In skgrange/gissr: Tools To Make Working With R and Spatial Data Easier

Functions to write GeoJSON files with usage analogous to write.table.

Description

write_geojson_js is a simple extension which adds a var to the GeoJSON string so leaflet and other JavaScript libraries can assign the objects easily.

Usage

write_geojson(sp, file, pretty = TRUE, round = NA)

write_geojson_js(sp, file, name = NA, pretty = TRUE, round = NA)

Arguments

sp	Spatial object to be written as GeoJSON file.
file	File name of GeoJSON file.
pretty	Format the JSON for readability.
round	How many decimal points should the coordinate pairs be exported with? Default is maximum but 6 is common for spatial data.
name	Name of JavaScript object (only used in write_geojson_js).
