processing via Xarray and Dask.

Sarsen is a Python library and command line tool with the following functionalities:

* provides algorithms to terrain-correct satellite SAR data

- geometric terrain correction (geocoding)

* fast mode: to terrain-correct images

* accurate mode: for interferometric processing

- radiometric terrain correction (gamma flattening)

* accesses SAR data via xarray-sentinel:

- supports most Sentinel-1 data products as distributed by ESA:

* Sentinel-1 Single Look Complex (SLC) SM/IW/EW

* Sentinel-1 Ground Range Detected (GRD) SM/IW/EW

- reads uncompressed and compressed SAFE data products on the local

computer or on a network via fsspec

* accesses DEM data via rioxarray:

- reads local and remote data in virtually any raster format via

rasterio / GDAL

* supports larger-than-memory and distributed data access and processing

via Dask

- efficient geometric terrain-correction for a full GRD

- efficient radiometric terrain-correction for a full GRD.

This package contain executable programs provided by the sarsen Python package.
