%description
Spatial analyses involving binning require that every bin have the same
area, but this is impossible using a rectangular grid laid over the Earth
or over any projection of the Earth. Discrete global grids use hexagons,
triangles, and diamonds to overcome this issue, overlaying the Earth with
equally-sized bins. This package provides utilities for working with
discrete global grids, along with utilities to aid in plotting such data.
