Short for Web Map Service, WMS is the production of spatially referenced data dynamically from geographic information. The map itself is an actual portrayal of geographic information presented as a digital image file for display on a computer. WMS maps are in picture formats such as PNG, GIF or JPEG, or as Scalable Vector Graphics (SVG) or Web Computer Graphics Metafile (WebCGM) formats. WMS is commonly used in the Geographic Information Systems industry.
