A Leaflet plugin, adding support for defining a TileLayer in terms of several TileServer urls.

[Leaflet.MultiTileLayer][3]

Disclaimer

This was an evening hack trying to package a solution for something that we did at [Kartena][4]. A few days after I finished it I found another, much simpler, solution that can be seen in [this jsfiddle][5]. You should probably use that approach instead. However if you find any usages for this, please let me know.

Description

A [Leaflet][1] plugin, adding support for defining a [TileLayer][2] in terms of several TileServer urls.

Usage

var map = L.map('map').setView(L.latLng(57.7, 11.9), 12);

L.TileLayer.multi({
	14: { // this layer is shown at zoomlevels between minZoom and 14 (ie 0,1,..,13,14)
		url: 'http://otile{s}.mqcdn.com/tiles/1.0.0/osm/{z}/{x}/{y}.png',
		subdomains:'1234'
	},
	17: { // this layer is shown at zoomlevels between maxZoom of 
          // previous layer and 17 (ie 15, 16 and 17)
		url: 'http://server.arcgisonline.com/ArcGIS/' 
           + 'rest/services/World_Imagery/MapServer/tile/{z}/{y}/{x}'
	}
}, {
	minZoom: 0,
	maxZoom: 17,
