raster_algebra
Perform addition or subtraction on raster band data, automatically aligning mismatched rasters, and save the output as a new geospatial file for efficient geospatial analysis.
Instructions
Perform algebraic operations (addition or subtraction) on two raster bands,
handling alignment issues automatically.
Parameters:
- raster1: Path to the first raster (.tif).
- raster2: Path to the second raster (.tif).
- band_index: Index of the band to process (1-based index).
- operation: Either "add" or "subtract" to specify the calculation.
- destination: Path to save the result as a new raster.
The function aligns rasters if needed, applies the selected operation, and saves the result.
