Pattern 8
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.
