Convert various data formats to/from GeoJSON or TopoJSON. This package focuses mostly on converting lists, data.frame's, numeric, SpatialPolygons, SpatialPolygonsDataFrame, and more to GeoJSON with the help of sf. You can currently read TopoJSON - writing TopoJSON will come in a future version of this package.
The core 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:
topojson_list() - convert
to GeoJSON or TopoJSON as R list format
topojson_json() - convert
to GeoJSON or TopoJSON as JSON
geojson_sp() - convert to a spatial object from
geojson_sf() - convert to an sf object from
topojson_read() - read a
GeoJSON/TopoJSON file from file path or URL
topojson_write() - write
a GeoJSON file locally (TopoJSON coming later)
Other interesting functions:
map_gist() - Create a GitHub gist (renders as an
map_leaf() - Create a local interactive map using the
geo2topo() - Convert GeoJSON to TopoJSON
topo2geo() - Convert TopoJSON to GeoJSON
All of the above functions have methods for various classes, including
SpatialPoints, and many more - which will try to do the right thing
based on the data you give as input.
