WMS stands for Web Map Service. WMS produces maps of spatially referenced data dynamically from geographic information. These maps are rendered in a pictorial format for example PNG, GIF or JPEG. The operations can be done using a standard web browser which submitt requests in form of a URL. In most cases WMS acts as a client like Quantum GIS. The OGC WMS specification standardizes the way in which maps are requested by clients and the way that servers describe their data holdings.
