Use case

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.

About the data

This sample uses a U.S. National Weather Service radar map. Because WMS services generate map images on-the-fly, this layer is always up-to-date with the latest NOAA NEXRAD radar observations.
