NAME

       d.shade  - Drapes a color raster over an shaded relief or aspect map.

KEYWORDS

       display, elevation, relief, hillshade, visualization

SYNOPSIS

       d.shade
       d.shade --help
       d.shade  shade=name  color=name   [brighten=integer]    [--help]   [--verbose]   [--quiet]
       [--ui]

   Flags:
       --help
           Print usage summary

       --verbose
           Verbose module output

       --quiet
           Quiet module output

       --ui
           Force launching GUI dialog

   Parameters:
       shade=name [required]
           Name of shaded relief or aspect raster map

       color=name [required]
           Name of raster to drape over relief raster map
           Typically, this raster is elevation or other colorful raster

       brighten=integer
           Percent to brighten
           Options: -99-99
           Default: 0

DESCRIPTION

       d.shade will drape a color raster map over a  shaded  relief  map.   In  place  of  shaded
       relief,  any  raster  map  can be used including aspect or slope.  The color raster map is
       usually an elevation raster map with colorful color table (as opposed to gray scale  color
       table). However, any raster map can be used including categorical raster maps.

       The  advantage  of this module is that it allows visualizing the shaded map without a need
       to create a new raster which would combine both.  Comparing to creating shaded  relief  as
       semi-transparent  overlay  on  the  color  raster  map, this module gives result with more
       saturated colors.

       The input for this module can be created for example using r.slope.aspect or r.relief
       .

NOTES

       Refer to the d.his help page for more details;  d.shade  is  simply  a  frontend  to  that
       module.

EXAMPLES

       In  this  example, the aspect map in the North Carolina sample dataset location is used to
       hillshade the elevation map:
       g.region raster=aspect -p
       d.mon wx0
       d.shade shade=aspect color=elevation

       Figure: A detail of raster created by applying  shading  effect  of  aspect  to  elevation
       raster map from North Carolina dataset elevation map In this next example, a shaded relief
       raster map is created and used to create a colorized hillshade:
       g.region raster=elevation
       r.relief input=elevation output=elevation_shaded_relief
       d.mon wx1
       d.shade shade=elevation_shaded_relief color=elevation
       Interesting visualizations can be created  using  different  color  tables  for  elevation
       raster map, for example using haxby color table.
