classifications and legends it is confused with land use. It is defined
as:</p>
<p><i>Land cover is the observed (bio)physical cover on the earth's surface.</i></p>
<p>When considering land cover in a very pure and strict sense it should
be confined to describe vegetation and man-made features. Consequently,
areas where the surface consists of bare rock or bare soil are
describing <i>land</i> itself rather than land <i>cover</i>. Also, it is
disputable whether water surfaces are real land cover. However, in
practise, the scientific community usually describes those aspects under
the term land cover.</p></div></blockquote><div><br></div><div>Cheers</div><div>Martin<br></div></div>
