<br>
I think you should do<br>
<br>
raster2=if(isnull(raster1),0,raster1)<br>

I am trying to do something really simple but not finding the
right way to do it.
<div>
<div>I need to convert nulls into zeros. I have done this:<br>
<i>r.mapcalc "raster2 = if(raster1 = null(), 0, raster1)" </i></div>
<div><i>r.mapcalc "raster2 = if(raster1 == null(), 0, raster1)"
</i><i><br>
</i>
<div>But this convert all cells into nulls.
<div><br>
</div>
<div>I have tried another approach with r.reclass, rules:</div>
<div>
<div>
null/null()/no data/nodata...=0</div>
<div>1=1</div>
<div>2=2</div>
<div>3=2</div>
<div>4=2</div>
<div>5=2</div>
</div>
<div><br>
</div>
<div>No fun, all I get is an ERROR: null/null()/no
data/nodata...=0 </div>
<div><br>
</div>
<div>
What I'm doing wrong?<br>
