I would like to use the Montgomery method to extract streams (exp~2
from the paper). What should the threshold value be? And in general
what should the threshold value be? I am working in the southeastern
coastal plain (USA), which is characterized by low gradient (if this
helps).
for flat areas Montgomery's method is not a good option. Generally that
method was created and tested on areas with gradient > 5%.
I am using 1m resolution LIDAR data. I would like to extract
the most realistic map of streams that I can.
Chmmm... what you mean realistic? Maybe use existing stream network will
be the best solution?
For coastal plains where is no real vallyes the r.watershed's treeshold
with -b option seems to be best option
I am also trying to
track down the inttermitance perminance threshold. Any guidance would
be greatly appreciated.
kindest regards,
