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.
Value
sf object with hexagon polygons
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.
Examples
# Coarse global grid
grid <- hex_grid(area_km2 = 100000)
global <- grid_global(grid)
plot(global)
