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
r.stream.snap_simple matches stream related spatial objects like
species occurrences or migration barriers to stream pixels.
