SYNOPSIS

v.stream.profiler

v.stream.profiler --help

v.stream.profiler cat=string streams=name [outstream=name] [direction=string] [elevation=name] [accumulation=name] [slope=name] [units=string] [accum_mult=float] [window=name] [plots=string[,string,...]] [outfile_original=string] [outfile_smoothed=string] [--overwrite] [--help] [--verbose] [--quiet] [--ui]

Flags:

--overwrite: Allow output files to overwrite existing files
--help: Print usage summary
--verbose: Verbose module output
--quiet: Quiet module output
--ui: Force launching GUI dialog

Parameters:

cat=string [required]: Starting line segment category
streams=name [required]: Vector input of stream network created by r.stream.extract; Or data source for direct OGR access
outstream=name: Vector output stream; Name for output vector map
direction=string: Which directon to march: up or down; Options: upstream, downstream; Default: downstream
elevation=name: Topography (DEM); Name of input raster map
accumulation=name: Flow accumulation raster; Name of input raster map
slope=name: Map of slope created by r.slope.area; Name of input raster map
units=string: Flow accumulation units; Options: m2, km2, cumecs, cfs
accum_mult=float: Multiplier to convert flow accumulation to your chosen unit; Default: 1
window=name: Averaging distance [map units]; Name of input raster map
plots=string[,string,...]: Plots to generate; Options: LongProfile, SlopeAccum, SlopeDistance, AccumDistance
outfile_original=string: output file for data on original grid
outfile_smoothed=string: output file for data on smoothed grid

DESCRIPTION

v.stream.profiler builds and exports plots and data sets of river long profiles, slope-accumulation (e.g., slope-area), and more for topographic analysis. It currently works only in a downstream-directed walk, for a single channel, from the chosen segment until the downstream-most point in the network. It takes in the adjacency structure supplied by v.stream.network.
