<p><font size="4">Hi Sibylle:</font></p>
<p><font size="4"><br>
</font></p>
<p><font size="4">So the problem is getting all the vector quadrats
as a single value into the "zones" raster? Then I would use the
parameters:</font></p>
<p><font size="4" face="monospace">'attr=val value=1' </font><font
size="4">in the v.to.rast step.</font><font size="4"
face="monospace"><br>
</font></p>
<p><font size="4" face="monospace"><br>
</font></p>
<p><font size="4">Here, below, are the steps I tried. At the start I
would point out that the raster
"al_pres_apple_spring_merged.tif" has very low variance, with
almost all cells at value 0. When you make of boxplot of these
values, you get a very narrow band near to the median value,
very near to zero. Maybe that's what is causing the confusion.<br>
