This example uses a SLD file to style the vector features. The style to be used is either determined by the NamedLayer and IsDefault properties in the sld file, or can directly be applied by addressing a style from the styles hash with the UserStyle name from the sld file as key. Select a new style for the WaterBodies layer below:
