+<h2>DESCRIPTION</h2>
-<EM>r3.stats</EM> calculates volume statistics for 3D raster maps.
+<em>r3.stats</em> calculates volume statistics for 3D raster maps.
Volumes are created on base of value subranges or groups of equal values.
The default number of subranges is 20 and can vary from 1 to infinite.
-Larger subranges will result in larger memory consumption.
+Larger number of subranges will result in larger memory consumption.
The volumes are calculated in qubic meters. Null values are marked with "*".
-If the flag <em>-e</em> is set, the number of subrange will be ignored.
+If the flag <em>-e</em> is set, the number of subranges will be ignored.

+As with most GRASS 3D raster map modules, <em>r3.stats</em> operates on the cell

+<p>
The region setting will not effect the memory consumption of this module.
The number of subranges in case of value range calculation or the number of
equal value groups effect the memory consumption and the calculation time.
-You can expect a huge time consumption to calculate the equal value groups (flag <em>-e</em>)
-if you use large region settings + maps which have many equal value groups (> 100000).
+The user can expect a huge time consumption to calculate the equal value groups (flag <em>-e</em>)

+<h2>EXAMPLES</h2>
+<h3>Lausanne FOSS4G 2006 3D demo dataset example</h3>
The 3D raster map <em>geology</em> has three values. Each value represents
a specific geological layer, clay = 1, sand = 2 and bedrock = 3. To calculate
the volume of each geological layer, we can use the flag <em>-e</em> to group
equal values into single volumes.
