 <P>
 GRASS aspect maps are measured using Cartesian conventions, i.e. in degrees 
 counterclockwise from east. e.g.:
-<pre>

+<div class="code"><pre>
 90  North
 180 West
 270 South
-0,360 East</pre>
-<P>
+0,360 East
+</pre></div>

 They can be created from a raster elevation map with <em>r.slope.aspect</em>.
 <P>
 Compass type aspect maps are measured in degrees clockwise from north.
