Application Package Pattern 6¶

The CWL includes:

one input parameter of type Directory
there are no output parameters of type Directory

This scenario takes as input an acquisition, applies an algorithm and generates an output that is not a STAC Catalog

Implementation: derive the NDVI mean taking as input a Landsat-8/9 acquisition

`item`	`Directory`	Landsat-8/9 acquisition reference	Landsat-8/9 acquisition reference

Steps¶

Id	Runs	Label	Doc
