Create a bounding box — create

This function creates a bounding box from either cardinal coordinates (north, south, east and west) or center coordinates and dimensions (center longitude and latitude, and size of width and height).

Usage

create_bbox(
  north = NULL,
  south = NULL,
  east = NULL,
  west = NULL,
  center_lon = NULL,
  center_lat = NULL,
  width = NULL,
  height = NULL
)

Arguments

north: The northernmost latitude.
south: The southernmost latitude.
east: The easternmost longitude.
west: The westernmost longitude.
center_lon: The center longitude.
center_lat: The center latitude.
width: The width of the bounding box.
height: The height of the bounding box.

Value

A 2x2 matrix representing the bounding box.

Examples

# Create a bounding box from cardinal coordinates
create_bbox(
  north =  35.1899,
  south =  35.1399,
  east  = 136.9524,
  west  = 136.8524
)
#>        min      max
#> x 136.8524 136.9524
#> y  35.1399  35.1899

# Create a bounding box from center coordinates and dimensions
create_bbox(
  center_lon = 136.9024,
  center_lat =  35.1649,
  width      = 0.10,
  height     = 0.05
)
#>        min      max
