I/O for GeoJSON
Description
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.
Package organization
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:
-
geojson_list()
/topojson_list()
- convert to GeoJSON or TopoJSON as R list format -
geojson_json()
/topojson_json()
- convert to GeoJSON or TopoJSON as JSON -
geojson_sp()
- convert to a spatial object fromgeojson_list
orgeojson_json
-
geojson_sf()
- convert to an sf object fromgeojson_list
orgeojson_json
-
geojson_read()
/topojson_read()
- read a GeoJSON/TopoJSON file from file path or URL -
geojson_write()
/topojson_write()
- write a GeoJSON file locally (TopoJSON coming later)
Other interesting functions:
-
map_gist()
- Create a GitHub gist (renders as an interactive map) -
map_leaf()
- Create a local interactive map using theleaflet
package -
geo2topo()
- Convert GeoJSON to TopoJSON -
topo2geo()
- Convert TopoJSON to GeoJSON
All of the above functions have methods for various classes, including
numeric
vectors, data.frame
, list
, SpatialPolygons
, SpatialLines
,
SpatialPoints
, and many more - which will try to do the right thing
based on the data you give as input.
