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=False, verbose=False, quiet=False, superquiet=False)

Example:

gs.run_command("r.soils.texture", sand="name", clay="name", scheme="name", output="name")

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
