[GRASS-user] stream network

[Will Fields]

Hi Janet,

Can you give some more information about what you mean by larger watershed
basins?  Did you do any preprocessing of the elevation raster before you
tried to extract the stream networks?  Were you using an elevation raster
that had been merged from different rasters?  I've ran into issues in the
past where "seams" along the original edges of a raster resulted in odd
stream networks.
