dem <- system.file("extdata", "dem.tif", package = "rdwplus")
sites <- system.file("extdata", "site.shp", package = "rdwplus")

# Set environment parameters and import data to GRASS
set_envir(dem)
vector_to_mapset(vectors = sites)

# Point to raster
point_to_raster(outlets = "site", out = "sites_rast.tif", overwrite = TRUE)
