Get Game Pressure Raster for R4 Indicator

Creates a SpatRaster of game pressure index by department for use with the indicator_risk_browsing function.

Usage

get_game_pressure_raster(units, pressure_data = NULL, dept_boundaries = NULL)

Arguments

units

sf object. Forest parcels to determine spatial extent and CRS.

pressure_data

Data.frame from compute_game_pressure_index, or NULL to compute automatically.

dept_boundaries

sf object. Department boundaries with code_dept column, or NULL to download from IGN.

Value

A SpatRaster with game pressure index (0-100) per pixel, matching the extent and CRS of the input units.

Details

This function: 1. Downloads/computes game pressure index by department 2. Downloads department boundaries if not provided 3. Rasterizes the pressure values 4. Returns a raster for use with indicator_risk_browsing(game_density = ...)

Examples

if (FALSE) { # \dontrun{
library(nemeton)
library(sf)

# Load parcels
parcels <- st_read("parcels.gpkg")

# Get game pressure raster
game_raster <- get_game_pressure_raster(parcels)

# Use with R4 indicator
result <- indicator_risk_browsing(
  parcels,
  species_field = "essence",
  game_density = game_raster
)
} # }
