The attached pdf shows the basin map output by r.watershed based on a 10m<br>
DEM and a threshold of 150000. The NHD level 6 subbasins are outlined in<br>
black and the 1:24K NHD streams are in blue.<br>
<br>
The small white areas at the bottom left and center right appear to be<br>
external to defined sub-basins. But I don't know how to interpret the larger<br>
white areas with streams in them (center and top). The top margin is an<br>
international boundary so I can understand not being able to completely<br>
define sub-basins across that boundary since the DEM doesn't reach that far<br>
north, but it's not consistently white.<br>
<br>
Please help me interpret the white areas with vector streams.<br></blockquote><div><br></div><div>Please post information about the region, <a href="http://r.info">r.info</a> of the map and the command line of r.watershed that you use. Also, do you use a mask? </div>
