Convert various data formats to GeoJSON or TopoJSON

This package is a utility to convert geographic data to GeoJSON and TopoJSON formats. Nothing else. We hope to do this one job very well, and handle all reasonable use cases.

Functions in this package are organized first around what you're working with or want to get, GeoJSON or TopoJSON, then convert to or read from various formats:

  • geojson_list()
    /
    topojson_list()
    - convert to GeoJSON/TopoJSON as R list format
  • geojson_json()
    /
    topojson_json()
    - convert to GeoJSON/TopoJSON as JSON
  • geojson_sp()
    - convert output of
    geojson_list()
    or
    geojson_json()
    to
    sp
    spatial objects
  • geojson_sf()
    - convert output of
    geojson_list()
    or
    geojson_json()
    to
    sf
    objects
  • geojson_read()
    /
    topojson_read()
    - read a GeoJSON/TopoJSON file from file path or URL
  • geojson_write()
    /
    topojson_write()
    - write a GeoJSON/TopoJSON file locally

Each of the above functions have methods for various objects/classes, including

numeric
,
data.frame
,
list
,
SpatialPolygons
,
SpatialLines
,
SpatialPoints
, etc.

Additional functions:

  • map_gist()
    - push up a GeoJSON or topojson file as a GitHub gist (renders as an interactive map)
  • map_leaf()
    - create a local interactive map using the
    leaflet
    package

Install

A note about installing

rgeos
- built on top of C libraries, and installation often causes trouble for Linux users because no binaries are provided on CRAN for those platforms. Other dependencies in
geojsonio
should install easily automatically when you install
geojsonio
.

Mac

Install

GDAL
on the command line first, e.g., using
homebrew
brew install gdal

Then install

rgeos
install.packages("rgeos", type = "source")

Linux

Get deps first

sudo apt-get install libgdal1-dev libgdal-dev libgeos-c1 libproj-dev

Note: if you have trouble installing rgeos, try installing

libgeos++-dev

Then install

rgeos
install.packages("rgeos", type = "source")

Install geojsonio

Stable version from CRAN
