<DL>
<DD>The ChannelSelection element specifies the false-color channel selection
 for a multi-spectral raster source (such as a multi-band
 satellite-imagery source). Either a channel may be selected to display
 in each of red, green, and blue, or a single channel may be selected to
 display in grayscale.  (The spelling ?gray? is used since it seems to
 be more common on the Web than ?grey? by a ratio of about 3:1.)
 Contrast enhancement may be applied to each channel in isolation.
 Channels are identified by a system and data-dependent character
 identifier.  Commonly, channels will be labelled as ?1?, ?2?, etc.

<DD>The ColorMap element defines either the colors of a palette-type raster
 source or the mapping of fixed-numeric pixel values to colors. For
 example, a DEM raster giving elevations in meters above sea level can
 be translated to a colored image with a ColorMap.  The quantity
 attributes of a color-map are used for translating between numeric
 matrixes and color rasters and the ColorMap entries should be in order
 of increasing numeric quantity so that intermediate numeric values can
 be matched to a color (or be interpolated between two colors). Labels
 may be used for legends or may be used in the future to match character
 values. Not all systems can support opacity in colormaps.  The default
 opacity is 1.0 (fully opaque). Defaults for quantity and label are
