Display a layer from a Web Map Tile Service.
Use case
WMTS services can have several layers. You can use Runtime to explore the layers available from a service. This would commonly be used to enable a browsing experience where users can choose which layers they want to display at run time.
How to use the sample
Pan and zoom to explore the WMTS layer, which is displayed automatically.
How it works
- Create a
WmtsService
using the URL of the WMTS Service. - After loading the WMTS service, get the list of
WmtsLayerInfos
from the service info:service.getServiceInfo().getLayerInfos()
- Use one of the layer infos to create a new
WmtsLayer(layerInfos.get(0))
- Set it as the maps' basemap with
map.setBasemap(new Basemap(wmtsLayer))
.
Relevant API
- WmtsLayer
- WmtsLayerInfo
- WmtsService
- WmtsServiceInfo
About the data
The map visualizes world time zones.
