r.soils.texture
Define soil texture from sand and clay grid.
r.soils.texture sand=name clay=name scheme=name output=name [--overwrite] [--verbose] [--quiet] [--qq] [--ui]
Example:
r.soils.texture sand=name clay=name scheme=name output=name
grass.script.run_command("r.soils.texture", sand, clay, scheme, output, overwrite=None, verbose=None, quiet=None, superquiet=None)
Example:
gs.run_command("r.soils.texture", sand="name", clay="name", scheme="name", output="name")
grass.tools.Tools.r_soils_texture(sand, clay, scheme, output, overwrite=None, verbose=None, quiet=None, superquiet=None)
Example:
tools = Tools()
tools.r_soils_texture(sand="name", clay="name", scheme="name", output="name")
This grass.tools API is experimental in version 8.5 and expected to be stable in version 8.6.
Parameters
sand=name [required]
Name of input sand map [0-100]
clay=name [required]
Name of input clay map [0-100]
scheme=name [required]
Text file with texture scheme
output=name [required]
Name for output raster map
--overwrite
Allow output files to overwrite existing files
--help
Print usage summary
--verbose
Verbose module output
--quiet
Quiet module output
--qq
Very quiet module output
--ui

sand : str, required
Name of input sand map [0-100]
Used as: input, raster, name
clay : str, required
Name of input clay map [0-100]
Used as: input, raster, name
scheme : str, required
Text file with texture scheme
Used as: input, file, name
output : str, required
Name for output raster map
Used as: output, raster, name
overwrite : bool, optional
Allow output files to overwrite existing files
Default: None
verbose : bool, optional
Verbose module output
Default: None
quiet : bool, optional
Quiet module output
Default: None
superquiet : bool, optional
Very quiet module output
Default: None
sand : str | np.ndarray, required
Name of input sand map [0-100]
Used as: input, raster, name
clay : str | np.ndarray, required
Name of input clay map [0-100]
Used as: input, raster, name
scheme : str | io.StringIO, required
Text file with texture scheme
Used as: input, file, name
output : str | type(np.ndarray) | type(np.array) | type(gs.array.array), required
Name for output raster map
Used as: output, raster, name
overwrite : bool, optional
Allow output files to overwrite existing files
Default: None
verbose : bool, optional
Verbose module output
Default: None
quiet : bool, optional
Quiet module output
Default: None
superquiet : bool, optional
Very quiet module output
Default: None
Returns:
result : grass.tools.support.ToolResult | np.ndarray | tuple[np.ndarray] | None
If the tool produces text as standard output, a ToolResult object will be returned. Otherwise, None
will be returned. If an array type (e.g., np.ndarray) is used for one of the raster outputs, the result will be an array and will have the shape corresponding to the computational region. If an array type is used for more than one raster output, the result will be a tuple of arrays.
DESCRIPTION
r.soils.texture define soils texture from sand and clay distribution
grid and a texture scheme definition.
Sand and clay grid are simple grid theme; scheme file is text ASCII file
with *.dat extention like USDA.dat, FAO.dat and nternational.dat
supplied with source code module in scheme directory. You can download
*.dat files from the GRASS GIS addons
repository
