Extracts unique integer class values and computes summary statistics (pixel count, approximate area) for each class.
Usage
wapor_extract_crop_classes(
crop_mask,
exclude_nodata = TRUE,
min_pixels = 10,
nodata_values = c(0, 255, -9999, -32768, 65535, -3.4e+38)
)Arguments
- crop_mask
SpatRaster. A harmonized crop mask raster.
- exclude_nodata
Logical. If TRUE (default), filters out common nodata values (0, 255, -9999, -32768) from the class list.
- min_pixels
Integer. Minimum pixel count for a class to be included. Default is 10. This helps filter out very small spurious classes.
- nodata_values
Numeric vector. Values to treat as NoData.
