Compute dispersal or spread map (Generic Engine) — compute

Low-level function to apply spatial processing (Convolution or External algorithms) to a raster. It handles NA masking and method dispatch to Julia if necessary.

Usage

compute_dispersal(x, method = "convolution", options = list(), mask = NULL)

Arguments

x: SpatRaster. Source layer to disperse.
method: Character. "convolution" or "omniscape" (placeholder).
options: List. Parameters (e.g., `kernel` for convolution).
mask: SpatRaster (optional). A mask to apply after dispersion (e.g., maintain original NA structure).

Value

A SpatRaster object containing the dispersed values.
