Custom Tile URLs

There are many tileservers available that allow you to use specialist maps. Some are commercial and require payment but many are free although some require you to get a private key to ensure you don't abuse the usage limits. For example, you can use the following URL for Open Street Maps:

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

The Tile URL should be in z, x, y format. For example http://tile.openstreetmap.org/{z}/{x}/{y}.png. Tile URLs that include quadtree should use {q} or {quadtree} format in order for these to be loaded correctly.

TMS/Flipped Geometry option is also available for tile servers that require this option.
