4. Readers

Readers are the first component used in Geo2Grid processing. Their main responsibility is to extract input satellite imager data and the associated metadata from user provided input files. The data that readers distribute to other Geo2Grid components are called products (“datasets” in SatPy terminology).

The number and type of products that can be created is dependent upon the input datasets that are provided. Composites, such as RGBs, require a specific set of band combinations to be present. All products that can be created for a given input dataset can be determined by using the --list-products option.
