splnr_get_boundary() allows to create an sf object of your planning region either based on specific coordinate information, or rnaturalearth inputs such as ocean data. Creating a boundary is often the first step in conservation planning and a requirement for downstream function sin spatialplanr.
Arguments
- Limits
The limits of the boundary. This can either be a 4 element numeric named vector (c(xmin = 150, xmax = 160, ymin = -40, ymax = -30)), a vector of ocean/sea names, or a vector of EEZs.,
- Type
The type of Limits being provided. Options are "Ocean" or "EEZ". (not required if numeric or "Global" limits are provided)
- res
The resolution (in degrees) from which to create the boundary polygon if numeric limits are provided.
- cCRS
The CRS the boundary is to be returned in
Examples
Bndry <- splnr_get_boundary(Limits = "North Atlantic Ocean", Type = "Ocean")
