**Important Note**

The javascript library is opensource and distributed under BSD 2 Licence.

However, display maps requires to display layers provided by tiles servers, that
requires ressources.

**For testing purpose**

You can use the openStreetMap url ``https://tile.openstreetmap.org/{z}/{x}/{y}.png`` or other, listed in that page : https://wiki.openstreetmap.org/wiki/Tile_servers

Apart from very limited testing purposes, you should not use the tiles supplied by OpenStreetMap.org itself. OpenStreetMap is a volunteer-run non-profit body and cannot supply tiles for large-scale commercial use.

**Regular / High Usage**
