<p>
Imagery data is treated as raster maps in GRASS, but there are a number of
special modules specifically designed to help with image processing.
<P>
For details, see the
<a href="../grass64/manuals/html64_user/imageryintro.html">imagery</a> and
<a href="../grass64/manuals/html64_user/rasterintro.html">raster map</a>
processing guides.
<P>
* Orthophoto processing: orthorectification of aerial photographs with
 new GUI tools, i.ortho.photo, i.points, i.vpoints, ...
<P>
* Cluster analysis: i.class, i.cluster
