r.mcda.topsis

Generates a MCDA map based on TOPSIS algorthm.

r.mcda.topsis criteria=name [,name,...] preferences=character weights=float [,float,...] topsismap=string [--verbose] [--quiet] [--qq] [--ui]

Example:

r.mcda.topsis criteria=name preferences=character weights=0.0 topsismap=string

grass.script.run_command("r.mcda.topsis", criteria, preferences, weights, topsismap, verbose=None, quiet=None, superquiet=None)

Example:

gs.run_command("r.mcda.topsis", criteria="name", preferences="character", weights=0.0, topsismap="string")

grass.tools.Tools.r_mcda_topsis(criteria, preferences, weights, topsismap, verbose=None, quiet=None, superquiet=None)

Example:

tools = Tools()
tools.r_mcda_topsis(criteria="name", preferences="character", weights=0.0, topsismap="string")

This grass.tools API is experimental in version 8.5 and expected to be stable in version 8.6.

Parameters

criteria=name [,name,...] [required]
    Name of criteria raster maps
preferences=character [required]
    preference (gain,cost)
weights=float [,float,...] [required]
    weights (w1,w2,...,wn)
topsismap=string [required]
    Ranked raster map
--help
    Print usage summary
--verbose
    Verbose module output
--quiet
    Quiet module output
--qq
    Very quiet module output
--ui
    Force launching GUI dialog

criteria : str | list[str], required
    Name of criteria raster maps
    Used as: input, raster, name
preferences : str, required
    preference (gain,cost)
    Used as: character
weights : float | list[float] | str, required
    weights (w1,w2,...,wn)
topsismap : str, required
    Ranked raster map
    Used as: output
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

criteria : str | list[str], required
    Name of criteria raster maps
    Used as: input, raster, name
preferences : str, required
    preference (gain,cost)
    Used as: character
weights : float | list[float] | str, required
    weights (w1,w2,...,wn)
topsismap : str | type(np.ndarray) | type(np.array) | type(gs.array.array), required
    Ranked raster map
    Used as: output
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.mcda.topsis implements the ideal point algorithms based on TOPSIS model and returns a raster map shown the ranking geospatial alternatives. The user has to provide the weight values and preference (gain or cost) directly
