Leaflet.Basemaps

A tile driven basemaps control for Leaflet.

It allows you to create a user interface control for choosing the basemap used on the map, based on a tile from a the underlying tile service.

See the example.

Tested with Leaflet 1.0.0-rc3

Install

From Bower:

bower install Leaflet.Basemaps

From NPM:

npm install leaflet-basemaps

Usage

Include the CSS:

<link rel="stylesheet" href="L.Control.Basemaps.css" />

Include the JavaScript:

<script src="L.Control.Basemaps-min.js"></script>

The control expects a list of TileLayer instances, constructed in the normal way.

An optional layer property can be added in the options for each basemap, and this will be used to populate the tooltip (HTML title attribute) for that basemap.

Each basemap is represented using a tile from the underlying tile service. Choose the tile x, y, z that provides the best looking representative basemap image for your application.

Note: this automatically adds the first basemap in your list to the map during initialization, so you don't need to add that TileLayer to your map.

Example usage:

var basemaps = [
