Application Package Pattern 2¶

The CWL includes:

two input parameters of type Directory
one output parameter of type Directory

This scenario typically takes as input one pre-event acquisition, one post-even acquisition, applies an algorithm and produces a result

Implementation: delineate water bodies using NDWI and Otsu automatic threshold taking as input two Landsat-8/9 acquisitions
