How are WMS service layers transmitted to ArcMap?
With WMS services, the legends for layers are transmitted over the Internet as one image containing all the symbols. Although ArcMap supports legend entries with multiple symbols in its table of contents, ArcMap expects these entries to contain multiple images, one image per symbol.
How to view a WMS in a web browser?
The GetMap request can be used to view a WMS in a web browser. Just cut and paste this URL into your browser to view the WMS image; changing the BBOX values alters the geographic extent of the area viewed. The GetCapabilities request provides information about the image layers contained in the WMS.
How do I add layers to my WMS file?
Click the layer or layers that you want to list in the table of contents. You can hold down CTRL or SHIFT to choose multiple WMS sublayers. Click the Right Arrow to add selected layers or the Double Right Arrow to add all WMS sublayers.

How are web mapping services used in ArcMap?
Web Mapping Service (WMS) services can be used in ArcMap (as well as in ArcScene and ArcGlobe) as map layers. Following are some common tasks for working with WMS service layers.
Where to find the legend of a WMS layer?
When a WMS service includes legend information, you can view the WMS sublayer’s symbology in the table of contents by clicking the expansion control next to a sublayer. The legends for the layers in WMS services are all hidden by default, since accessing a legend for each layer in a WMS service requires sending a separate request to the server.
Can a WMS layer contain any number of styles?
The WMS specification allows a WMS layer to contain any number of styles. You can choose from the available styles using the Styles tab of the WMS service sublayer’s Layer Properties dialog box. If the WMS service does not support styles, you will see Legend not available in the preview window.
What happens when an image exceeds a limit in ArcMap?
ArcMap also places a limit on the size, height, and width (in pixels) of an image it will display in the table of contents. When the image received for a layer in a WMS service exceeds this limit, no legend is displayed for the layer.
