Water bodies detection based on NDWI and the otsu threshold v1.0.0
NDVI mean from Landsat-8/9 acquisitions
- one input, no output
The CWL includes:
- one input parameter of type Directory
- there are no output parameters of type Directory
This corner-case 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-9 acquisition
