It would be great if it could handle also integer maps as input. Maybe a quantization option, like in i.atcor would be a possibility to scale input from 1 - 10000 to 0.0 - 1.0 by applying the quantization factor (default to 1)? I am thinking of e.g. linked (r.external) Sentinel-2 data here, which comes with integer values... Ideally, also output should be saved as integer if input is integer, reapplying the quantization. That could save a processing step and would possibly allow to save some storage space.",enhancement,new,normal,7.8.3,Imagery,svn-trunk,,i.topo.corr,,All,All
