The American Community Survey (ACS)
    <https://www.census.gov/programs-surveys/acs> offers geodatabases with
    geographic information and associated data of interest to researchers
    in the area. The goal of this package is to generate objects that
    allow us to access and consult the information available in various
    formats, such as in 'GeoPackage' format or in multidimensional 'ROLAP'
    (Relational On-Line Analytical Processing) star format.

Turn irregular polygons (such as geographical regions) into regular or hexagonal grids.
    This package enables the generation of regular (square) and hexagonal grids through the package 
    'sp' and then assigns the content of the existing polygons to the new grid using 
    the Hungarian algorithm, Kuhn (1955) (<doi:10.1007/978-3-540-68279-0_2>). 
    This prevents the need for manual generation of hexagonal grids or regular grids 
    that are supposed to reflect existing geography.

Tools for working with Gustavo Niemeyer's geohash coordinate system, including API for interacting with other common R GIS libraries.

Classes for 'GeoJSON' to make working with 'GeoJSON' easier.
    Includes S3 classes for 'GeoJSON' classes with brief summary output,
    and a few methods such as extracting and adding bounding boxes,
    properties, and coordinate reference systems; working with 
    newline delimited 'GeoJSON'; and serializing to/from 'Geobuf' binary 'GeoJSON' 
    format.

Convert data to 'GeoJSON' or 'TopoJSON' from various R
    classes, including vectors, lists, data frames, shape files, and
    spatial classes.  'geojsonio' does not aim to replace packages like
    'sp', 'rgdal', 'rgeos', but rather aims to be a high level client to
    simplify conversions of data from and to 'GeoJSON' and 'TopoJSON'.

Includes functions for processing GeoJson objects <https://en.wikipedia.org/wiki/GeoJSON> relying on 'RFC 7946' <https://datatracker.ietf.org/doc/pdf/rfc7946.pdf>. The geojson encoding is based on 'json11', a tiny JSON library for 'C++11' <https://github.com/dropbox/json11>. Furthermore, the source code is exported in R through the 'Rcpp' and 'RcppArmadillo' packages.
