weighted_band_sum
Calculate a weighted sum of raster bands using specified weights to generate a single-band output, enabling precise geospatial data analysis. Input multi-band raster, define weights, and save the result to a destination file.
Instructions
Compute a weighted sum of all bands in a raster using specified weights.
Parameters:
- source: Path to the input multi-band raster file.
- weights: List of weights (must match number of bands and sum to 1).
- destination: Path to save the output single-band raster.
