Limitations of WMS Servers
A WMS server typically renders a layer as an RGB image. In some rare cases, you can request the actual data, rather than a pictorial representation, from a WMS server. Most often, you need to create either a Web Coverage Service (WCS) request, for raster data, or a Web Feature Service (WFS) request, for vector data. The Mapping Toolbox does not support WCS and WFS requests.
