coord_to_raster: Turn coordinates of outlets into rasters

Description

Given a set of coordinates in space (x, y), this function will return a rasterised version of that point in space.

Usage

coord_to_raster(outlet, out, overwrite = FALSE)

Value

Nothing.

Arguments

outlet

A single pair of Easting, Northing or long, lat coordinates as a numeric vector.

out

Whether the output files should be allowed to overwrite existing files. Defaults to FALSE.

Examples

# Will only run if GRASS is running
if(check_running()){
# Load data set
dem <- system.file("extdata", "dem.tif", package = "rdwplus")

# Set environment parameters
set_envir(dem)

# Read in data
raster_to_mapset(dem)

# Set coordinates to rasterise
coord_df <-  c(1098671, 6924794)

# Convert to raster
coord_to_raster(outlet = coord_df, out = "coords", overwrite = TRUE)

# Plot
plot_GRASS("dem.tif", col = topo.colors(15))
plot_GRASS("coords", col = "red", add = TRUE)
