Sentinel-1 subpackage for stactools

This project contains multiple subpackages that work with different Sentinel 1 data products.

RTC

The stactools.sentinel1.rtc subpackage and stac sentinel1 rtc commands deal with the Sentinel 1 Radiometric Terrain Corrected (RTC) data hosted on AWS and produced by Indigo Ag. This data was processed from original Ground Range Detected (GRD) scenes into a Radiometrically Terrain Corrected, tiled product suitable for analysis.

See https://registry.opendata.aws/sentinel-1-rtc-indigo for more information about this dataset.

GRD

The stactools.sentinel1.grd subpackage and stac sentinel1 grd commands deal with Sentinel 1 Ground Range Detected (GRD) Level-1 product. It is used to create STAC Items from the SAFE manifest format of the data hosted on Microsoft Azure.
