sld:RasterSymbol

        A "RasterSymbol" is used to specify the rendering of
        raster/matrix-coverage data (e.g., satellite images, DEMs).
      

Element information

Content

• Sequence [1..1]
  from type sld:SymbolType
  sld:Name [0..1]    
  sld:Description [0..1]     A "Description" gives human-readable descriptive information for the object it is included within.
  sld:BaseSymbol [0..1]     A "BaseSymbol" defines the default properties of a symbol to be those of an external symbol, which will frequently be inside of an OGC symbol(izer) repository. The symbol properties given in-line override the base-symbol properties.
  1. sld:Geometry [0..1]     A Geometry gives reference to a (the) geometry property of a feature to be used for rendering.
  2. sld:Opacity [0..1]    
  3. sld:ChannelSelection [0..1]     "ChannelSelection" specifies the false-color channel selection for a multi-spectral raster source.
  4. sld:OverlapBehavior [0..1]     "OverlapBehavior" tells a system how to behave when multiple raster images in a layer overlap each other, for example with satellite-image scenes.
  5. sld:ColorMap [0..1]     A "ColorMap" defines either the colors of a pallet-type raster source or the mapping of numeric pixel values to colors.
  6. sld:ContrastEnhancement [0..1]     "ContrastEnhancement" defines the 'stretching' of contrast for a channel of a false-color image or for a whole grey/color image. Contrast enhancement is used to make ground features in images more visible.
  7. sld:ShadedRelief [0..1]     "ShadedRelief" specifies the application of relief shading (or "hill shading") to a DEM raster to give it somewhat of a three-dimensional effect and to make elevation changes more visible.
  8. sld:ImageOutline [0..1]     "ImageOutline" specifies how individual source rasters in a multi-raster set (such as a set of satellite-image scenes) should be outlined to make the individual-image locations visible.
