grid_global: Generate a global hexagon grid

In hexify: Equal-Area Hex Grids on the 'Snyder' 'ISEA' 'Icosahedron'

Generate a global hexagon grid

Description

Creates hexagon polygons covering the entire Earth.

Usage

grid_global(grid, wrap_dateline = TRUE)

Arguments

grid	A HexGridInfo object specifying the grid parameters
wrap_dateline	Logical. If TRUE (default), antimeridian-crossing polygons are split at +/-180 degrees. Set to FALSE for orthographic/globe projections where wrapping creates gaps.

Details

This function generates a complete global grid by sampling points densely across the globe. For large grids (many small cells), consider using grid_rect() to generate regional subsets.

Value

sf object with hexagon polygons

Examples

# Coarse global grid
grid <- hex_grid(area_km2 = 100000)
global <- grid_global(grid)
plot(global)
