Function hillshadeGrid

hillshadeGrid(
    grid: RasterGrid,
    opts?: {
        altitude?: number;
        azimuth?: number;
        cellsizeX?: number;
        cellsizeY?: number;
        zFactor?: number;
    },
): RasterGrid
Hillshade — a shaded-relief illumination raster via Horn's method (gdaldem's default hillshade algorithm): 0 (dark) – 255 (bright). altitude/azimuth are the light source's elevation/compass bearing in degrees (defaults: gdaldem's own — a 45°-high sun from the NW).
Parameters
- grid: RasterGrid
- Optionalopts: {
      altitude?: number;
      azimuth?: number;
      cellsizeX?: number;
      cellsizeY?: number;
      zFactor?: number;
  } = {}
Returns RasterGrid
