<DD>The interpretation of Geometry is system-dependent, as raster data may
 be organized differently from feature data, though omitting this
 element selects the default raster-data source.  Geometry-type
 transformations are also system-dependent and it is assumed that this
 capability will be little used.

<DL>
<DD>The ImageOutline element specifies that individual source rasters in a
 multi-raster set (such as a set of satellite-image scenes) should be
 outlined with either a LineStringSymbol or PolygonSymbol. It is defined
 as:
 <pre>
 &lt;xs:element name="ImageOutline"&gt;
   &lt;xs:complexType&gt;
     &lt;xs:choice&gt;
       &lt;xs:element ref="sld:LineSymbolizer"/&gt;

     &lt;/xs:choice&gt;
   &lt;/xs:complexType&gt;
 &lt;/xs:element&gt;
 </pre>
 An Opacity of 0.0 can be selected for the main raster to avoid rendering
 the main-raster pixels, or an opacity can be used for a
 PolygonSymbolizer Fill to allow the main-raster data be visible through
 the fill.

<DL>
<DD>The OverlapBehavior element tells a system how to behave when multiple
 raster images in a layer overlap each other, for example with
 satellite-image scenes. LATEST_ON_TOP and EARLIEST_ON_TOP refer to the
 time the scene was captured. AVERAGE means to average multiple scenes
 together. This can produce blurry results if the source images are not
 perfectly aligned in their geo-referencing. RANDOM means to select an
 image (or piece thereof) randomly and place it on top.  This can
 produce crisper results than AVERAGE potentially more efficiently than
 LATEST_ON_TOP or EARLIEST_ON_TOP. The default behaviour is
 system-dependent.

<DL>
<DD>The ShadedRelief element selects the application of relief shading (or
 ?hill shading?) to an image for a three-dimensional visual effect.  It
 is defined as: Exact parameters of the shading are system-dependent
 (for now).  If the BrightnessOnly flag is ?0? (false, default), the
 shading is applied to the layer being rendered as the current
 RasterSymbol. If BrightnessOnly is ?1? (true), the shading is applied
 to the brightness of the colors in the rendering canvas generated so
 far by other layers, with the effect of relief-shading these other
 layers. The default for BrightnessOnly is ?0? (false).  The
 ReliefFactor gives the amount of exaggeration to use for the height of
 the ?hills.?  A value of around 55 (times) gives reasonable results for
 Earth-based DEMs. The default value is system-dependent.
