<P class=MsoNormal DEFANGED_STYLE="MARGIN: 0mm 0mm 0pt"><SPAN lang=EN-US><FONT size=2>But
the problem is the results were much smaller than the real

<P class=MsoNormal DEFANGED_STYLE="MARGIN: 0mm 0mm 0pt"><SPAN lang=EN-US><FONT size=2>The
real area of this lake was changed from 500km2 to 1200km2 in these 5

<P class=MsoNormal DEFANGED_STYLE="MARGIN: 0mm 0mm 0pt"><SPAN lang=EN-US><FONT size=2>So
my question is: why r.report gives me the wrong figured area
data?</FONT></SPAN></P>
