Create a Base Sampling Grid for Use in Multiple Projects

Description

Create a Base Sampling Grid for Use in Multiple Projects

Usage

make_base_grid(
  dir.out = NULL,
  overwrite = FALSE,
  countries = c("US", "CA"),
  states = NULL,
  crs.target = 4326,
  hexagonal = TRUE,
  grid.size = 0.5,
  conterminousUSA = TRUE,
  ...
)

Arguments

dir.out	Where to save the resulting grid (as .RDS).
overwrite	TRUE will overwrite existing grid.rds in dir.out
countries	Vector of countries. Defaults to a base map of USA and CAN, unless arg states is provided. If arg states is provided, this argument will be ignored. Must be specified using ISO-A2
states	Vector of states to which the spatial grid will be clipped. Must be specified using ISO 3166-2 (see https://en.wikipedia.org/wiki/ISO_3166-2)
crs.target	Target CRS number for spatial grid.
hexagonal	logical if TRUE will produce a spatial grid with hexagonal, as opposed to rectangular, cells
grid.size	numeric size (relative to units defining crs.target) of resulting cell. E.g., if crs.target==4326 a value of gridsize=1.0 equals ~111.11km
conterminousUSA	logical if TRUE will remove Hawaii and Alaska. Default TRUE to reduce computation times and extent of sptaial grid.
...	Additional arguments
