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:

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

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.


Install GDAL on the command line first, e.g., using homebrew

brew install gdal

Then install rgeos

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


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
