GEE Count Values in Single Band

This KNIME node processes a Google Earth Engine (GEE) image to count the number of pixels that match specified category codes within defined regions (Feature Collection). The results are returned as a Feature Collection with the counts of each category code per region.

Category Codes: Specify the category codes as a comma-separated string in the single band.

Scale: Set the image_scale to define the resolution at which the image reduction should be performed. This is crucial for accurate results.
