<div class="moz-cite-prefix">I would try to do a VRT file that
describes both raster files and work with that.<br>

I don't have an good example but maybe this could get You started
together with the GDAL docs.<br>

<div>Hi</div>
<div><br>
</div>
<div>I have two raster files one for vegetation and one for
population density.</div>
<div>The two rasters (tif's) are at different scales</div>
<div><br>
</div>
<div>I am using value based classification to paint the map
green where vegetation values are high.</div>
<div>Is there a way I can classify based on values from the two
separate files in the same layer</div>
<div>I can't see how this will work as you can only have one
data item per layer?? (but worth asking)</div>
<div><br>
</div>
<div>I am wanting to be able to do something like</div>
<div>
<pre style="overflow:auto;padding:10px;line-height:1.2em;border:1px solid rgb(198,201,203);font-size:1.2em;margin-top:1.5em;margin-bottom:1.5em">EXPRESSION ([veg] <= 50 and [population] > 500)</pre>
</div>
<div><br>
</div>
<div>The only option I can think of is to make the two files
into a single multiband tiff? This seems wasteful as one is
much lower resolution then the other. </div>
<div><br>
</div>
<div>thoughts??</div>
<div><br>
</div>
<div>thanks</div>
