A collection of tools for interactive manipulation of (spatial) data layers on leaflet web maps. Tools include editing of existing layers, creation of new layers through drawing of shapes (points, lines, polygons), deletion of shapes as well as cutting holes into existing shapes. Provides control over options to e.g. prevent self-intersection of polygons and lines or to enable/disable snapping to align shapes.
leafpm is a plugin for
to provide map editing and drawing in R with
Leaflet.pm. It is based
closely off of
leafpm is intended to supplement
with better support for snapping and holes.
You can install the released version of leafpm from CRAN with:
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")
