 When working with floating point elevation models, no such aspect bias occurs.
 
 
-<h2>REFERENCE</h2>
+<h2>EXAMPLES</h2>
 
+In this example a slope, aspect, profile and tangential curvature map
+are computed from an elevation raster map (North Carolina sample
+dataset):
+
+<div class="code"><pre>
+g.region raster=elevation
+r.slope.aspect elevation=elevation slope=slope aspect=aspect pcurvature=pcurv tcurvature=tcurv
+
+# set nice color tables for output raster maps
+r.colors -n map=slope color=sepia
+r.colors map=aspect color=aspectcolr
+r.colors map=pcurv color=curvature
+r.colors map=tcurv color=curvature
+</pre></div>
