NAME

r.stream.snap_simple - Match stream related spatial objects to stream pixels

KEYWORDS

raster, snap, stream, points

SYNOPSIS

r.stream.snap_simple
r.stream.snap_simple --help
r.stream.snap_simple [-a] [objects_vector=name] [type=string[,string,...]] [layer=string] [where=sql_query] [objects_raster=name] direction=name [distance=integer] [pixel_type=string] output=name [--overwrite] [--help] [--verbose] [--quiet] [--ui]

Flags:

-a
Treat input slope as absolute values
--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:

objects_vector=name
Vector map with objects locations
Input vector map with locations of stream related spatial objects (e.g. species occurrences, dams, wires...)
type=string[,string,...]
Input feature type
Options: point, line, boundary, centroid, area
Default: point,line,boundary,centroid,area
layer=string
Layer number or name
Vector features can have category values in different layers. This number determines which layer to use. When used with direct OGR access this is the layer name.
Default: 1
where=sql_query
WHERE conditions of SQL statement without 'where' keyword
Example: income < 1000 and population >= 10000
objects_raster=name
Raster map with objects locations
Input raster map with locations of stream related spatial objects (e.g. species occurrences, dams, wires...)
direction=name [required]
Raster map with flow direction
Input raster map with flow direction (e.g. from r.stream.extract)
distance=integer
Snapping distance (in map units) (default=0)
Snapping distance (in map units) for snapping occurrences and barriers to closest stream pixel
Default: 0
pixel_type=string
Method for representing (default=both)
Snapping distance (in map units) for snapping occurrences and barriers to closest stream pixel
Options: inlet, outlet, both, all
Default: both
output=name [required]
Vector points map with isolated clusters of the network
Snapping distance (in map units) for snapping occurrences and barriers to closest stream pixel
