Application Package Pattern 8¶

The CWL includes:

one input parameter of type Directory
one output parameter of type Directory?

This scenario takes as input an acquisition, applies an algorithm and may or may not generate and output

Implementation: detects water bodies using the Normalized Difference Water Index (NDWI) and Otsu thresholding.
