DESCRIPTION

44       d.shade will drape a color raster map over a  shaded  relief  map.   In
45       place  of shaded relief, any raster map can be used including aspect or
46       slope.  The color raster map is usually an elevation  raster  map  with
47       colorful  color  table (as opposed to gray scale color table). However,
48       any raster map can be used including categorical raster maps.
49
50       The advantage of this module is that it allows visualizing  the  shaded
51       map  without  a  need  to create a new raster which would combine both.
52       Comparing to creating shaded relief as semi-transparent overlay on  the
53       color raster map, this module gives result with more saturated colors.
54
55       The   input   for   this  module  can  be  created  for  example  using
56       r.slope.aspect or r.relief
57       .

NOTES

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

EXAMPLES

64       In  this  example,  the aspect map in the North Carolina sample dataset
65       location is used to hillshade the elevation map:
66       g.region raster=aspect -p
67       d.mon wx0
68       d.shade shade=aspect color=elevation
69
70       Figure: A detail of raster created by applying shading effect of aspect
71       to  elevation  raster  map from North Carolina dataset elevation map In
72       this next example, a shaded relief raster map is created  and  used  to
73       create a colorized hillshade:
74       g.region raster=elevation
75       r.relief input=elevation output=elevation_shaded_relief
76       d.mon wx1
77       d.shade shade=elevation_shaded_relief color=elevation
78       Interesting  visualizations can be created using different color tables
79       for elevation raster map, for example using haxby color table.
