Hi all,

I would like to identify the raster, in a r.series calculation for min
(or max), where the result is coming from.

Is there a way to do so ?

max_raster, min_raster in r.series will give you the index of the raster map in the series containing either max or min values

Is that what you need?

Hello Frank:


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.

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.

Thank you

Frank
