This sample shows how to create a tile layer which points to a Web Mapping Tile Service (WMTS).
In this case aerial imagery from the US Geological Survey.
To add a WMTS to Azure Maps as a Tile Layer, the follow URL parameters would typically be set to the following;
<ul>
<li>TileMatrixSet: EPSG:3857 or GoogleMapsCompatible</li>
<li>TileMatrix: {z}</li>
<li>TileRow: {y}</li>
<li>TileCol: {x}</li>
</ul>
The data in this sample comes from the <a href="https://viewer.nationalmap.gov/services/" target="_blank">U.S. Geological Survey (USGS) National Map</a>.
