[GRASS-user] r.flow: units for flow accumulation

   The r.flow manual tells us that "Flowline density downhill or uphill
output is given in a raster map flowaccumulation. The value in each grid
cell is the number of flowlines which pass through that grid cell, that
means the number of flowlines from thec [sic] entire map which have segment
endpoints within that cell."

   Please suggest a legend title for this map that nontechnical audiences
will understand. Can I explain this map in the report text as "the upstream
areas draining to downstream points?" Or, is there a better, nontechnical,
way of interpreting this map?
