Discrete Global Grids

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.

README

This directory contains the 0-level adminstrative border of South Africa as a
shapefile.

The file is used by dggridR for demonstrating how a shapefile can be used to
produce a grid which overlays, for example, a country, or any other geolocated
polygon.

The file was drawn from freely available data at:

    http://www.diva-gis.org/gdata

I have used "http://www.mapshaper.org/" to simplify the shapefile in order to
reduce the file size.
