leaflet-rd

Leaflet.RD

Deze plugin voegt ondersteuning voor het Rijksdriehoeksstelsel toe aan Leaflet. Gebruik het meegelverde coördinatensysteem bij het aanmaken van een nieuwe kaart. Leaflet is dan meteen geschikt voor het tonen van bijvoorbeeld kaartlagen uit PDOK.

This plugin adds support for the Amersfoort / RD New coordinate system. Created for leaflet 1.0 and up.

Usage

Standalone

Include the javascript file on your page behind both Leaflet and Proj4js

Node

Require the 'leaflet-rd' package.

Setup Leaflet

Leaflet.RD adds a projection under L.projection.RD and a CRS under L.CRS.RD.

To immediately start using RD resources on your map set the CRS of your Leaflet map to L.CRS.RD:

var map = L.map("map", {
    crs: L.CRS.RD,
});

The plugin exports L.CRS.RD, in node the following is also possible:

var rd = require("leaflet-rd");

var map = L.map("map", {
    crs: rd,
});

Projecting Markers and Vector Layers

Markers and Vector Layers still expect latlng input. Project points using L.projection.RD.unproject(point) or map.options.crs.projection.unproject. You can convert GeoJson-data using reproject, as an added convenience an proj4 defenition string is located at L.projection.RD.pro4def.
