Using the Open Street Map OSM Mapnik tile server with leafet.js

The following post is a portion of the Leaflet Tips and Tricks book which is free to download. To use this post in context, consider it with the others in this blog or just download the the book as a pdf / epub or mobi .

Open Street Map OSM Mapnik

This is the standard tile server in use for Open Street Map.

URL Template

http://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png

Usage policy

The best place to view the detail on the usage policy for Open Street Maps tiles is from their tile usage policy wiki page. The main concern with usage is the load placed on their resources which are finite considering their position as a volunteer run service. So be gentle and when in doubt, check out the wiki.

        L.tileLayer(
            'http://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png', {
            attribution: '&copy; ' + mapLink + ' Contributors',
            maxZoom: 18,
            }).addTo(map);

I will post separate examples of the usage of different tile servers as separate posts. Or you can find them all in Leaflet Tips and Tricks.
