make_2d_grid: Make a raster, point, or polygon grid from an sf polygon

In afsc-gap-products/akgfmaps: Alaska Groundfish and Ecosystem Survey Area Mapping

Make a raster, point, or polygon grid from an sf polygon

Description

Creates a raster (terra 'SpatRaster'), point grid (sf 'POINT'), or polygon mesh/'fishnet' (sf 'POLYGON') from an sf polygon.

Usage

make_2d_grid(
  obj,
  resolution = c(3704, 3704),
  output_type = "point",
  bbox = NULL,
  model = "semi-open",
  include_tile_center = FALSE
)

Arguments

obj	An sf polygon.
resolution	Resolution for grid cells. Default = c(3704, 3704), equivalent of 2x2 nautical miles.
output_type	Type of output as a 1L character vector ("point", "raster", "polygon).
bbox	Optional. A 4L numeric vector to define the edges of the interpolation grid c(xmin, ymin, xmax, ymax).
model	Character vector indicating the geometry model to use for st_intersection boundaries. Default = "semi-open"; for details see ?s2::s2_options
include_tile_center	Should the center point of each tile be included in the output? This helps with plotting data because the center point for grid locations after interecting with the stratum shapefile is not always the center of a grid cell since intersected cells are not always squares.
