globe_centers

Named list of lon/lat coordinates for common globe views.
Used by <code>plot_globe</code> when center is specified as a string.

datasets

Provides functions to build and use hexagonal discrete global grids
using the 'Snyder' 'ISEA' projection ('Snyder' 1992
<doi:10.3138/27H7-8K88-4882-1752>) and the 'H3' hierarchical hexagonal system
('Uber' Technologies). Implements the 'ISEA' discrete global grid system
('Sahr', 'White' and 'Kimerling' 2003 <doi:10.1559/152304003100011090>).
Includes a fast 'C++' core for 'ISEA' projection and aperture quantization,
an included 'H3' v4.4.1 C library for native 'H3' grid operations, and
'sf'/'terra'-compatible R wrappers for grid generation and coordinate assignment.
Output is compatible with 'dggridR' for interoperability.
