How are styles stored?
• Raster and vector files don’t contain styles. They are storedin separate files:
• ArcGIS Layer file (.lyr)
• QGIS Layer Style File (.qml)
• These formats are not standards and therefore notcompatible
• The OGC standard for styling of GIS data: Styled LayerDescriptor (SLD)

Styled Layer Descriptor (SLD)
• A Styled Layer Descriptor (SLD) is an XML schema specified by the Open Geospatial Consortium (OGC) for describing the appearance of map layers (both vector and raster)
• SLDs are used in GeoServer to style WMS/WFS/WCS layers

Create SLD files
1. Style layer in QGIS
• Vector:
−add style
−save style as .sld file
• Raster:
−add style
−use SLD4raster plugin to save style as .sld file or to directlyupload to GeoServer
