NAME
r.stream.variables - Calculation of contiguous stream-specific variables that account for the upstream environment (based on r.stream.watersheds).KEYWORDS
raster, stream, drainage, hydrologySYNOPSIS
r.stream.variables
r.stream.variables --helpr.stream.variables variable=name area=string [folder=name] [out_folder=name] output=method[,method,...] [scale=value] [cpu=float] [--help] [--verbose] [--quiet] [--ui]
Flags:
- --help
- Print usage summary
- --verbose
- Verbose module output
- --quiet
- Quiet module output
- --ui
- Force launching GUI dialog
Parameters:
- variable=name [required]
- Name of raster to be converted into a stream-specific variable
- area=string [required]
- Area of aggregation: across the sub-watersheds or only across sub-streams
- Options: watershed, stream
- folder=name
- Provide the full folder path (same as for r.stream.watersheds)
- Default: GISDBASE/folder_structure
- out_folder=name
- Provide the full folder path for the output stream-specific variable
- Default: GISDBASE/stream-specific_variables
- output=method[,method,...] [required]
- Provide the output aggregation method for the stream-specific variable
- upstream cells numbers, minimum, maximum, range, mean, standard deviation, coefficient of variation, sum. Output datatype is Int32
- Options: cells, min, max, range, mean, stddev, coeff_var, sum
- scale=value
- Provide a scale factor to multiply or divide the final stream-specific variable
- Provide it e.g. if input raster values are between -1 and 1, use scale=1000 to inicrease the number of decimals - all outputs will be rounded to integers
- Default: 1
- cpu=float
- Number of CPUs used for the parallel computation
- Default: 1
