%description
Provides functions to build and use hexagonal discrete global grids using
the Icosahedral Snyder Equal Area ('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.
