WMS is an OGC standard for displaying maps from images that are dynamically-generated on a web server. WMS is particularly useful for data that changes frequently, contains cartographically complex detail, or requires an open source data standard.
How to use the sample
The map will load automatically when the sample starts.
How it works
Create a WmsLayer specifying the URL of the service and the names of layers you want to display.
Note: The name comes from the 'Name' property, not the 'Title' property. On many services, the title is human-readable while the name is a numeric identifier.
Add the layer to the map as an operational layer with map.getOperationalLayers().add(wmsLayer).
