 Hi, in my case null values are scattered all over the map, see attached
 screenshot (the large spots however are water). I realised that the
 command line i actually gave is slightly different from the one i posted
 earlier (if matters) and is:

 r.stream.distance --verbose stream_rast=stream1500 direction=drainage
 elevation=dem method=downstream distance=dist2stream_2
 difference=elev2stream_2 memory=2000

 Thanks
