5.7.13 Web Map Server(WMS)/Background Image Control
Overview
The WMS Control displays imagery from WMS servers. A set of predefined links to WMS servers for topographic, shaded relief and aerial imagery is also provided with the Background Image control.

To use the pre-defined Background images simply select the Display->Special->Background Image menu item. To choose imagery from other web map servers bring up the Data Source Chooser, go to the Catalogs tab and enter the url that points to the Capabilities document of the desired WMS. We also provide links to a set of useful WMSs from the idvcatalog. If it is not in the Catalog pull down menu simply enter the url:

https://resources.unidata.ucar.edu/georesources/idvcatalog.xml
From this catalog open the Web Map Servers tab and select the WMS you would like to access.

The WMS Control makes request to the Web Map Server for an image that covers the area currently being displayed in the main display. Due to the time it takes to access remote servers the WMS Control does not request new images when the user pans and zooms.
