Plot a baseline flight-distance raster

Creates a map of baseline flight distances from a breeding colony to accessible foraging locations and overlays coastlines for geographical context.

Usage

plot_fltdist_base(
  fltdist_base,
  title = "Coastline and baseline flight distance",
  zoom = FALSE
)

Arguments

fltdist_base

A raster::RasterLayer object containing baseline flight distances, such as the object returned by get_example_fltdist_base().

title

Character string giving the plot title. Defaults to "Coastline and baseline flight distance".

zoom

Logical. If TRUE, zooms the map to the extent of fltdist_base plus a 10 km buffer. Defaults to FALSE.

Value

A ggplot2::ggplot() object showing the baseline flight-distance raster and coastline.

Details

The input raster represents distance by sea from a breeding colony or SPA to each accessible raster cell. These distances are used by seabORD to calculate travel time and the energetic costs associated with foraging trips.

Raster cells with a value of zero are converted to missing values before plotting. Non-missing values are displayed using a continuous viridis colour scale.

The coastline data supplied with the package are transformed to the coordinate reference system of fltdist_base before plotting.
