Calculate shade map at the ground level

Calculate shade map at the ground level

Usage

make_shademap_ground(shademap.canopy = NULL, cover.ras = NULL, filename = NULL)

Arguments

shademap.canopy

A SpatRaster with the illumination at the canopy level, made with make_shademap().

cover.ras

A SpatRaster containing cover classes (ground, vegetation, buildings...). See rasterize_lidar_cover_class().

filename

Character. Output filename. Note that if a file already exists with that name, it will be overwritten.

Value

A (possibly multilayer) SpatRaster object with the intensity of illumination at the ground level

Examples

if (FALSE) {
lidar <- read_lidar(system.file("extdata", "PlazaNueva.laz", package = "CityShadeMapper"))
cover.ras <- rasterize_lidar_cover_class(lidar)
shaderas.canopy <- make_shademap(heights, date = "2022-10-15", hour = 13)
shaderas.ground <- make_shademap_ground(shaderas.canopy, cover.ras)

## Alternatively, call make_shademap directly:
heights <- calc_heights_from_lidar(lidar)
shaderas.ground <- make_shademap(heights, date = "2022-10-15", hour = 13,
  type = "ground", cover.ras = cover.ras)
}
