| This sample shows how to create a tile layer which points to a Web Mapping Tile Service (WMTS). | |
| This method is a simple way to add WMTS onto the map, for a more robust option, take a look at the <a href="/index.html?search=wmts">OGC Map Layer examples</a>. | |
| The data in this sample is 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>. | |
