 A web-mapping service (WMTS) is an Open Geospatial Consortium (OGC) standard for serving images of map data. There are many open data sets available in this format that you can use with Azure Maps. This type of service can be used with a tile layer if the service supports the `EPSG:3857` coordinate reference system (CRS). When using a WMS service, set the width and height parameters to the value supported by the service, be sure to set this value in the `tileSize` option. In the formatted URL, set the `BBOX` parameter of the service with the `{bbox-epsg-3857}` placeholder.
