I would like to identify the raster, in a r.series

Is there a way to do so ?<br>

<p>Hello Frank:</p>
<p><br>
</p>
<p>I used Vero's suggestion in a script I was working on some months
ago: I had a list of rasters, each represented a "station_id". I
used g.list to create the list of raster names, and fed that into
r.series input=<list> method=max_raster.</p>
<p>Then I used r.reclass to get back the station_id from the list
index. I had a text file with matches between the index of the
raster in the list, and it's actual "station_id". So r.reclass
returned a raster with each pixel value being the station_id of
the maximum raster in the list.</p>
<p>HTH</p>
