leafpm
is a plugin for leaflet
to provide map editing and drawing in R with
Leaflet.pm
. It is based
closely off of
leaflet.extras
addDrawToolbar()
. leafpm
is intended to supplement leaflet.extras
with better support for snapping and holes.
You can install the released version of leafpm from CRAN with:
install.packages("leafpm")
library(mapview)
library(leafpm)
library(sf)
outer1 = matrix(c(0,0,10,0,10,10,0,10,0,0),ncol=2, byrow=TRUE)
hole1 = matrix(c(1,1,1,2,2,2,2,1,1,1),ncol=2, byrow=TRUE)
hole2 = matrix(c(5,5,5,6,6,6,6,5,5,5),ncol=2, byrow=TRUE)
outer2 = matrix(c(11,0,11,1,12,1,12,0,11,0),ncol=2, byrow=TRUE)
pts1 = list(outer1, hole1, hole2)
pts2 = list(outer2)
pl1 = st_sf(geom = st_sfc(st_polygon(pts1)))
pl2 = st_sf(geom = st_sfc(st_polygon(pts2)))
mpl = st_sf(geom = st_combine(rbind(pl1, pl2)))
addPmToolbar(
mapview(mpl)@map,
targetGroup = "mpl"
)
leafpm
was designed to work as an editor in
mapedit
, so you can get your
edits back into the R
session. For instance,
#install.packages("mapedit")
library(mapedit)
drawFeatures(editor = "leafpm")
