Load example competition distribution raster data

Creates a raster layer from the example frgcompdata_example dataset included with the package. The raster is reconstructed from the stored metadata and populated with the associated competition distribution values.

Usage

get_example_frgcompdata(type = NULL)

Value

A RasterLayer containing example competition distribution data for the Forth Islands study area. The raster includes the correct extent, resolution, and coordinate reference system derived from the example metadata.

Details

This function provides a ready-to-use example raster for demonstrations, tutorials, and testing workflows.

The raster represents a competition distribution map, i.e. the distribution of conspecifics from surrounding colonies that may interact with the colony or SPA being simulated. This information is used throughout the seabORD model to estimate how competition from other colonies influences intake rate at different foraging locations.

The raster is reconstructed from the built-in frgcompdata_example dataset using raster_from_metadata() and populated with the associated competition distribution values.

The returned raster layer is named "Forth.Islands".
