Create hexagonal grid — iso

Create a hexagonal grid from an sf object.

Usage

iso_grid(x, resolution = 9)

Arguments

x: An sf object the convex hull of which will determine the hex grid
resolution: The resolution of the hex grid

Value

An sfc object

Details

See the documentation of the upstream h3 library for more information. Note: default value of 9 represents around 0.1 km^2, you may way to consider higher values (e.g. 10, which is around 0.015 km^2 or 15k m^2) for more detailed analysis or lower values for larger areas.

Note

This function is a wrapper for h3o::sfc_to_cells and h3o::flatten_h3. It assumes that the input object has a geographic (lon/lat) coordinate system, e.g. EPSG:4326.
