How to add a WMS service to ArcGIS Pro using the SDK

BerendVeldkamp

Adding a WMS service to ArcGIS Pro is very simple and straightforward, but you must know which classes to use. Since the documentation is severely lacking in examples, I thought I'd add it here.

Adding a WMTS or a WCS works exactly the same way, just alter the type of the connection variable.

Oh, and before anyone asks, Identify on a WMS only works if a geographical coordinate system is used. Projected does not work at this moment (BUG-000099054).

Greetings Berend,

Thank you for the example, that is very useful. However, if you were to adjust the code for WMS services that are secure with a username and password, how would you do this?

Also, is it possible to embed the credentials in the code so that when a user accesses the service they are NOT presented with an authentication window asking for credentials?

Thank you in advance.

Hello!

The ProSnippets:Map Authoring wiki page is where you can find snippets for creating various layers using the Pro API.

Here is a snippet that illustrates how to add a WMS service:

@MiguelEduardoParedes The following snippet below should work for you. I was not able to test this snippet because I couldn't configure a WMS service that requires user/password credentials, probably because I am using an older version of ArcGIS server. Upgrading my ArcGIS Server will take a while....

try
{
	// Create a connection to the WMS server
	var serverConnection = new CIMInternetServerConnection 
	{ 
		URL = @"https://sdk5.esri.com/arcgis/services/TestCreditsMap/MapServer/WMSServer",
		User="test",
		Password="test" 
	};
	var connection = new CIMWMSServiceConnection { ServerConnection = serverConnection };

	// Add a new layer to the map
	await QueuedTask.Run(() =>
	{
		var layer = LayerFactory.Instance.CreateLayer(connection, MapView.Active.Map);
	});
}
catch (Exception ex)
{
	MessageBox.Show($@"Error: {ex}");
}
