R Documentation

Convert between GeoJSON and SHP

Description

Convert from SHP (shapefile) to GeoJSON, or from GeoJSON to SHP.

Usage

geojson_shp(
  geom.path = paste0(system.file(package = "eamenaR"), "/extdata/Waypoints.kmz"),
  geom.types = c("POINT", "LINE", "POLYGON"),
  export = TRUE,
  dirOut = paste0(system.file(package = "eamenaR"), "/results/"),
  geojson.name = "Waypoints",
  select.name = "EAMENA ID",
  select.fields = c("EAMENA ID", "Resource Name", "resourceid"),
  verbose = TRUE
)

Arguments

geom.path	path to the SHP/GeoJSONfile.
geom.types	types of geometries ("POINT", "LINE", "POLYGON") that will be selected. Default all: 'c("POINT", "LINE", "POLYGON")'.
export	if TRUE, will export SHP file in GeoJSON format, or GeoJSON file as SHP, if FALSE simple plot.
dirOut	path to folder where SHP/GeoJSON file will be created. Default, 'results/'.
geojson.name	name of SHP/GeoJSON that will be created without extension
select.name	for SHP export only. Field selected to be SHP name of the heritage place, default '"EAMENA ID"'.
select.fields	for SHP export only. SHP conversion remove large number of GeoJSON fields. This variable is used to select fields to preserve. Default: 'c("EAMENA ID","Resource Name", "resourceid")'.
verbose	if TRUE (default) then display different messages.

Value

GeoJSON file or SHP file, depending on input file.

Examples

library(dplyr)

# GeoJSON to SHP, only POINTS
geojson_shp(geom.path = "C:/Rprojects/eamenaR/inst/extdata/caravanserail.geojson",
            geom.types = "POINT",
            dirOut = "C:/Rprojects/eamenaR/results/",
            export = T,
            geojson.name = "caravanserailOUT")


# GeoJSON to SHP, only POLYGONS
library(dplyr)

geojson_shp(geom.types = "POLYGON",
           geojson.name = "cvns-polygons",
           geom.path = paste0(system.file(package = "eamenaR"),
                              "/extdata/caravanserail.geojson"),
           dirOut = "C:/Rprojects/eamena-gee/data/")
