Styled Layer Descriptor

Styled Layer Descriptor (SLD ) is an XML schema that has been defined by the Open Geospatial Consortium ( OGC) to define the appearance of map layers. With the SLD presentation description language the appearance of vector and raster data can be described. Typical use an SLD definition is notify a Web Map Service (WMS ) as a specific map layer to be displayed. The representation can thus be independent of the geometry, but not on the geometry type (point, line, polygon, etc. ) store.

In August 2007, the SLD specification was divided into two new specifications: Symbology Encoding (abbreviated SE) and Styled Layer Descriptor (short: SLD).

The Styled Layer Descriptor specification now describes only the protocol to let a WMS which style rules to be applied for a map layer. The actual description rules are now defined in a separate Symbology Encoding Specification.
